Exam NSE5_FNC_AD_7.6 Topic 1 Question 12 Discussion

The correct answer is D . The log output shows the local IP address as 192.168.10.10 , which the question identifies as the primary FortiNAC-F server. In the same output, FortiNAC-F reports inControl true and controlServer true , which means the local primary server is currently the control server. The line showing communication to 192.168.10.110 returns Running - Not In Control , confirming that the secondary server is alive but is not the active controlling node.
This matches FortiNAC-F 1+1 HA behavior. The study guide describes a 1+1 HA pair as an active-passive deployment where one FortiNAC-F device is designated primary and the other secondary. Database and configuration synchronization keep the devices aligned, but only one server is in control at a time. If the primary fails, the secondary assumes control automatically; otherwise, the primary remains the active control server.
Option A is wrong because the secondary explicitly reports Not In Control . Option B is wrong because the output does not show database replication failure. Option C is wrong because failover is not in progress; the output shows a stable state where the primary is in control and the secondary is running as the passive node.
