voice­mail system of your supplier supports only blind addressing, they want to use the full DID number to send messages to you. Which prefix should be configured in Cisco Unity server VPIM delivery location?

B. clustered messaging
C. centralized messaging D. distributed messaging Answer: C

19. A customer maintains a wholly centralized Exchange messaging environment in a single data center located inDenver. The customer has a distributed Cisco Unified CallManager environment consisting of three separate clusters. These clusters support the Denver data center plus three large remote sites in Colorado Springs, Boulder,
and Montrose. The customer plans to move from their centralized 10­year­old legacy voice­mail system to
a CiscoUnity Unified Messaging system. Given the customer topology for call processing and messaging, what is your recommendation?
A. You recommend centralized and distributed Cisco Unity servers. There are many choices available to you because of the inherent call processing flexibility built in to a pureCisco Unified 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 need for three Cisco Unified
CallManager clusters has brought the design process to a standstill. Tell the customer to fully collapse the
Cisco Unified CallManager clusters for Cisco Unity to fit into their environment.
C. You recommend centralized Cisco Unity systems. Cisco Unity must reside as close as physically possible to the message stores it will be servicing. Also, since Cisco Unity servers are capable of servicing more than one Cisco Unified CallManager cluster, you offer a centralized messaging and distributed call­processing design.
D. You recommend distributed Cisco Unity systems. Cisco Unity must reside as close as physically possible to the Cisco Unified CallManager clusters, and Cisco Unity servers must maintain a one­to­one relationship to the number of Cisco Unified CallManager clusters inthe design. At a minimum you must provide a three Cisco Unity solution and the three solutions must be distributed tophysically mirror the layout of the Cisco Unified CallManager topology.
Answer: C

20. Refer to the exhibit. Which type of Cisco Unity deployment model is shown?

A. The exhibit does not show a valid model combination.
B. centralized call processing, distributed messaging
C. distributed call processing, distributed messaging
D. localized call processing, localized branch messaging
Answer: A

21. Refer to the exhibit. Which messaging deployment model is shown?

A. branched messaging
B. distributed messaging
C. clustered Exchange messaging
D. This is not a supported message deployment model. Answer: D

22. You are designing a Cisco Unity voice­mail­only solution to allow all outside callers at any of the 14 different company offices to locate any of the 7500 users by simply spelling the name of the user via the touch­tone telephone keypad in an Automated Attendant conversation. Each office has a different
voice­mail system that you will replace with the new Cisco Unity solution. Each office also has a separate telephone system. The telephonesystems come from various manufacturers. Users dial individual 10­digit phone numbers to reach each user. There is no telephone networking between offices. Many of the telephone systems will not allow conferencing and have a limited number of trunks for each office. The customer is not willing to change the telephone system structure at this time. Which solution best meets

the customer needs?
A. This can be done with VPIM, which is an industry standard that allows different telephone systems to integrateover the Internet.
B. This can be done with the optional Cisco Unity PBX conference feature that allows transfers between different PBXs by using the Intel Dialogic voice cards installed in all Cisco Unity servers.
C. You can network the Cisco Unity systems together for subscriber­to­subscriber messaging, but to fulfill the requirements they want for Automated Attendant transfers between offices, they need to change to a networkedtelephone system solution.
D. Create a new forest/domain and add one Cisco Unity server at each office. All Cisco Unity systems are memberservers in the forest/domain and are provisioned for the number of users at that site. On one
Cisco Unity server adialing domain is created and all other Cisco Unity servers join that dialing domain. The directory handler searchscope is set to that dialing domain.
Answer: C

23. Your customer has 1200 users. The users are spread evenly across three routing groups in one Exchange 2000organization. Each routing group is in a different geographical location within a single phone system. You need toconfigure a voice­mail­only solution with a plan to migrate to unified
messaging. They must have the ability tosend an all­employee message to one distribution list and have the Automated Attendant search for all users byname regardless of the location. Which configuration
meets the customer requirements?
A. a new forest/domain with one Cisco Unity system in each new Exchange routing group
B. a new forest/domain with three Cisco Unity systems in each new Exchange routing group
C. a new forest/domain with one Cisco Unity system in the existing root Exchange routing groups
D. There is no Cisco Unity solution that fits this Exchange 2000 configuration. Answer: A

24. Your customer has a requirement of a voice­mail­only system with redundancy/failover to service their
10,000 users in locations across Europe. They plan to create a new forest/domain for the Cisco Unity installation withExchange servers for off­box message storage. They plan to install one Cisco Unity server with failover inFrankfurt, Berlin, and London. Telephone traffic at the London location at times exceeds the current Cisco Unity port capacity. They plan to use the failover server in London for overflow capacity.
What do you tell the customer? A. This will work as planned.
B. They need to purchase the license pooling feature.
C. They need to install a second Cisco Unity server set in London. D. This will work if the SQL port synchronization feature is enabled.
Answer: C

25. Your customer developed a preliminary Bill of Materials for a Cisco Unity voice­mail­only installation
for their two locations. They will create a new forest/domain (VM.com) and use off­box Exchange
message stores. Their Bill of Materials shows two Exchange servers and two Cisco Unity servers. They plan on using the domaincontrollers/global catalog servers in their existing domain for authentication. What do you tell the customer?

A. Cross­box authentication must be enabled on the Cisco Unity server.
B. The Bill of Materials is accurate.
C. A domain controller/global catalog is needed in VM.com
D. The customer should use on­box Exchange message store. Answer: C

26. Refer to the exhibit. The exhibit shows a voice­mail­only installation plan. Does this plan meet Cisco

Unitybest practices?

A. Yes.
B. No. You must add Cisco Unity and associated resources for the Boston location.
C. No. The Manhattan site requires another Cisco Unity server for the second Exchange server.
D. No. A DC/GC is required in Manhattan. Answer: D

27. You are developing a plan for a Cisco Unity Unified Messaging installation for a customer. The
customer messaging infrastructure consists of three Exchange administrative groups. The total number of Cisco Unity users will not exceed 5000.Based on only the information provided, how many Cisco Unity servers will you propose?
A. 1
B. 2
