Which statement about the communication between FortiGate high availability (HA) clusters and FortiAnalyzer is true?

If devices were registered to FortiAnalyzer before forming a cluster, you can manually add them together.

FortiAnalyzer distinguishes each cluster member by the IP addresses in log message headers.

If the HA primary device becomes unavailable, you must remove it from the HA cluster list on FortiAnalyzer.

The FortiGate HA cluster must be in active-passive mode in order to avoid conflict.
