Question 31
Which Fortinet SD-WAN feature allows administrators to define backup paths for critical applications in case the primary path fails?
A) Path Conditioning
B) SLA-Based Routing
C) Backup Path Configuration
D) Application Steering
Answer: C) Backup Path Configuration
Explanation:
Backup Path Configuration in Fortinet SD-WAN allows administrators to predefine alternative paths for critical applications, ensuring continuity of service in case the primary WAN link fails or becomes unavailable. This feature works alongside SLA monitoring and performance metrics to automatically redirect traffic to a backup path that meets the required performance standards. By creating predefined backup routes, administrators can maintain application availability and reduce downtime, especially for real-time or mission-critical applications such as VoIP, video conferencing, ERP, and cloud-hosted services. Backup Path Configuration provides organizations with greater resilience by planning for link failures rather than relying solely on reactive mechanisms. It ensures that application traffic continues to flow over alternative paths without manual intervention, supporting high availability and uninterrupted business operations.
Path Conditioning enhances the reliability of individual WAN links by mitigating packet loss, jitter, and latency. While it helps maintain consistent performance over degraded links, it does not define or enforce alternative routes for traffic in case of complete link failure. Path Conditioning ensures stability within a link but does not provide a mechanism for preplanned rerouting, making it insufficient for creating backup paths.
SLA-Based Routing monitors WAN links against predefined performance thresholds, such as latency, jitter, and packet loss. It dynamically reroutes traffic when a link fails to meet these criteria. However, SLA-Based Routing does not allow administrators to explicitly define backup paths; it relies on real-time link monitoring to make routing decisions. While it ensures performance compliance and rerouting based on SLA violations, Backup Path Configuration provides more predictable and controlled routing alternatives, particularly for applications that require guaranteed failover paths.
Application Steering directs traffic based on the application type, business priority, and link performance. It ensures that high-priority applications follow the optimal path under normal conditions but does not inherently provide a predefined backup path. Steering relies on performance monitoring and dynamic decision-making to select the best available link rather than executing a preplanned backup path strategy. It optimizes routing but is reactive rather than preconfigured.
Backup Path Configuration is the correct answer because it specifically enables administrators to define alternative routes for critical applications in advance. Unlike Path Conditioning, which stabilizes individual links, SLA-Based Routing, which dynamically reroutes based on performance, or Application Steering, which optimizes routing for high-priority traffic, Backup Path Configuration ensures a controlled, predictable, and resilient network design. It allows organizations to maintain business continuity, reduce downtime, and ensure that essential applications remain operational even in the event of primary link failure. By predefining alternative routes, enterprises can guarantee high availability, streamline disaster recovery planning, and maintain consistent performance across multiple WAN connections.
Question 32
Which Fortinet SD-WAN component analyzes WAN link performance to support routing and prioritization decisions?
A) WAN Path Monitor
B) Application Steering Engine
C) Path Conditioning
D) Link Load Balancer
Answer: A) WAN Path Monitor
Explanation:
WAN Path Monitor is a Fortinet SD-WAN component that continuously measures the performance of WAN links, providing critical data for routing and traffic prioritization decisions. It collects metrics such as latency, jitter, packet loss, and throughput for each WAN connection. This real-time performance analysis enables SD-WAN mechanisms to make informed decisions about which links are suitable for specific applications or flows, ensuring that latency-sensitive or high-priority traffic is directed over optimal paths. By monitoring WAN link performance, administrators gain visibility into network conditions and can enforce service level agreements, implement dynamic rerouting, and maintain predictable application performance. WAN Path Monitor is foundational for intelligent SD-WAN operations because it provides the quantitative data needed to balance performance, reliability, and application requirements across multiple WAN connections.
Application Steering Engine uses data about link quality, application type, and business priorities to dynamically route traffic over the best-performing WAN path. While it makes routing decisions based on performance metrics, it relies on input from the WAN Path Monitor to understand the current conditions of each link. Without WAN Path Monitor, the steering engine would lack the necessary real-time performance insights and could not accurately direct traffic. The steering engine executes decisions rather than providing the underlying analysis of WAN performance.
Path Conditioning improves link reliability by mitigating packet loss, jitter, and latency. It works on individual links to stabilize traffic and maintain quality, particularly for real-time applications. While Path Conditioning enhances WAN performance and supports routing decisions indirectly, it does not provide comprehensive measurement or continuous analysis of WAN links. Its primary purpose is link stabilization rather than performance monitoring or data collection for informed routing.
Link Load Balancer distributes traffic across multiple WAN links to optimize bandwidth utilization. Although it helps prevent congestion and improves throughput, it does not analyze link performance metrics in real-time. Load balancing decisions are typically based on static weights, session counts, or round-robin algorithms rather than on dynamic performance measurement. Without WAN Path Monitor, load balancing could inadvertently send traffic over suboptimal or degraded links.
