A customer is seeking proposals to replace their voice-mail system with a Unified Messaging system, which is to be coordinated with their Exchange 2003 rollout. They have 2000 employees at their headquarters location, 800 employees at their data center, and 1000 employees at their 80 branch locations. Headquarters has redundant OC-3 connections to the data center and is using a Nortel PBX. They have recently deployed a Cisco Unified CallManager cluster at the data center, which provides centralized call processing for the branch locations. The Unified Messaging system must provide call answering and MWI for the IP phones and the existing Nortel PBX. The customer has a corporate
policy that all server resources must be located at the data center when possible. Your preliminary design calls for a Cisco Unity server at the data center that will integrate with the new Exchange 2003 servers to provide unified messaging for all employees.
Which two should be included in your preliminary design to make this a Cisco-supported design? (Choose two.)
A.
Cisco Unity server at headquarters
B.
Active Directory forest dedicated for Cisco Unity
C.
Partner Exchange server at headquarters
D.
Active Directory server dedicated for Cisco Unity
E.
Global Catalog server dedicated for Cisco Unity
