Question 91

Which Fortinet SD-WAN feature allows administrators to assign different SLA thresholds and routing preferences based on application type or business importance?

A) Application-Aware Routing
B) Static Route Policies
C) Interface-Based Load Balancing
D) Manual Path Selection

Answer:  A) Application-Aware Routing

Explanation:

Application-Aware Routing in Fortinet SD-WAN provides administrators the ability to assign specific SLA thresholds, routing preferences, and priorities based on the type or business criticality of each application. This feature ensures that high-priority applications, such as voice, video conferencing, ERP, or SaaS workloads, are delivered over WAN paths that meet performance criteria for latency, jitter, packet loss, and throughput. Application-Aware Routing continuously monitors link performance metrics using SLA probes and other real-time telemetry to make intelligent traffic steering decisions. By classifying applications and applying defined policies, traffic is dynamically routed over the most suitable path while ensuring that less critical applications are handled on lower-priority links or best-effort paths. This mechanism improves user experience, reduces downtime, and optimizes hybrid WAN utilization, balancing the competing needs of critical and non-critical traffic. Application-Aware Routing also supports session continuity through session-aware steering, ensuring that active sessions remain uninterrupted even during WAN link degradation. Administrators can define failover preferences, traffic prioritization, and bandwidth allocation policies per application or application group, creating an intelligent, SLA-driven environment. This approach reduces operational complexity, eliminates manual routing interventions, and ensures consistency across distributed branches and multiple WAN transports. Application-Aware Routing is particularly effective in hybrid WAN scenarios where broadband, MPLS, and LTE links vary in quality, providing a resilient, performance-optimized, and business-aligned SD-WAN deployment.

Static Route Policies require administrators to predefine paths for traffic based on fixed criteria. While they can be used to prioritize certain applications or subnets, they do not dynamically adjust routing based on real-time link metrics or SLA thresholds. Static policies are inflexible and do not respond to performance degradation or varying network conditions.

Interface-Based Load Balancing distributes traffic across available WAN interfaces according to predefined weights or ratios. While it can optimize bandwidth utilization, it does not consider application requirements or performance metrics. Traffic may traverse suboptimal paths for latency-sensitive applications, negatively impacting user experience.

Manual Path Selection requires network administrators to intervene whenever a routing adjustment is necessary. This approach is not scalable, cannot adapt in real time, and risks inconsistent routing across multiple branches. It increases operational burden and does not guarantee SLA adherence for critical applications.

Application-Aware Routing is correct because it enables intelligent, SLA-driven, and application-focused traffic management. By continuously monitoring WAN link performance and aligning routing with business priorities, it ensures that critical applications receive optimal delivery while maintaining efficient use of network resources. This feature is central to Fortinet SD-WAN’s ability to provide a resilient, performance-oriented, and business-aligned WAN architecture, enhancing user experience and reducing operational complexity.

It ensures that high-priority applications are consistently delivered over optimal paths, maintains SLA compliance, and enhances hybrid WAN efficiency while reducing operational complexity and maintaining resilient connectivity across distributed networks.

Question 104

Which Fortinet SD-WAN mechanism proactively monitors WAN links and reroutes traffic if performance metrics fall below SLA thresholds?

A) SLA-Based Probes
B) Static Default Routing
C) Manual Ping Tests
D) Interface Preference Rules

Answer:  A) SLA-Based Probes

Explanation:

SLA-Based Probes in Fortinet SD-WAN are a proactive monitoring mechanism designed to continuously assess WAN link performance and trigger traffic rerouting when metrics fall below predefined SLA thresholds. These probes generate synthetic traffic that simulates application flows to measure key metrics such as latency, jitter, and packet loss. By evaluating links in real time, the SD-WAN engine can determine whether a particular path is suitable for high-priority or latency-sensitive applications, such as VoIP, video conferencing, ERP, or SaaS workloads. When a link fails to meet the SLA criteria for a particular application or traffic class, traffic is automatically redirected to the next best-performing path without disrupting ongoing sessions, preserving service quality and user experience. SLA-Based Probes operate continuously and independently of live application traffic, ensuring accurate monitoring without interfering with production flows. This capability is critical for maintaining predictable application performance and ensuring that business-critical traffic receives optimal WAN treatment. SLA-Based Probes integrate closely with other SD-WAN features such as performance-based path selection, application-aware routing, session-aware steering, and autonomous self-healing to maintain seamless connectivity and prevent service disruption. They allow administrators to define distinct SLAs for different applications, prioritize critical traffic, and optimize hybrid WAN utilization, improving operational efficiency and reducing manual intervention. By proactively detecting underperforming links before they impact end users, SLA-Based Probes enable dynamic traffic steering and improve SLA compliance across distributed branch environments. Enterprises benefit from higher reliability, improved application performance, and operational simplicity, as traffic rerouting is automated and aligned with business priorities. Continuous monitoring through SLA-Based Probes supports capacity planning, predictive network maintenance, and historical performance analysis, ensuring that WAN resources are used effectively and business objectives are met. This feature is essential for maintaining resilient, application-aware SD-WAN deployments in complex, multi-branch networks with hybrid WAN connections.