WAN Path Monitor is the correct answer because it provides continuous, real-time analysis of WAN link performance, enabling SD-WAN components to make informed decisions about routing, prioritization, and SLA compliance. Unlike Application Steering Engine, which executes routing decisions, Path Conditioning, which stabilizes links, or Link Load Balancer, which distributes traffic, WAN Path Monitor delivers the foundational performance data that supports all intelligent SD-WAN operations. Its monitoring capabilities allow administrators to identify underperforming links, ensure predictable application performance, and maintain high-quality service levels for critical applications across multiple branch locations or cloud connections. By supplying precise link metrics, WAN Path Monitor ensures that traffic is directed optimally, improving user experience, maintaining business continuity, and enabling proactive network management.
Question 33
Which Fortinet SD-WAN feature ensures that high-priority applications receive bandwidth before lower-priority applications during congestion?
A) Application Control
B) SLA-Based Routing
C) Path Conditioning
D) WAN Aggregation
Answer: A) Application Control
Explanation:
Application Control in Fortinet SD-WAN enables administrators to prioritize traffic by identifying and classifying applications and allocating bandwidth according to business priorities. During periods of congestion, high-priority applications such as VoIP, video conferencing, or ERP systems are given preferential treatment, ensuring that critical services maintain performance. Lower-priority traffic, such as bulk file downloads, social media, or non-critical updates, can be throttled or queued, preventing them from impacting essential operations. By applying policies that differentiate traffic based on application type, criticality, or user-defined rules, Application Control provides a mechanism to enforce Quality of Service (QoS) and maintain predictable network performance across multiple WAN links.
SLA-Based Routing monitors WAN links against latency, jitter, and packet loss thresholds and dynamically reroutes traffic if a link does not meet the defined service levels. While SLA-Based Routing ensures traffic flows over links that meet performance criteria, it does not inherently allocate bandwidth between high-priority and low-priority applications. SLA-Based Routing is focused on meeting link-level performance requirements rather than controlling traffic prioritization during congestion.
Path Conditioning mitigates packet loss, jitter, and latency on individual WAN links to improve the quality of real-time traffic. It stabilizes traffic on degraded links but does not allocate bandwidth or prioritize applications during periods of congestion. Its primary function is maintaining link quality rather than enforcing prioritization policies.
WAN Aggregation combines multiple WAN links to create a single logical path, improving total available bandwidth and providing redundancy. While aggregation increases capacity, it does not differentiate traffic or prioritize high-priority applications during congestion. Aggregation optimizes throughput but does not manage QoS or ensure that critical applications receive preferential treatment.
Application Control is the correct answer because it provides traffic identification and policy enforcement to prioritize high-priority applications and allocate bandwidth accordingly. Unlike SLA-Based Routing, which focuses on link-level performance, Path Conditioning, which stabilizes links, or WAN Aggregation, which increases capacity, Application Control ensures that essential applications maintain performance during network congestion. By enforcing prioritization policies, administrators can maintain user experience, prevent service degradation for critical applications, and optimize WAN utilization across multiple branches and cloud connections. It allows enterprises to balance network efficiency with business requirements, ensuring that mission-critical applications always have the resources they need while lower-priority traffic is managed appropriately.
Question 34
Which Fortinet SD-WAN feature allows administrators to define performance thresholds such as latency, jitter, and packet loss for specific applications?
A) SLA-Based Routing
B) Application Steering
C) WAN Aggregation
D) Path Conditioning
Answer: A) SLA-Based Routing
Explanation:
SLA-Based Routing in Fortinet SD-WAN allows administrators to define performance thresholds for latency, jitter, and packet loss for specific applications. By setting these thresholds, administrators ensure that each application uses only WAN links that meet the required service levels, maintaining consistent performance for mission-critical applications. SLA-Based Routing continuously monitors WAN link metrics against these thresholds and dynamically reroutes traffic if a link fails to meet the defined criteria. This proactive approach ensures that latency-sensitive applications like VoIP, video conferencing, ERP systems, or cloud-hosted services maintain high performance even under fluctuating network conditions. SLA-Based Routing provides a mechanism to enforce service levels, reduce the impact of underperforming links, and maintain predictable application behavior across multiple branches or WAN connections.
Application Steering dynamically selects the optimal path for traffic based on application type, business priority, and real-time link performance. While it ensures critical applications follow the best-performing paths, it does not inherently define specific performance thresholds for latency, jitter, or packet loss. Application Steering relies on monitoring data and policy rules to make path selection decisions, but lacks the granularity of threshold-based enforcement offered by SLA-Based Routing. Steering focuses on real-time optimization rather than strict performance compliance.
WAN Aggregation combines multiple WAN links into a single logical path to increase bandwidth and provide redundancy. While it improves overall throughput and can support high-bandwidth applications, it does not define or enforce performance thresholds for individual applications. Aggregation is focused on capacity enhancement rather than monitoring or controlling performance metrics, so it cannot ensure that latency-sensitive or jitter-sensitive applications meet predefined service levels.
