NSE6_FMG_AD-7.6 Exam Dumps - Fortinet NSE 6 Network Security Specialist Questions and Answers

Limiting ADOM revisions reduces the number of stored historical configurations, which helps avoid performance degradation and slow ADOM upgrades caused by a large volume of revisions.

Enabling workflow mode along with the ADOM lock feature ensures that all configuration changes go through a centralized review and approval process before installation, allowing controlled and coordinated management of firewall policies by multiple administrators.

Running a script on the Device Database marks the configuration as modified but does not immediately apply changes to the device.

The administrator must use the Install Wizard to push and install these changes from the Device Database onto the managed device.

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.

=========

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 exhibit shows Remote-FortiGate with a green closed lock icon, which indicates a locked policy package. The FortiManager 7.6 Administrator Study Guide states: “Policy locking is available in workspace normal and per-ADOM modes” and “Policy locking allows administrators to work on and lock a single policy package instead of locking the whole ADOM.” This confirms that a package such as Local-FortiGate_root can also be locked, so A is correct.

B is incorrect because the study guide and lab guide describe snapshots as ADOM revisions, not policy package snapshots: “An ADOM revision creates a snapshot of the policy and object configuration for the ADOM.”

D is incorrect because in workflow mode, sessions and approval are required before installation. The exhibit shows a normal save/lock state, not a workflow session state.

=========

In backup mode, FortiManager does not directly manage policy installation via the usual ADOM policy packages; instead, administrators use FortiManager scripts to push configuration changes, including policies, to FortiGate devices.

The correct answer is B. The FortiManager 7.6 Administrator Study Guide gives the exact extract: “Performing a revert operation followed by an installation only reverts device-level changes and does not revert policy packages. To achieve full synchronization, you must run the Import Configuration tool on FortiManager to synchronize the policy package.”

The guide also states: “After every retrieve, auto-update, or revert operation, you must use Import Configuration to ensure the policy information is synchronized.”

In the exhibit, the missing unset comment for policy ID 1 is a policy package issue, not just a device-level revert issue. Reinstalling the existing policy package does not automatically rebuild it from the reverted revision. The administrator must import the firewall policies again so the policy package reflects the reverted policy state. That is why the comment was not removed.

=========

The FortiManager 7.6 Administrator Study Guide states that global policies must be explicitly assigned: “You must explicitly assign global policy packages to specific ADOMs,” and FortiManager can also target specific policy packages in individual ADOMs. The lab guide confirms that assignment is performed from the Global Database ADOM: the administrator selects Global Database ADOM, clicks Assignment, adds the ADOM, chooses Specify Policy Packages To Assign, selects the target package, and then clicks Assign.

So creating a new policy package inside ADOM1 does not automatically inherit the existing global package assignment. It also does not automatically install policies. The administrator must go back to the global ADOM and assign the global policy package to that new local policy package.
