Question 480
A maintenance team replaces the secondary FortiGate with a unit on a different firmware build and assumes its policies will synchronize without checking compatibility. Which diagnostic evidence should the FortiGate administrator check FIRST?
Explanation
Correct Answer
Inspect HA group name and password, heartbeat link status, cluster member health, firmware/build compatibility, priority settings and synchronization checksums. This distinguishes the relevant FortiGate device, session or controller evidence. FGCP heartbeat must operate over suitable dedicated links; two matching hostnames alone cannot build a synchronized HA pair or guarantee traffic survival. The corresponding action is: Configure compatible FortiGate peers as an FGCP high-availability cluster with appropriate heartbeat interfaces, group identity, matching licenses and tracked interfaces. Scenario: A maintenance team replaces the secondary FortiGate with a unit on a different firmware build and assumes its policies will synchronize without checking compatibility.
Incorrect Answers
Inspect FortiAnalyzer registration and authorization, connectivity, device identity, log forwarding state, log types, policy logging settings and timestamps. This diagnostic is related to FortiAnalyzer registration and centralized log forwarding rather than the controlling evidence for this scenario. Examine instead: Inspect HA group name and password, heartbeat link status, cluster member health, firmware/build compatibility, priority settings and synchronization checksums. Scenario: A maintenance team replaces the secondary FortiGate with a unit on a different firmware build and assumes its policies will synchronize without checking compatibility.
Inspect reserved management configuration, independent management routes, peer access, HA firmware upgrade status, pre/post checksums and cluster election events. This diagnostic is related to Reserved HA management, monitoring and firmware upgrades rather than the controlling evidence for this scenario. Examine instead: Inspect HA group name and password, heartbeat link status, cluster member health, firmware/build compatibility, priority settings and synchronization checksums. Scenario: A maintenance team replaces the secondary FortiGate with a unit on a different firmware build and assumes its policies will synchronize without checking compatibility.
Inspect user group mapping, SSO state, endpoint registration, FortiClient agent status, posture checks, FortiSASE portal permissions and applied access policy. This diagnostic is related to FortiSASE endpoint onboarding and identity-bound access rather than the controlling evidence for this scenario. Examine instead: Inspect HA group name and password, heartbeat link status, cluster member health, firmware/build compatibility, priority settings and synchronization checksums. Scenario: A maintenance team replaces the secondary FortiGate with a unit on a different firmware build and assumes its policies will synchronize without checking compatibility.
