* Option B: To save the current state of all policy packages and objects for an ADOMis the correct answer. ADOM (Administrative Domain) revisions in FortiManager are used to create a snapshot of the current state of all policy packages and objects associated with an ADOM. This allows administrators to save a specific configuration state and revert to it if necessary. It helps in managing changes and recovering from configuration errors or unintended changes.
* Explanation of Incorrect Options:
* Option A: To save the current state of the whole ADOMis incorrect because ADOM revisions specifically save only the policy packages and object configurations, not the entire state of the ADOM, which may include logs, reports, and other non-policy data.
* Option C: To revert individual policy packages and device-level settings for a managed FortiGateis incorrect as ADOM revisions are not meant for reverting individual policy packages or device settings; they are designed to handle the entire set of policy packages and objects within an ADOM.
* Option D: To save the FortiManager configuration in the System Checkpointsis incorrect because ADOM revisions do not function as system checkpoints for FortiManager itself; they are specific to ADOM policy packages and objects.

* Refer to the FortiManager 7.4 Administration Guide, "ADOM Management" section, which describes the purpose and usage of ADOM revisions for configuration management and restoration.
