FORTINET-NSE123 Practice Question: Nse 2 Technical Introduction TO Fortinet Security

An enterprise is deploying FortiGate High Availability (HA) in active-active mode. How does active-active mode differ from active-passive mode regarding session handling?

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-active distributes session processing across multiple cluster units, whereas active-passive processes all traffic on a single primary unit

In active-active mode, session load is distributed across multiple cluster members using session-pickup/load-balancing mechanisms, whereas active-passive runs all traffic through the primary unit until a failover occurs.

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-active requires manual administrator failover, while active-passive is fully automated

    Why it's wrong here

    Both HA modes provide automated failover via the FGCP protocol.

  • Active-active disables all firewall security profiles to maximize raw throughput

    Why it's wrong here

    Security profiles function identically across active-active and active-passive HA clusters.

  • Active-active distributes session processing across multiple cluster units, whereas active-passive processes all traffic on a single primary unit

    Why this is correct

    Active-active mode shares session processing across multiple active cluster members.

  • Active-active eliminates the need for heartbeat cables between cluster units

    Why it's wrong here

    Heartbeat connections are mandatory in all FGCP clustering modes.