Path Conditioning stabilizes individual WAN links by mitigating packet loss, jitter, and latency. While it enhances the quality of traffic over a degraded link, it does not allow administrators to define thresholds or enforce service level compliance for specific applications. Path Conditioning acts reactively to maintain traffic stability rather than proactively ensuring that links meet specific performance requirements.
SLA-Based Routing is the correct answer because it provides the capability to define explicit performance thresholds for latency, jitter, and packet loss for each application. Unlike Application Steering, which optimizes routing without fixed thresholds, WAN Aggregation, which increases bandwidth, or Path Conditioning, which stabilizes links, SLA-Based Routing actively monitors link metrics against preconfigured criteria and reroutes traffic as needed. This feature ensures consistent application performance, reduces the risk of service degradation, and enables enterprises to enforce service levels for critical business applications. By establishing performance thresholds, SLA-Based Routing allows proactive management of WAN links, supporting high availability, predictable user experience, and reliable delivery of mission-critical services across multiple branch offices and cloud environments.
Question 35
Which Fortinet SD-WAN component provides end-to-end visibility into application usage, bandwidth consumption, and WAN link performance across multiple sites?
A) SD-WAN Controller
B) WAN Path Monitor
C) Application Control
D) Path Conditioning
Answer: A) SD-WAN Controller
Explanation:
The SD-WAN Controller in Fortinet SD-WAN provides centralized end-to-end visibility into application usage, bandwidth consumption, and WAN link performance across all connected sites. It collects data from branch devices, WAN Path Monitor, Application Control, and other SD-WAN components to give administrators a holistic view of network performance and user activity. This visibility allows network teams to monitor trends, detect anomalies, enforce policies, and make informed decisions regarding routing, prioritization, and capacity planning. By consolidating insights into a single interface, the SD-WAN Controller reduces operational complexity, improves troubleshooting efficiency, and ensures consistent policy enforcement across geographically dispersed sites. Administrators can analyze bandwidth usage per application, identify underperforming WAN links, and verify SLA compliance from the controller, enabling proactive network management and enhanced application performance.
WAN Path Monitor measures the performance of individual WAN links in real-time, collecting metrics such as latency, jitter, packet loss, and throughput. While it provides critical insights into link quality, it does not consolidate information across multiple sites or provide centralized visibility for overall WAN performance. WAN Path Monitor serves as a source of data for the SD-WAN Controller but lacks the reporting and analytical capabilities necessary for end-to-end visibility.
Application Control identifies and classifies application traffic, providing visibility into bandwidth usage and enabling prioritization policies. While it offers insights into application-level traffic patterns, it does not provide a network-wide view of performance across multiple sites or correlate data from multiple WAN links. Application Control supports decision-making for traffic prioritization but relies on the SD-WAN Controller for comprehensive visibility and policy enforcement.
Path Conditioning improves the reliability of individual WAN links by mitigating packet loss, jitter, and latency. Although it enhances the quality of traffic for real-time applications, it does not provide end-to-end visibility or centralized reporting. Path Conditioning operates at the link level to stabilize traffic and cannot aggregate metrics across multiple sites or applications.
The SD-WAN Controller is the correct answer because it consolidates data from WAN Path Monitors, Application Control, and branch devices to provide a complete view of application usage, bandwidth consumption, and WAN performance. Unlike WAN Path Monitor, which focuses on individual links, Application Control, which focuses on traffic classification, or Path Conditioning, which stabilizes links, the controller delivers centralized visibility for the entire network. This capability allows administrators to proactively manage resources, optimize WAN performance, enforce SLA compliance, and maintain a consistent user experience across multiple branches and cloud connections. By providing analytics, reporting, and dashboards, the SD-WAN Controller ensures that network decisions are data-driven and aligned with business objectives, supporting efficient operations and reliable delivery of critical applications.
Question 36
Which Fortinet SD-WAN function allows for traffic duplication across two WAN links to ensure no packet loss for critical applications?
A) Path Conditioning
B) Forward Error Correction (FEC)
C) WAN Aggregation
D) Link Load Balancing
Answer: B) Forward Error Correction (FEC)
Explanation:
Forward Error Correction (FEC) in Fortinet SD-WAN enables traffic duplication or the transmission of redundant data across multiple WAN links to ensure no packet loss for critical applications. FEC works by sending additional parity packets along with the original traffic, allowing the receiving end to reconstruct lost packets without requiring retransmission. This is particularly valuable for latency-sensitive and high-priority applications such as VoIP, video conferencing, or financial trading platforms, where even minimal packet loss can impact user experience or operational effectiveness. By proactively correcting errors in transit, FEC provides reliability over unstable or lossy WAN connections and ensures that critical data reaches its destination without degradation.
Path Conditioning stabilizes WAN links by mitigating jitter, latency, and packet loss. It improves the quality of a link but does not create redundant data streams to recover lost packets. While Path Conditioning enhances performance for real-time applications, it relies on stabilizing the existing flow rather than transmitting duplicate information for loss recovery.
