Which utility should you use when you need to add a large number of users into Cisco Unified
Communications Manager?

A.
Cisco Unified User Administration

B.
Application User CAPF Profile

C.
Cisco Unified Communications Manager Bulk Administration Tool

D.
Cisco Unified Telephony User Administration

Explanation:
The Cisco Unified Communications Manager Bulk Administration Tool (BAT), a web-based
application, performs bulk transactions to the Cisco Unified Communications Manager database.
BAT lets you add, update, or delete a large number of similar phones, users, or ports at the same
time. When you use Cisco Unified Communications Manager Administration, each database
transaction requires an individual manual operation, while BAT automates the process and
achieves faster add, update, and delete operations.
