NSE7 Advanced Networking and SD-WAN Practice Question
A FortiGate is configured with ECMP routing to balance traffic across two default routes via two ISPs. The administrator wants to ensure that traffic from the same source-destination pair always uses the same ISP. Which ECMP load balancing method should be configured?
⚠ Common exam trap
It's easy for candidates to confuse 'session' as a valid ECMP method, but FortiGate does not have a 'session' load balancing option; the correct flow-based method is 'source-dest-ip'.

Correct answer & explanation
✓
source-dest-ip
The source-dest-ip method hashes the source and destination IP addresses to compute a consistent path for all packets in a given flow. This ensures that traffic from the same source-destination pair always uses the same ISP, meeting the requirement for flow-based persistence without per-packet load balancing.