WAN Aggregation combines multiple WAN links into a single logical path to increase bandwidth and provide redundancy. Although aggregation improves throughput and can support multiple flows, it does not duplicate traffic for error correction. Aggregation focuses on capacity rather than reliability at the packet level, so it cannot guarantee lossless delivery for critical applications.
Link Load Balancing distributes traffic across multiple WAN links to optimize bandwidth utilization. While it prevents congestion and improves resource utilization, it does not ensure packet recovery or duplication for critical flows. Load balancing splits traffic rather than providing error correction or redundant data streams for mission-critical applications.
Forward Error Correction (FEC) is the correct answer because it proactively duplicates or adds parity information to packets to prevent packet loss for critical applications. Unlike Path Conditioning, which stabilizes existing flows, WAN Aggregation, which increases bandwidth, or Link Load Balancing, which distributes traffic, FEC ensures that lost packets can be reconstructed at the receiving end, maintaining the integrity and performance of sensitive applications. FEC is essential in Fortinet SD-WAN for latency-sensitive traffic and high-priority services, providing reliability and uninterrupted delivery across multiple WAN links and supporting consistent quality for voice, video, and critical business applications.
Question 37
Which Fortinet SD-WAN feature enables real-time rerouting of application traffic based on current WAN link performance and business priorities?
A) Application Steering
B) SLA-Based Routing
C) Path Conditioning
D) Link Load Balancing
Answer: A) Application Steering
Explanation:
Application Steering in Fortinet SD-WAN enables real-time rerouting of application traffic based on current WAN link performance, application type, and business priorities. It continuously monitors metrics such as latency, jitter, packet loss, and throughput on all available WAN links. Using this information, Application Steering can dynamically direct traffic to the optimal path for each application, ensuring that critical business applications like VoIP, video conferencing, or cloud-based ERP systems maintain high performance and reliability. By aligning traffic routing with business priorities, administrators can ensure that essential applications are prioritized over non-critical traffic. This functionality provides a proactive method for maintaining service quality, improving user experience, and maximizing the efficiency of available WAN resources. Application Steering allows enterprises to adapt quickly to changing network conditions and optimize the flow of application traffic in real time.
SLA-Based Routing monitors WAN links against predefined performance thresholds, such as latency, jitter, and packet loss. While it can reroute traffic if a link does not meet these thresholds, SLA-Based Routing does not inherently consider business priorities or make granular per-application routing decisions. It focuses on ensuring that links meet minimum performance criteria rather than dynamically steering individual applications based on both performance and priority.
Path Conditioning improves link reliability by mitigating packet loss, jitter, and latency on individual WAN links. While it helps maintain performance for real-time applications, it does not perform dynamic rerouting of traffic based on current conditions or application requirements. Path Conditioning stabilizes traffic flows rather than actively making routing decisions.
Link Load Balancing distributes traffic across multiple WAN links according to predefined weights, round-robin, or other load distribution algorithms. While load balancing improves bandwidth utilization, it does not prioritize traffic based on application type or business priority, nor does it make real-time rerouting decisions based on current performance metrics. It focuses on overall network efficiency rather than application-specific optimization.
Application Steering is the correct answer because it combines real-time link monitoring, application intelligence, and business priorities to dynamically reroute traffic. Unlike SLA-Based Routing, which focuses solely on meeting link thresholds, Path Conditioning, which stabilizes links, or Link Load Balancing, which distributes traffic evenly, Application Steering ensures that high-priority applications consistently use the best available paths. This feature improves user experience for critical services, enhances WAN resource utilization, and allows enterprises to maintain predictable application performance across multiple sites. By continuously evaluating link conditions and dynamically steering application traffic, it ensures that essential applications remain performant even during network congestion or link degradation, providing a robust solution for modern enterprise WAN environments.
Question 38
Which Fortinet SD-WAN feature increases bandwidth for high-volume applications by combining multiple WAN links into a single logical path?
A) WAN Aggregation
B) Application Steering
C) SLA-Based Routing
D) Path Conditioning
Answer: A) WAN Aggregation
Explanation:
WAN Aggregation in Fortinet SD-WAN allows multiple WAN links to be logically combined into a single interface, increasing overall bandwidth for high-volume applications. This feature is particularly useful for applications such as large file transfers, cloud backups, video streaming, or high-volume data replication. By aggregating multiple links, traffic can be transmitted across all available paths simultaneously, maximizing throughput and improving network efficiency. WAN Aggregation also provides redundancy, as traffic can continue flowing if one of the aggregated links fails. This ensures uninterrupted service and better utilization of all available WAN resources. Enterprises benefit from increased capacity without requiring additional complex configurations or separate links for high-bandwidth applications.
Application Steering dynamically directs traffic based on application type, business priorities, and link performance. While it optimizes application paths for performance and reliability, it does not physically combine multiple links to increase total bandwidth. Steering improves latency-sensitive application performance but does not create a logical aggregation of links to support higher throughput for large-volume applications.
