NSE7 Troubleshooting and Diagnostics Practice Question
In an HA cluster, after a failover, some established sessions are not being synchronized to the new primary unit. Which setting must be enabled to ensure session synchronization?
⚠ Common exam trap
Many exam-takers confuse 'session-pickup' with general HA synchronization or misremember the exact CLI command, often selecting 'set sync-sessions enable' which sounds plausible but does not exist in FortiGate's configuration.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
set session-pickup enable
Session-pickup is the FortiGate HA feature that synchronizes the state of established sessions from the primary unit to the backup unit. When a failover occurs, the new primary unit can continue forwarding traffic for those sessions without interruption only if session-pickup is enabled. Without it, all existing sessions are dropped and must be re-established by the clients.
