SLA-Based Application Profiles are especially beneficial in hybrid WAN environments where multiple transport links of varying quality exist, including broadband, MPLS, and LTE connections. The profiles allow administrators to differentiate applications based on business priority, ensuring high-value applications receive priority routing while best-effort applications utilize secondary paths, maximizing the efficiency of the WAN infrastructure. When a link fails to meet the SLA for a specific application profile, traffic is rerouted automatically to healthier links without interrupting ongoing sessions. This proactive traffic management reduces downtime, improves user experience, and enhances operational efficiency by minimizing the need for manual adjustments. SLA-Based Application Profiles work seamlessly with session-aware steering, autonomous self-healing, and performance-based path selection, enabling end-to-end SD-WAN optimization. By defining application-specific thresholds, administrators can enforce consistent policies across multiple branches, ensuring predictable performance for distributed enterprises. Historical performance data collected from SLA probes can be used to refine profiles and anticipate network issues, improving long-term SLA compliance. This approach aligns routing decisions with business priorities, reduces the risk of performance degradation for critical workloads, and ensures that high-priority applications always receive the best possible path. SLA-Based Application Profiles provide granular control over traffic management, enhancing resiliency and reliability while simplifying operational management in complex SD-WAN deployments. By proactively steering applications based on SLA thresholds, enterprises can deliver consistent, high-quality service to end users and maintain efficient utilization of all WAN resources.
Static Route Assignment relies on fixed paths for traffic and cannot dynamically adjust to link degradation or application performance requirements, which risks SLA violations.
Interface Weighting distributes traffic according to predefined ratios without considering SLA thresholds or application priorities, potentially affecting critical applications during congestion or link degradation.
Manual Path Configuration requires administrators to intervene to reroute traffic, which is reactive and labor-intensive, limiting operational efficiency and responsiveness to real-time network conditions.
SLA-Based Application Profiles are correct because they allow administrators to define application-specific performance thresholds, monitor links in real time, and dynamically steer traffic to maintain SLA compliance, optimizing application delivery and user experience.
Question 119
Which Fortinet SD-WAN capability ensures that branch offices can maintain traffic forwarding and service continuity even if the connection to the central hub is lost?
A) Autonomous Self-Healing
B) Centralized Orchestration
C) Manual Route Override
D) Fixed Interface Routing
Answer: A) Autonomous Self-Healing
Explanation:
Autonomous Self-Healing in Fortinet SD-WAN enables branch offices to operate independently and continue forwarding traffic even when connectivity to the central controller or hub is unavailable. This feature ensures uninterrupted delivery of critical services, including VoIP, video conferencing, cloud applications, and inter-branch communications, by relying on locally stored routing and security policies. When a WAN link degrades or fails, the SD-WAN engine evaluates link quality metrics such as latency, jitter, packet loss, and bandwidth availability to determine the optimal paths for traffic, rerouting flows dynamically while preserving active sessions. Session-aware steering ensures that ongoing sessions continue seamlessly during rerouting, preventing dropped calls, interrupted file transfers, or degraded application performance. Administrators can predefine failover policies, bandwidth allocations, and path preferences, enabling branches to maintain service continuity autonomously. This reduces operational complexity and reliance on central management, particularly in distributed hybrid WAN environments with multiple transport types like MPLS, broadband, and LTE. Autonomous Self-Healing integrates with SLA-based monitoring, application-aware routing, and performance-based path selection to provide intelligent traffic management and predictable application delivery across all branch locations. By maintaining local control over routing and policies, branches can sustain business-critical operations even during central controller outages. Enterprises benefit from improved resiliency, consistent SLA compliance, and minimized downtime, ensuring a seamless user experience across geographically dispersed sites. The feature also supports automated decision-making and real-time traffic optimization, reducing manual intervention and operational overhead. Autonomous Self-Healing is essential for distributed organizations that require high availability and reliable connectivity for critical workloads. It ensures that branches can adapt to changing network conditions, maintain service continuity, and leverage all available WAN resources effectively. By enabling branches to forward traffic independently, this capability enhances SD-WAN reliability, resilience, and operational efficiency, making it a cornerstone of Fortinet’s SD-WAN solution.
Centralized Orchestration depends on connectivity to the central hub to enforce policies and manage routing. Loss of connection can disrupt branch operations and lead to service interruptions.
Manual Route Override requires administrators to manually reroute traffic during WAN issues, which is reactive, labor-intensive, and prone to errors, making it unsuitable for maintaining seamless branch operations.
Fixed Interface Routing binds traffic to specific interfaces regardless of link quality. It does not provide dynamic rerouting, SLA compliance, or autonomous operation, leaving branches vulnerable to outages.
Autonomous Self-Healing is correct because it allows branches to enforce local policies, dynamically reroute traffic, maintain active sessions, and ensure uninterrupted application delivery during central hub outages, improving operational efficiency and resiliency.
Question 120
Which Fortinet SD-WAN mechanism allows seamless rerouting of active sessions when a WAN link underperforms or fails?
A) Session-Aware Steering
B) Static Route Assignment
C) Interface Preference Rules
D) Lowest Cost Path
Answer: A) Session-Aware Steering
Explanation:
Session-Aware Steering in Fortinet SD-WAN ensures that active sessions are maintained without interruption when a WAN link underperforms or fails. Unlike traditional routing approaches that may drop active sessions during failover events, this feature continuously monitors session states and WAN link performance in real time. Metrics such as latency, jitter, packet loss, and bandwidth availability are assessed to determine the most suitable path for each flow. If a currently used path fails to meet SLA thresholds or becomes unavailable, traffic is seamlessly rerouted to an alternative link while preserving the active session, preventing disruptions to VoIP calls, video conferences, cloud applications, and interactive services. Session-Aware Steering integrates with SLA-based monitoring, application-aware routing, and performance-based path selection to ensure intelligent traffic management and predictable application performance across hybrid WAN environments. Administrators can define routing preferences, bandwidth allocations, and failover priorities to prioritize high-value or latency-sensitive applications while allowing best-effort traffic to use secondary paths. This proactive approach reduces operational intervention, ensures SLA compliance, and enhances user experience by avoiding session drops or degraded service. It is particularly valuable in distributed enterprises with multiple branch sites and hybrid WAN links, as it dynamically adapts to varying link conditions and network congestion. By preserving active sessions, Session-Aware Steering enables continuous productivity, reliable service delivery, and seamless cloud application access.
