Question 690
An engineer upgrades one HA member directly to an unsupported image and leaves the cluster split between incompatible FortiOS versions. Which observable result BEST demonstrates that the intended FortiGate security or connectivity requirement is satisfied?
Explanation
Correct Answer
Operators can reach and diagnose both nodes even when traffic fails over, and upgrades maintain a recoverable and healthy cluster state. This is the operational validation outcome rather than merely an enabled setting. Access to the virtual cluster primary is not the same as independent access to each physical peer, and an HA firmware upgrade requires build compatibility and sequence planning. Scenario: An engineer upgrades one HA member directly to an unsupported image and leaves the cluster split between incompatible FortiOS versions.
Incorrect Answers
Supported established sessions survive or reconnect within documented expectations after a primary failure, with no uncontrolled security policy bypass. This result would test HA session-pickup and failover continuity but does not demonstrate the desired FortiGate outcome here. Verify instead: Operators can reach and diagnose both nodes even when traffic fails over, and upgrades maintain a recoverable and healthy cluster state. Scenario: An engineer upgrades one HA member directly to an unsupported image and leaves the cluster split between incompatible FortiOS versions.
The FortiGate instance is licensed and reachable through approved cloud paths while cloud IAM and network controls retain least privilege. This result would test Cloud FortiGate licensing and infrastructure ownership boundaries but does not demonstrate the desired FortiGate outcome here. Verify instead: Operators can reach and diagnose both nodes even when traffic fails over, and upgrades maintain a recoverable and healthy cluster state. Scenario: An engineer upgrades one HA member directly to an unsupported image and leaves the cluster split between incompatible FortiOS versions.
Only appropriately enrolled and authenticated endpoints reach approved applications, with denied or noncompliant clients producing interpretable policy evidence. This result would test FortiSASE endpoint onboarding and identity-bound access but does not demonstrate the desired FortiGate outcome here. Verify instead: Operators can reach and diagnose both nodes even when traffic fails over, and upgrades maintain a recoverable and healthy cluster state. Scenario: An engineer upgrades one HA member directly to an unsupported image and leaves the cluster split between incompatible FortiOS versions.