Static Default Routing uses predetermined paths and does not monitor performance metrics. Traffic remains on assigned links regardless of degradation, risking SLA violations and disrupted application performance.

Manual Ping Tests require administrators to initiate tests and provide limited, non-continuous insight into link quality. They cannot trigger automated rerouting based on SLA compliance, limiting operational effectiveness.

Interface Preference Rules prioritize certain paths or interfaces statically. While they influence routing decisions, they do not account for real-time link performance or automatically reroute traffic based on SLA thresholds.

SLA-Based Probes is correct because it actively monitors link performance using synthetic traffic, measures key metrics, and automatically triggers dynamic rerouting when thresholds are not met. It ensures predictable application performance, SLA compliance, and seamless traffic delivery across distributed SD-WAN environments.

Question 105

Which Fortinet SD-WAN strategy ensures that latency-sensitive applications are always routed over the WAN path with the lowest delay?

A) Lowest Latency First
B) Performance-Based Path Selection
C) Static Default Routing
D) Equal-Cost Multi-Path (ECMP)

Answer:  A) Lowest Latency First

Explanation:

Lowest Latency First is a Fortinet SD-WAN strategy designed to ensure that latency-sensitive applications, such as VoIP, video conferencing, and interactive cloud services, are always routed over the WAN path with the lowest measured latency. The SD-WAN engine continuously monitors latency metrics on all available WAN links using SLA probes or real-time telemetry. When the latency on a currently used path exceeds predefined thresholds for a particular application, traffic is dynamically redirected to a lower-latency path, ensuring optimal user experience and minimal disruption for real-time applications. This strategy is essential for time-sensitive communications and workloads where even slight delays can degrade performance, introduce jitter, or disrupt session continuity. Lowest Latency First works in conjunction with session-aware steering to maintain active flows during path changes, ensuring uninterrupted delivery for ongoing sessions. It also integrates with application-aware routing and SLA-based policies, allowing administrators to define latency thresholds per application type and enforce prioritized routing for critical business applications. By consistently steering latency-sensitive traffic over the fastest path, this strategy maintains high-quality service, reduces service interruptions, and optimizes hybrid WAN utilization. Enterprises benefit from improved reliability, predictable application performance, and reduced operational intervention since path selection is automated and aligned with SLA objectives. Lowest Latency First is particularly effective in complex networks with multiple WAN links of varying quality, such as broadband, MPLS, and LTE, because it dynamically adapts routing decisions based on real-time measurements. It ensures that business-critical applications experience minimal delay, supporting productivity, collaboration, and operational efficiency across distributed branch environments. By focusing on latency as the primary performance metric, this strategy guarantees that applications sensitive to delay always receive the best-performing path, providing predictable performance and seamless user experience.

Performance-Based Path Selection evaluates multiple metrics, including latency, jitter, and packet loss, to select the optimal path. While comprehensive, it balances multiple factors rather than prioritizing latency alone, making it slightly less targeted for latency-sensitive workloads.

Static Default Routing uses predetermined paths without considering real-time performance. Traffic remains on assigned links regardless of latency, risking disrupted service for time-sensitive applications.

Equal-Cost Multi-Path (ECMP) distributes traffic across multiple paths of equal routing cost, without evaluating latency or other performance metrics. It cannot guarantee optimal path selection for latency-sensitive applications.

Lowest Latency First is correct because it prioritizes WAN paths with the lowest measured delay, ensuring consistent, high-quality delivery for real-time, latency-sensitive applications. It integrates with session-aware steering and SLA policies to maintain uninterrupted service and optimal performance.