SLA-Based Routing monitors WAN links against defined performance thresholds such as latency, jitter, and packet loss. It reroutes traffic when links fail to meet these criteria, but does not increase total bandwidth by combining multiple connections. SLA-Based Routing ensures application quality by selecting the best available link, but does not merge links to accommodate high-volume traffic.
Path Conditioning enhances the stability of individual WAN links by addressing packet loss, jitter, and latency. While it improves the quality of a specific link, it does not increase overall bandwidth or merge multiple links. Path Conditioning focuses on maintaining a steady flow of traffic rather than expanding capacity for high-bandwidth applications.
WAN Aggregation is the correct answer because it provides a mechanism to combine multiple WAN links into a single logical path, enabling high-volume applications to utilize the total available bandwidth. Unlike Application Steering, which optimizes routing, SLA-Based Routing, which ensures links meet performance thresholds, or Path Conditioning, which stabilizes links, WAN Aggregation directly addresses the need for increased throughput and redundancy. By leveraging multiple links simultaneously, WAN Aggregation maximizes efficiency, reduces congestion, and ensures that bandwidth-intensive applications can operate without performance degradation. Enterprises can achieve scalable performance and resilience across the WAN, supporting cloud adoption, real-time collaboration, and other critical high-bandwidth applications.
Question 39
Which Fortinet SD-WAN feature compensates for packet loss and jitter to maintain high-quality real-time application performance?
A) Path Conditioning
B) SLA-Based Routing
C) Application Steering
D) WAN Aggregation
Answer: A) Path Conditioning
Explanation:

It employs techniques such as packet buffering, Forward Error Correction (FEC), and retransmission mechanisms to stabilize traffic, particularly for latency-sensitive applications like VoIP, video conferencing, and live streaming. Path Conditioning ensures that even if a WAN link experiences instability or packet loss, the end-to-end performance remains consistent and reliable. By mitigating variations in packet delivery and correcting errors in transit, it prevents choppy audio, frozen video, and other disruptions that degrade user experience. This feature is critical for enterprises relying on real-time applications, where even minor network impairments can significantly impact productivity and service quality.
SLA-Based Routing monitors WAN links against predefined thresholds for latency, jitter, and packet loss, and reroutes traffic when a link fails to meet performance criteria. While it ensures traffic is sent over links that meet SLA requirements, it does not actively stabilize or correct traffic on a degraded link. SLA-Based Routing is reactive, making routing decisions based on current performance rather than improving the link’s inherent reliability.
Application Steering dynamically directs traffic based on application type, business priority, and real-time link performance. Although it optimizes routing decisions and ensures critical applications follow the best-performing paths, it does not stabilize or compensate for packet loss and jitter on a particular link. Steering relies on stable paths to maintain performance and does not implement error correction mechanisms.
WAN Aggregation combines multiple WAN links into a single logical path, increasing overall bandwidth and providing redundancy. While aggregation can help with high-volume traffic and resiliency, it does not address packet loss or jitter on individual links. Aggregation optimizes capacity but does not inherently improve real-time application quality on an unstable link.
Path Conditioning is the correct answer because it specifically compensates for packet loss, jitter, and latency, maintaining high-quality performance for real-time applications. Unlike SLA-Based Routing, which reroutes traffic, Application Steering, which optimizes paths, or WAN Aggregation, which increases bandwidth, Path Conditioning stabilizes existing links. It ensures smooth, uninterrupted delivery for latency-sensitive applications by correcting network impairments and smoothing packet flows. This feature is essential in Fortinet SD-WAN deployments where consistent performance for voice, video, and other real-time services is a critical business requirement. By proactively addressing link-level issues, Path Conditioning ensures predictable performance and reliable user experience across enterprise WAN environments.
Question 40
Which Fortinet SD-WAN feature allows administrators to restrict or prioritize application traffic based on business requirements and user-defined policies?
A) Application Control
B) Application Steering
C) Path Conditioning
D) WAN Aggregation
Answer: A) Application Control
Explanation:
Application Control in Fortinet SD-WAN enables administrators to restrict, prioritize, or shape application traffic based on business requirements and user-defined policies. It identifies and classifies applications traversing the WAN by using deep packet inspection and other identification mechanisms. Once applications are classified, administrators can apply policies to ensure that critical applications, such as VoIP, video conferencing, ERP systems, or cloud-hosted services, receive priority bandwidth and optimal routing. Lower-priority applications, like software updates or recreational traffic, can be restricted or throttled to prevent them from impacting mission-critical operations. This granular control over application traffic ensures that network resources are allocated efficiently and that business priorities are consistently enforced across all branch locations. Application Control also provides insights into application usage patterns, helping administrators adjust policies to maintain performance, reduce congestion, and optimize WAN resource utilization.
