642-071 Cisco Unity Design and Networking Certification Exam

Demo Question 11.

EliteCertify.com maintains a wholly centralized electronic messaging environment in a single data center, physically located in Denver. The customer uses Microsoft Exchange exclusively, and at this time has a distributed, Cisco CallManager environment consisting of three separate clusters. These clusters support the Denverdata center plus three large remote sites in Colorado Springs, Boulderand Montrose. EliteCertify.com's plans call for moving from their centralized, 10 year old Legacy voice mail system to a Unified Messaging system. You offer Cisco Unity as a potential solution. Given the EliteCertify.com's topology for call processing and messaging, what is your recommendation?

A. You recommend centralized and distributed Unity servers. There are many choices available to you because of the inherent call processing flexibility built into a pure Cisco CallManager design. You recommend a hybrid solution to demonstrate to the customer the flexibility of the product.
B. You cannot provide an initial design at this time. The customer's need for three Cisco CallManager clusters has brought the design process to a standstill. You MUST go back and convince the customer to fully collapse the CallManager clusters for Cisco Unity to fit into their environment.
C. You recommend centralized Unity systems. Unity MUST reside as physically close as possible to the message stores it will be servicing. Also, since Cisco Unity servers are capable of servicing more than one Cisco CallManager cluster, you decide to offer a centralized messaging and distributed call processing design.
D. You recommend distributed Unity systems. Unity MUST reside as physically close as possible to the CallManager clusters, and Cisco Unity servers MUST maintain a one-to-one relationship to the number of CallManager clusters in the design. At a minimum, you must provide a three Cisco Unity solution, and they must be distributed to physically mirror the layout of the Cisco CallManager topology.
