642-071 Cisco Unity Design and Networking Practice Test

Demo Question 3.

EliteCertify.com maintains a distributed Legacy voice mail and messaging infrastructure. They also have a distributed call processing environment, consisting of Legacy PBX equipment. EliteCertify.com maintains a dual data center layout in San Diego, Californiaand Yuma, Arizonawith two smaller remote branch offices in Palm Springs and El Centro, California, connected to the data centers by 256k links. There are at least 500 users in both remote sites, with 2000 users in each data center. EliteCertify.com wants to move from their Legacy voice mail system to a Unified Messaging environment with Cisco Unity. You discuss options for collapsing the company's call processing infrastructure as well and find they cannot collapse their Legacy call processing environment to centralized Cisco CallManager. They must keep the Legacy PBXs functioning for at least two more years as stipulated by their lease agreement. You request all PBX type/release information from the customer and discover that their current PBXs are all supported by Cisco Unity. The PBX's are all from the same manufacturer, and 5 digit dialing is available from any phone in their network. Given that 5 digit dialing is available from any phone on the customer's network, which statement is true?

A. They do not need to enable more networking? on their PBXs
B. They can begin to collapse their call control environment to line up with the introduction of CallManager into their environment.
C. This means absolutely nothing to this design. Anytime you have remote offices that have mail stores across slow WAN links you MUST have a Unity server collocated with those stores.
D. They can centralize Unity in a single site. A single Unity can be installed in one of the data centers and can easily support 5000 total users. Since they have 5 digit dialing across their environment, the PBX's networking functions can take care of MWI's, etc.