Application Steering dynamically routes traffic over the best-performing WAN link based on link performance, application type, and business priority. While it directs traffic intelligently, it does not allow administrators to enforce bandwidth restrictions or prioritize traffic according to user-defined policies. Steering focuses on path selection rather than controlling the allocation of resources at the application level.
Path Conditioning stabilizes WAN links by mitigating packet loss, jitter, and latency. Although it ensures consistent performance for latency-sensitive applications, it does not enforce traffic restrictions or prioritization policies. Path Conditioning maintains link quality rather than controlling traffic allocation or applying business-specific rules.
WAN Aggregation combines multiple WAN links into a single logical path to increase available bandwidth and provide redundancy. While it enhances overall throughput and resiliency, it does not differentiate between applications or enforce prioritization rules. Aggregation maximizes link utilization but does not provide application-specific control or policy enforcement.
Application Control is the correct answer because it provides the tools to identify, classify, restrict, and prioritize application traffic based on business requirements and user-defined policies. Unlike Application Steering, which optimizes routing, Path Conditioning, which stabilizes links, or WAN Aggregation, which increases capacity, Application Control ensures that critical applications consistently receive the resources they need. By enabling administrators to allocate bandwidth effectively, restrict non-essential traffic, and enforce policies consistently across the network, Application Control improves user experience, maintains SLA compliance, and optimizes the performance of mission-critical services across multiple WAN connections. This feature supports predictable network behavior, resource efficiency, and alignment with organizational priorities.

C) Application Steering
D) Path Conditioning
Answer: A) WAN Path Monitor
Explanation:
WAN Path Monitor is a Fortinet SD-WAN feature that continuously monitors the quality of WAN links by collecting metrics such as latency, jitter, packet loss, and throughput. This real-time monitoring provides critical insights into the current performance and health of each WAN connection. The data collected by WAN Path Monitor enables informed routing decisions by identifying which links are suitable for latency-sensitive, jitter-sensitive, or high-priority applications. By measuring performance at regular intervals, WAN Path Monitor ensures that SD-WAN can proactively respond to changes in link quality, preventing performance degradation for critical applications. This monitoring capability also supports SLA enforcement, helping administrators verify that WAN links meet predefined service levels for different types of traffic. WAN Path Monitor forms the foundation for intelligent SD-WAN routing and prioritization decisions, providing the quantitative data required for optimizing application performance and maintaining predictable network behavior.
SLA-Based Routing reroutes traffic based on predefined performance thresholds, such as latency, jitter, and packet loss. While it acts on performance data, SLA-Based Routing does not collect or measure link metrics itself. Instead, it relies on inputs from monitoring components like WAN Path Monitor to make routing decisions that ensure compliance with service levels.
Application Steering directs traffic based on application type, business priority, and link performance. Although it optimizes application paths and ensures critical traffic uses the best-performing links, it does not collect WAN link performance metrics independently. Steering decisions depend on accurate and up-to-date link data provided by components such as the WAN Path Monitor.
Path Conditioning stabilizes traffic on a WAN link by mitigating packet loss, jitter, and latency. While it improves the quality of individual links, it does not measure or provide performance metrics for WAN links. Path Conditioning operates at the link level to maintain consistent traffic flow rather than providing quantitative monitoring data for routing decisions.
WAN Path Monitor is the correct answer because it collects real-time WAN link quality metrics, enabling SD-WAN components to make informed routing and prioritization decisions. Unlike SLA-Based Routing, which acts on thresholds, Application Steering, which executes routing decisions, or Path Conditioning, which stabilizes links, WAN Path Monitor provides the critical measurement and monitoring capabilities that form the basis for intelligent network management. By continuously assessing latency, jitter, packet loss, and throughput, WAN Path Monitor allows enterprises to maintain predictable application performance, enforce SLAs, and optimize traffic distribution across multiple WAN links. This ensures that high-priority applications receive optimal paths while providing administrators with visibility and control over the health of the entire network.
Question 42
Which Fortinet SD-WAN function provides automatic failover to a secondary WAN link when the primary link fails?
A) SLA-Based Routing
B) WAN Aggregation
C) Path Conditioning
D) Application Steering
Answer: A) SLA-Based Routing
Explanation:
SLA-Based Routing in Fortinet SD-WAN provides automatic failover to a secondary WAN link when the primary link fails or does not meet predefined performance thresholds. Administrators define thresholds for metrics such as latency, jitter, and packet loss for each application or traffic flow. When the primary WAN link experiences degradation or complete failure, SLA-Based Routing automatically reroutes traffic to a backup or secondary link that meets the required performance standards. This ensures continuity of service for critical applications, maintaining user experience and preventing downtime for services such as VoIP, video conferencing, ERP systems, and cloud-hosted applications. Automatic failover reduces the need for manual intervention, enabling high availability and resilience across distributed networks. By integrating real-time monitoring and proactive rerouting, SLA-Based Routing ensures that business-critical traffic continues to flow efficiently even during network outages or link performance degradation.
