Exam NSE5_SSE_AD-7.6 Topic 2 Question 5 Discussion

According to theSD-WAN 7.6 Core Administratorstudy guide and theFortiOS 7.6 Administration Guide, configuring load balancing within SD-WAN rules requires an understanding of how the engine selects and distributes sessions across multiple links.
* SLA Target Logic (Option A): In FortiOS 7.6, theLowest Cost (SLA)strategy has been enhanced.
When the load-balance option is enabled for this strategy, the FortiGate does not just pick a single
"best" link; it identifiesall member interfaces that currently meet the configured SLA target(e.g., latency < 100ms). It then load balances the traffic across all those healthy links to maximize resource utilization.
* Hash Modes (Option D): When an SD-WAN rule is configured for load balancing (valid forManual andLowest Cost (SLA)strategies in 7.6), the administrator must define ahash modeto determine how sessions are distributed. While "outsessions" in the question is a common exam-variant typo for outbandwidth(or sessions-based hashing), the core principle remains: you can select the specific load- balancing algorithm (e.g., source-ip, round-robin, or bandwidth-based) forall strategieswhere load- balancing is enabled.
Why other options are incorrect:
* Option B and C: These options are too restrictive. InFortiOS 7.6, load balancing is not limited to only
"manual and best quality" or "manual and lowest cost" in a singular way. The documentation highlights thatManualandLowest Cost (SLA)are the primary strategies that support the explicit load-balance toggle to steer traffic through multiple healthy members simultaneously.
