Question 20
A regional SOC analyst is asked to resolve this problem: An active-passive FortiGate pair fails over and logs begin arriving under a different member serial, causing a saved device-specific search to appear empty. What preventive practice should be standardized for this FortiAnalyzer workflow?
Explanation
Correct Answer
This safeguard directly addresses logging health with clustered fortigate devices: Validate HA-aware device groups and log selectors in SOC content during planned firewall failovers. The risk being prevented is: HA failover changes the active origin of device logs, so filtering by only the former active member can hide valid post-failover activity. A safeguard aimed at another fault would not control this issue.
Incorrect Answers
A completed backup job is not proof that the required stored log files are intact and recoverable for investigation. “Maintain periodic recovery drills and validate retention and access controls on backup copies” would remedy that alternative situation, but it would not correct the present issue: HA failover changes the active origin of device logs, so filtering by only the former active member can hide valid post-failover activity.
“Track delivery lag and preserve both timestamp interpretations in outage investigations” is the supported response when delayed delivery collapses receipt timestamps even when the original event timestamps are spread over an earlier interval. Here the decisive response is “Validate HA-aware device groups and log selectors in SOC content during planned firewall failovers”, so that different intervention does not meet the stated requirement.
Successful login does not automatically confer authorized log-view rights or an assignment to the affected administrative domain. “Test representative read-only analyst profiles after administrator and ADOM permissions are changed” applies to that other condition. The reported evidence is an active-passive FortiGate pair fails over and logs begin arriving under a different member serial, causing a saved device-specific search to appear empty; this alternative would address the wrong dependency.
