Fortinet Updated NSE6_FMG_AD-7.6 Exam Questions and Answers by carla

In a FortiManager HA cluster configured with VRRP failover, the failover process is automatic and transparent to administrators. If the monitored interface on the primary device fails, the secondary device takes over without requiring manual intervention to maintain HA.

The correct answer is D. The FortiManager 7.6 Administrator Study Guide states: “You can revert to a previous configuration revision” and “Reverts only the device database to the previous revision”. It also states “Does not revert policies and objects—you must import them” and “You must install reverted changes on FortiGate.”

This exactly means a revert operation changes the device-level database on FortiManager, not the policy layer database. The guide further clarifies: “Performing a revert operation followed by an installation only reverts device-level changes and does not revert policy packages.”

So C is incorrect because both layers are not reverted together. A and B are also incorrect because the documented and verified effect is specifically a modification of the device database, followed by install and, if needed, policy re-import for synchronization.

The FortiManager 7.6 Administrator Study Guide is explicit for the scenario where both FortiManager and FortiGate are behind NAT. It states that FortiManager can discover FortiGate through the FortiGate NATed IP address, which makes A correct. It also explains that in this scenario, the FortiManager NATed IP address is not configured on FortiGate by default under central management, which makes B correct.

C is incorrect because FortiGate must use the FortiManager NATed IP address, not the non-NATed IP, if it needs to announce itself or reestablish the FGFM tunnel. D is also incorrect because in this NAT scenario, if the tunnel is torn down, only FortiGate attempts to reestablish the connection; FortiManager does not automatically do so.

The most strongly supported answer is A. The study guide explicitly states: “In the case of having multiple FortiOS firmware versions on the same ADOM, it is recommended to use separate ADOMs instead.” It also says: “When you organize managed FortiGate devices, it is highly recommended that you group them based on their FortiOS firmware version. This is because valid command syntax varies by firmware version, which affects script compatibility.”

D is the other practical fix supported by FortiManager workflow. The study guide states that FortiManager can run scripts on multiple managed devices at once, and device groups let you run scripts on multiple devices instead of a single device. Combined with the firmware-version compatibility rule above, the correct operational approach is to keep version-specific scripts and apply them only to the matching device sets. B and C are not supported by the uploaded study guide as the recommended fix.
