Exhibit

CallManager Cluster A and Unity use extension range 1000-2500. CallManager Cluster B and unity use extension range 3000-3450. CallManager Cluster C and unity extension range 4200-
4400. Your customer Company.com wants to deploy Unified Messaging. Exchange stores are local at each site and part of the same organization. Digital networking is absolute requirement
without using access codes, and callers need to be able to use the Cisco Unity Auto Attendant to reach any user at any site. Which statement is true?

A. To deploy unified Messaging, You need three separate dialing domains.
B. Configure all Unity servers into the same dialing domain, and each Unity’s call handler search scope to that dialing domain.
C. Unity servers A and B are in the same dialing domain and the Unity C uses Extension masking
to address any extension conflicts with them.
D. No dialing domains need to be created. All unity servers need to know about each other via Active Directory. The CallManager cluster will handle any overlapping dial plan with partitions and calling search spaces.
Answer: B Question: 2
A customer has 22,000 users. Approximately 15,000 users are located at a centralized campus
area and the remaining 7,000 users are distributed across twenty separate remote locations.
All services are centralized, including telephony and messaging. Of the twenty remote locations, ten have a maximum of 50 users and a T1 WAN connection to the data center located at the
centralized campus. The customer wants Unified Messaging and wants to use text to speech.
They plan to roll out View Mail for Outlook (VMO) to all users, prior to installing Unity to service the centralized Exchange servers. How should VMO be configured for the remote users?

A. All remote users are configured to use unity inbox.
B. The remote VMO clients should be configured to use remote mode access.
C. The remote VMO clients should be configured to use Telephone Record and Playback (TRaP).
D. The remote VMO clients should be configured to only allow download before playback.

Telephone Record and Playback (TRaP) should not be used for the remote clients.
Answer: D Question: 3
Exhibit:

Which messaging deployment shown in the exhibit? A. branched messaging
B. distributed messaging
C. exchange clustered messaging
D. This is not a supported message deployment model.
Answer: D Question: 4
In a purely distributed environment for both call processing and messaging, you discover that you will need to have a single Unity server collocated in each branch. As you press for more
information regarding existing PBX’s and their layout, the customer the customer asks you why this PBX information is so important in a design. What is the best answer you can give the
customer?

A. You need to understand the PBX layout so you can design the Unity solution.
B. You do not need the PBX information as it is simply not important to this design.
C. You need more PBX information to determine how to effectively collapse? Their call
Processing environment for them.
D. You need the PBX information so you can determine which messaging system (Microsoft
Exchange or Lotus Domino) would best fit into their plans.
Answer: A Question: 5
If a customer has a distributed messaging deployment model, all messaging infrastructure
Components must also be distributed. If Unity will service Exchange 20C0, all the messaging infrastructure components that Exchange and Unity need should be collocated with them. For Exchange 2000 and unity, what messaging infrastructure components are necessary, and which are optional?

A. Both a domain controller and global catalog are necessary. Remote e-mail clients are not necessary. SQL servers are optional.
B. At least one Windows 2000 domain controller, one Windows 2000 global catalog server, and

That run at 256k. There are 500 subscribers in each physical site. There are five set and four of them mountain main stores. Cisco Unity design requirements state that a minimum you must
have how many Unity servers?

A. 2
B. 4
C. 5
D. 8
Answer: B Question: 7
Exhibit

CallManager Cluster A and unity use extension range 1000?650. CallManager Cluster B and
Unity use extension range 2000?450. CallManager Cluster C and Unity extension range
1500?950.Your customer Company.com wants to deploy Unified Messaging. Exchange stores are local at each site and part of the same organization. Digital networking is an absolute requirement without using access codes. Which statement is true?

A. All Unity servers are in different locations, but are part of the same dialing domain.
B. A unique dialing domain is created per unity location. The other Unity locations are automatically available at that time.
C. All Unity servers are in the same dialing domain and CallManager Cluster C to change the extensions that overlap with the CallManager Cluster A.
D. Unity servers A and B are in the same dialing domain and Unity C put into its own dialing
