Cybersecurity-Apprentice Network Security Practice Question
An administrator configures high availability (HA) active/passive mode between two identical firewall models. What happens to active sessions when a failover occurs if 'Session Synchronization' is enabled?
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
✓
Active sessions are synchronized to the passive peer, allowing seamless traffic continuity without dropping connections.
With HA session synchronization enabled, active stateful TCP and UDP sessions are synchronized to the peer firewall, preventing dropped connections during a failover.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Active sessions are synchronized to the passive peer, allowing seamless traffic continuity without dropping connections.
Why this is correct
Session sync ensures stateful session tables are replicated so traffic continues uninterrupted.
- ✗
All active user sessions are immediately terminated and must re-authenticate.
Why it's wrong here
Termination occurs if session synchronization is disabled.
- ✗
Management IP addresses are duplicated on both units simultaneously.
Why it's wrong here
Management IPs remain distinct while HA uses floating IPs for data interfaces.
- ✗
The passive firewall boots up from power-off state to take over.
Why it's wrong here
The passive unit is already running and synchronized in hot-standby.
