The correct answer is C. Wait until 3:15 a.m. on March 6th for garbage collection to remove the user from Cisco UCM. When an LDAP synchronized user is deleted from Active Directory, Cisco UCM marks the user as inactive during the next sync, with permanent removal occurring during a subsequent garbage collection process that runs after 24 hours of inactivity.

Why each option

When an LDAP synchronized user is deleted from Active Directory, Cisco UCM marks the user as inactive during the next sync, with permanent removal occurring during a subsequent garbage collection process that runs after 24 hours of inactivity.

AWait until 10 pm on March 4th when the user is automatically removed from Cisco UCM

While the user is marked inactive at 10 pm on March 4th, they are not immediately *removed* from the CUCM database at that time; removal is a separate garbage collection process.

BWait until 10 pm on March 5th when the user is automatically removed from Cisco UCM.

Waiting until 10 pm on March 5th only covers another sync cycle; the actual permanent removal happens via garbage collection, which has a 24-hour delay.

CWait until 3:15 a.m. on March 6th for garbage collection to remove the user from Cisco UCM.Correct

When an LDAP synchronized user is deleted from Active Directory, the nightly sync (March 4th at 10 p.m.) marks the user as inactive in Cisco UCM. The user is then permanently removed by the Cisco UCM garbage collection process, which typically runs in the early morning hours (e.g., 3:15 a.m.) on the second day *after* the user is marked inactive, meaning on March 6th.

DWait until 3:15 a.m. on March 5th for garbage collection to remove the user from Cisco UCM

3:15 a.m. on March 5th is too early for garbage collection to remove a user whose inactive status was registered on March 4th at 10 p.m., as garbage collection acts on users marked inactive for at least 24 hours.
