An administrator created a new global policy package that includes header and footer policies and...

Option A: To assign another global policy package later to the same ADOM, you must unassign this policy first.This is correct. FortiManager does not allow multiple global policy packages to be assigned to a single ADOM simultaneously. If you want to assign a different global policy package, the existing one must be unassigned first.

Option C: You can edit or delete all the global objects in the global ADOM.This is correct. Once a global policy package is assigned, you have the flexibility to edit or delete global objects in the global ADOM, affecting all ADOMs to which this package is assigned.

Explanation of Incorrect Options:

Option B: After you assign the global policy package to an ADOM, the impacted policy packages become hidden in that ADOMis incorrect because the policy packages do not become hidden; they are modified according to the global policies.

Option D: You must manually move the header and footer policies after the policy assignmentis incorrect because header and footer policies are automatically applied when assigned.
