True or False: AD Sync will delete groups and users with no Central Admin role when they are no longer present in the search results?

AD Sync is a feature designed to synchronize Active Directory (AD) objects, such as users and groups, with an organization's Central Admin role. When a group or user with no Central Admin role is no longer found in the search results from the Active Directory, the synchronization process identifies that absence as a cue to remove those objects from the Central Admin system to maintain an accurate representation of the directory.

This removal helps ensure that the Central Admin reflects only current and active users and groups that should have access to the necessary resources, thus improving security and management efficiency. This automatic deletion is a built-in mechanism of AD Sync to reconcile differences between the AD source and the Central Admin, ensuring that outdated or irrelevant entries are not retained within the system.

The other options introduce conditions or scenarios that do not accurately represent how the AD Sync function operates. Therefore, the true and straightforward answer is that AD Sync will indeed delete groups and users without a Central Admin role when they are no longer present in the search results.
