FORTINET-NSE123 Practice Question: Nse 2 Technical Introduction TO Fortinet Security
An organization requires high availability (HA) for two FortiGate devices to ensure continuous network uptime during hardware failures. Which operating mode synchronizes sessions, configuration, and routing state between the primary and secondary units in an active-passive cluster?
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
✓
FortiGate Clustering Protocol (FGCP) Active-Passive mode
FGCP (FortiGate Clustering Protocol) in an active-passive high availability configuration synchronizes session tables and configurations so the secondary unit can seamlessly take over if the primary fails.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Dynamic Multicast Routing Protocol (PIM-SM)
Why it's wrong here
PIM is used for multicast traffic routing, not firewall high availability clustering.
- ✓
FortiGate Clustering Protocol (FGCP) Active-Passive mode
Why this is correct
FGCP active-passive synchronization ensures session failover and seamless high availability.
- ✗
Virtual Router Redundancy Protocol (VRRP) active-active balancing
Why it's wrong here
VRRP is a standard L3 gateway redundancy protocol, whereas FGCP is Fortinet's native clustering solution.
- ✗
Border Gateway Protocol (BGP) Multipath clustering
Why it's wrong here
BGP is an exterior routing protocol for internet path selection, not device-level clustering.
