Static Route Assignment directs traffic along predetermined paths without consideration of real-time WAN performance. This can lead to SLA violations, dropped sessions, and poor application performance during link degradation.
Interface Preference Rules prioritize specific WAN links statically, without monitoring real-time metrics, which may route critical traffic over degraded paths and negatively affect application experience.
Lowest Cost Path selects routes based on administrative or economic criteria rather than live WAN performance, making it unsuitable for ensuring SLA compliance or preserving session continuity.
Performance-Based Path Selection is correct because it continuously monitors WAN link performance, dynamically reroutes traffic based on SLA compliance, preserves active sessions, and ensures optimal delivery of critical applications across hybrid SD-WAN deployments.
Question 134
Which Fortinet SD-WAN mechanism allows branch offices to maintain traffic forwarding independently when the connection to the central controller 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 is designed to allow branch offices to operate independently and continue forwarding traffic even when connectivity to the central controller or management hub is lost. This capability ensures that business-critical applications, such as VoIP, video conferencing, cloud services, and inter-branch communication, remain operational without interruption. When a WAN link fails or central management becomes unavailable, the SD-WAN engine evaluates available WAN links using performance metrics like latency, jitter, packet loss, and bandwidth utilization. Based on these metrics, traffic is dynamically rerouted to healthy links, while session-aware steering ensures ongoing sessions are preserved. This prevents disruptions in voice, video, or cloud-based applications and maintains high-quality user experience. Administrators can define failover policies, bandwidth allocations, and routing preferences to ensure that mission-critical applications continue to receive optimal performance while lower-priority traffic utilizes secondary paths. Autonomous Self-Healing reduces reliance on centralized orchestration, enabling local enforcement of policies and intelligent routing decisions at branch sites. In hybrid WAN environments with multiple transport types such as MPLS, broadband, and LTE, this feature enhances resiliency and guarantees service continuity. SLA-based monitoring and performance-based path selection integrate with Autonomous Self-Healing, providing proactive traffic optimization and ensuring that branches can function independently under varying network conditions. Historical performance data can be analyzed for capacity planning and policy adjustments to anticipate potential issues and improve overall WAN efficiency. This feature minimizes operational complexity, reduces downtime, and allows organizations to maintain predictable application performance across geographically dispersed sites. Enterprises benefit from improved SLA compliance, seamless service delivery, and optimized bandwidth utilization. Autonomous Self-Healing is a cornerstone of Fortinet SD-WAN’s high-availability architecture, enabling resilient, self-sufficient branch operation while maintaining business continuity. By allowing branches to reroute traffic intelligently without central intervention, organizations achieve operational efficiency, consistent application performance, and robust network resiliency even during controller outages or link failures.
Centralized Orchestration relies on a connection to the central controller, and loss of connectivity can disrupt traffic management and policy enforcement at branches, leading to potential SLA violations.
Manual Route Override requires human intervention to reroute traffic, which is reactive, time-consuming, and prone to errors, making it unsuitable for autonomous operation.
Fixed Interface Routing binds traffic to specific interfaces without evaluating link health or performance, preventing dynamic failover or independent branch operation.
Autonomous Self-Healing is correct because it enables branches to continue forwarding traffic independently, enforce local policies, reroute dynamically, and preserve session continuity during central controller outages, ensuring uninterrupted application delivery and operational continuity.
Question 135
Which Fortinet SD-WAN mechanism preserves active sessions during WAN link failover or degradation?
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 is a mechanism that ensures active sessions continue uninterrupted during WAN link failover or performance degradation. In traditional routing, session continuity is not guaranteed when links fail or degrade, leading to dropped VoIP calls, interrupted video conferences, disrupted cloud transactions, or degraded SaaS application performance. Session-Aware Steering continuously monitors the state of active sessions and real-time WAN link metrics, such as latency, jitter, packet loss, and available bandwidth. When a link fails to meet SLA thresholds or becomes unavailable, the SD-WAN engine reroutes traffic to the healthiest alternative path without terminating the active session. This ensures uninterrupted delivery of mission-critical applications, latency-sensitive workloads, and interactive services, preserving end-user experience. The mechanism works in conjunction with SLA-based monitoring, performance-based path selection, and application-aware routing to optimize traffic dynamically and maintain predictable application performance. Administrators can configure routing policies, failover priorities, and bandwidth allocations per session or application type to maintain efficient hybrid WAN utilization. Session-Aware Steering also complements autonomous self-healing, enabling branch offices to make local routing decisions and maintain traffic forwarding even if central controller connectivity is lost. Historical session and link performance data can be leveraged for capacity planning, policy adjustments, and predictive maintenance. This proactive approach reduces operational disruptions, ensures SLA compliance, and provides consistent high-quality application delivery. Enterprises benefit from uninterrupted access to critical applications, optimized WAN resource utilization, and reduced operational overhead. In environments with fluctuating WAN performance, Session-Aware Steering maintains seamless application continuity, enhances resiliency, and improves overall SD-WAN efficiency. By preserving active sessions while dynamically selecting optimal paths, it provides predictable, reliable, and high-performance connectivity across geographically distributed networks. Session-Aware Steering is a core capability of Fortinet SD-WAN that supports business continuity, operational efficiency, and consistent user experience.
Static Route Assignment uses fixed paths and does not preserve active sessions during link failure or degradation, potentially causing service interruptions and SLA violations.
Interface Preference Rules prioritize links statically without evaluating real-time performance or session integrity, risking disruption of active flows during WAN events.
Lowest Cost Path selects routes based on administrative or economic considerations rather than real-time performance or session continuity, which may lead to dropped sessions and degraded application performance.
Session-Aware Steering is correct because it continuously monitors session states and WAN link metrics, reroutes traffic to healthy paths without disruption, and preserves active sessions, ensuring seamless application delivery, SLA compliance, and optimized SD-WAN performance.