WAN Aggregation combines multiple WAN links into a single logical path to increase total bandwidth and provide redundancy. While it improves throughput and provides redundancy at a capacity level, it does not dynamically reroute traffic based on link failures or SLA violations. Aggregation ensures availability through combined resources, but does not perform per-application failover based on performance thresholds.
Path Conditioning stabilizes individual WAN links by mitigating packet loss, jitter, and latency. It improves the quality of existing paths but does not provide automatic rerouting to an alternative WAN link in case of failure. Path Conditioning enhances performance on a given link rather than implementing failover mechanisms.
Application Steering directs traffic over the best-performing path based on real-time link performance and business priorities. While it optimizes routing decisions, it does not inherently provide failover based on predefined SLA thresholds. Steering may reroute traffic when paths degrade, but it relies on SLA-Based Routing for automatic enforcement of thresholds and failover to backup links.
SLA-Based Routing is the correct answer because it ensures automatic failover to secondary WAN links when the primary link fails or underperforms. Unlike WAN Aggregation, which combines bandwidth, Path Conditioning, which stabilizes traffic, or Application Steering, which optimizes path selection, SLA-Based Routing proactively monitors performance thresholds and reroutes traffic to maintain service continuity. This capability provides high availability, predictable performance for critical applications, and seamless user experience across multi-branch or cloud-connected enterprise networks. Automating failover reduces operational complexity, minimizes downtime, and ensures resilient WAN operations in dynamic network conditions.
Question 43
Which Fortinet SD-WAN feature ensures that real-time applications like VoIP and video maintain performance even over lossy WAN links?
A) Path Conditioning
B) SLA-Based Routing
C) WAN Aggregation
D) Application Steering
Answer: A) Path Conditioning
Explanation:
Path Conditioning in Fortinet SD-WAN ensures that real-time applications such as VoIP and video maintain consistent performance even over lossy or degraded WAN links. Path Conditioning works by compensating for network impairments such as packet loss, jitter, and latency through techniques including buffering, Forward Error Correction (FEC), and packet sequence management. These mechanisms enable the network to recover or mask lost packets, smooth variations in packet delivery, and maintain a consistent stream of data to the receiving end. For latency-sensitive and jitter-sensitive applications, even minor packet loss can lead to choppy audio, frozen video, or poor-quality conferencing sessions. Path Conditioning mitigates these effects proactively, ensuring that the end-user experience remains high quality. This feature is especially important in enterprise environments where mission-critical communication tools rely on reliable delivery over multiple WAN links, some of which may have varying performance characteristics. By improving traffic quality without requiring changes to the application itself, Path Conditioning enhances the reliability of the entire network for real-time communication.
SLA-Based Routing monitors WAN links against predefined thresholds for metrics such as latency, jitter, and packet loss. While it can reroute traffic if a link fails to meet performance requirements, it does not actively stabilize the link or correct errors on the existing path. SLA-Based Routing is reactive, ensuring that traffic uses a compliant link but does not directly compensate for impairments on a single link. It relies on the availability of alternative paths rather than enhancing the quality of the path in use.
WAN Aggregation combines multiple WAN links into a single logical path to increase overall bandwidth and provide redundancy. While this can improve capacity and throughput, it does not address packet loss, jitter, or latency issues on individual links. Aggregation is designed for high-volume traffic rather than stabilizing real-time application performance, so it cannot guarantee quality for latency-sensitive applications if the underlying links are lossy.
Application Steering directs traffic based on application type, business priority, and link performance. Although it ensures that high-priority applications follow the optimal path, it does not correct network impairments on a link. Steering relies on the existence of multiple WAN paths and performance monitoring to make routing decisions, but it cannot mitigate packet loss or jitter on a degraded link. Its primary function is intelligent path selection rather than error compensation or stabilization.
Path Conditioning is the correct answer because it actively compensates for packet loss, jitter, and latency to ensure high-quality performance for real-time applications. Unlike SLA-Based Routing, which reroutes traffic when thresholds are not met, WAN Aggregation, which increases capacity, or Application Steering, which optimizes routing, Path Conditioning stabilizes the existing link itself. By applying buffering, error correction, and sequence management techniques, it preserves audio and video quality even under challenging network conditions. This ensures reliable delivery of mission-critical real-time applications, minimizes disruptions, and maintains a consistent user experience across multiple branches or cloud environments. Path Conditioning is an essential component of Fortinet SD-WAN for enterprises that require predictable, high-quality performance for sensitive applications.
Question 44
Which Fortinet SD-WAN capability allows administrators to view trends in WAN performance, application usage, and traffic patterns over time?
