What will happen to users added alter the upgrade if you roll back to the inactive partition?

You have recently upgraded to a Cisco Unified CallManager 5.0 cluster. What will happen to users
added alter the upgrade if you roll back to the inactive partition?

A.
The user database for the active partition will need to be synchronized with the inactive partition
after the inactive partition becomes active to add the new users.

B.
The active partition maintains a backup copy of the user database that is used when the
inactive partition is activated.

C.
User information will be lost and those users added after the upgrade will need to be reentered.

D.
The two partitions share a common database. When the inactive partition becomes active,
users will already be populated.

Explanation:
Upgrading Cisco Unified CallManager Release 5.0(1)
You can only make changes to the database on the active partition. The database on the inactive
partition does not get updated. If you make changes to the database after an upgrade, you must

repeat those changes after switching the partition.
