Access Control Rule Restart

A.

When an engineer configures an access control rule that deploys file policy configurations to security zone or tunnel zones, and it causes the device to restart, there could be several reasons for this. However, based on the given options, we can eliminate a few of them to narrow down the possible reason.

Option A states that the source or destination security zones in the access control rule match the security zones that are associated with interfaces on the target devices. While this may cause an issue, it is not directly related to the device restarting, so we can eliminate this option.

Option B suggests that the source tunnel zone in the rule does not match a tunnel zone that is assigned to a tunnel rule in the destination policy. Again, while this may cause issues with traffic flow, it is unlikely to cause the device to restart, so we can eliminate this option as well.

Option C states that the source or destination security zones in the source tunnel zone do not match the security zones that are associated with interfaces on the target devices. This is a possibility since it could cause the device to become unstable or crash, but we cannot be certain without more information.

Option D suggests that the source tunnel zone in the rule does not match a tunnel zone that is assigned to a tunnel rule in the source policy. This is also a possibility since it could cause issues with traffic flow and potentially cause the device to restart.

Overall, based on the given options, the most likely reason for the device restart is either option C or D. However, without more information about the network topology, configuration, and logs, it is difficult to determine the exact cause of the issue. It is recommended to troubleshoot the issue further by reviewing the device logs and configuration, checking for any misconfigurations or errors, and verifying that the access control rules and tunnel policies are properly configured and aligned with the network topology.