A) SD-WAN Controller
B) WAN Path Monitor
C) Application Control
D) Path Conditioning
Answer: A) SD-WAN Controller
Explanation:
The SD-WAN Controller in Fortinet SD-WAN provides centralized visibility into WAN performance, application usage, and traffic patterns over time. It collects data from WAN Path Monitors, Application Control modules, branch devices, and other SD-WAN components to generate detailed insights into historical and real-time network conditions. By analyzing trends in latency, jitter, packet loss, bandwidth utilization, and application traffic, administrators can make informed decisions regarding capacity planning, policy adjustments, and network optimization. The controller provides dashboards, analytics, and reporting tools that allow IT teams to monitor overall network health, identify recurring issues, and measure SLA compliance. This long-term visibility is crucial for enterprises managing multiple sites or cloud connections, as it enables proactive planning, helps avoid performance bottlenecks, and supports business continuity. Through the SD-WAN Controller, administrators can correlate application behavior with WAN link performance, ensuring predictable user experiences and effective management of network resources.
WAN Path Monitor measures the performance of individual WAN links in real time, providing metrics such as latency, jitter, packet loss, and throughput. While it collects valuable data, it does not consolidate trends across multiple sites or provide long-term historical analytics. WAN Path Monitor is primarily a monitoring tool for individual links rather than a centralized platform for network-wide trend analysis.
Application Control identifies and classifies application traffic, allowing administrators to enforce prioritization policies and manage bandwidth. Although it provides visibility into application usage at a specific point in time, it does not aggregate historical data or generate trend reports across the network. Application Control focuses on real-time traffic management rather than long-term analytics.
Path Conditioning stabilizes WAN links by mitigating packet loss, jitter, and latency. While it improves performance for real-time applications, it does not provide visibility into network trends or traffic patterns over time. Path Conditioning enhances link quality but does not generate reports or allow administrators to analyze historical performance data.
The SD-WAN Controller is the correct answer because it provides comprehensive, network-wide visibility and analytics for WAN performance, application usage, and traffic patterns over time. Unlike WAN Path Monitor, which measures individual links, Application Control, which focuses on real-time traffic, or Path Conditioning, which stabilizes links, the SD-WAN Controller consolidates data, analyzes trends, and presents actionable insights. This functionality allows administrators to optimize WAN resources, maintain SLA compliance, anticipate potential issues, and support long-term planning. By enabling centralized monitoring and historical analysis, the SD-WAN Controller ensures that enterprises can make data-driven decisions to maintain application performance, improve user experience, and manage complex multi-site networks effectively.
Question 45
Which Fortinet SD-WAN feature allows high-priority application traffic to use the best-performing WAN path while non-critical traffic uses alternate paths?
A) Application Steering
B) SLA-Based Routing
C) Path Conditioning
D) WAN Aggregation
Answer: A) Application Steering
Explanation:
Application Steering in Fortinet SD-WAN allows high-priority application traffic to use the best-performing WAN path while lower-priority or non-critical traffic is routed through alternate, less optimal paths. It continuously monitors metrics such as latency, jitter, packet loss, and bandwidth utilization across all available WAN links. Based on real-time conditions and administrator-defined business priorities, Application Steering dynamically directs traffic to ensure that critical applications, such as VoIP, video conferencing, ERP systems, or cloud-hosted services, maintain optimal performance. Non-critical traffic, like email, file transfers, or background updates, is steered to links that may have lower performance but sufficient capacity, ensuring efficient use of available resources. This approach allows enterprises to maximize WAN utilization while maintaining service levels for high-priority applications. By providing granular control over traffic paths and prioritization, Application Steering improves user experience, reduces congestion, and supports predictable application performance across multiple branch offices and cloud connections.
SLA-Based Routing monitors WAN links against predefined thresholds for latency, jitter, and packet loss. While it can reroute traffic based on performance, it does not inherently differentiate traffic by business priority or dynamically assign high-priority applications to the best-performing links while steering lower-priority traffic elsewhere. SLA-Based Routing focuses on maintaining minimum performance thresholds rather than prioritizing traffic hierarchically.
Path Conditioning improves the quality of individual WAN links by compensating for packet loss, jitter, and latency. Although it enhances the performance of a specific link, it does not direct high-priority traffic to the best-performing path or dynamically manage routing based on business priorities. Path Conditioning stabilizes links but does not implement traffic steering decisions.
WAN Aggregation combines multiple WAN links into a single logical path to increase bandwidth and provide redundancy. While aggregation can improve capacity, it does not prioritize traffic or differentiate paths for high- and low-priority applications. Aggregation treats all traffic equally and does not implement dynamic steering based on real-time performance or business priorities.
Application Steering is the correct answer because it ensures that high-priority applications use the best-performing WAN links while non-critical traffic is routed through alternate paths. Unlike SLA-Based Routing, which focuses on minimum thresholds, Path Conditioning, which stabilizes individual links, or WAN Aggregation, which increases bandwidth, Application Steering combines real-time monitoring, performance optimization, and business-priority rules to deliver predictable, high-quality application performance. By dynamically aligning traffic paths with both network conditions and business objectives, it maximizes efficiency, enhances user experience, and ensures critical services remain uninterrupted across multi-branch enterprise networks.
