Braindumps for "642-071" Exam

Cisco Unity Design and Networking

 Question 1.
Is it possible for Unity to connect to the same global catalog server as the Exchange 2000 server it is servicing, if Unity is installed in its own Windows 2000 site?

A. No, it is not possible because a global catalog server can only service one Windows 2000 site.
B. No, it is not possible because the Exchange 2000 servers replicate too much directory 
    information.
C. Yes it is possible as long as you edit the registry and point Unity to the correct global catalog 
     server.
D. Yes it is possible because a global catalog server can be configured to support up to five 
    Windows 2000 sites.

Answer: A

Question 2.
Exhibit:

 

Which Cisco Unity type of deployment model is shown in the exhibit?

A. centralized call processing, distributed messaging
B. centralized call processing, centralized messaging
C. distributed call processing, decentralized messaging
D. localized call processing, localized branch messaging

Answer: A

Question 3.
ITCertKeys.com maintains a distributed Legacy voice mail and messaging infrastructure. They also have a distributed call processing environment, consisting of Legacy PBX equipment.

ITCertKeys.com maintains a dual data center layout in San Diego, California and Yuma, Arizona with 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. 

ITCertKeys.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 Call Manager. 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 Call 
     Manager 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.

Answer: C

Question 4.
Exhibit:

 

Why is the Cisco Unity deployment shown in the exhibit NOT supported?

A. Digital networking will not work over the WAN.
B. There are two Cisco Unity servers installed at headquarters.
C. A Cisco Call Manager cluster is required at the branch office.
D. The Cisco Unity branch office server is remote from a message store.

Answer: D

Question 5.
Exhibit: #1

 

Exhibit: #2

 

In Exhibit: 1, the Call Manager cluster and Unity use the extension range 3000? 4200. 

Your customer ITCertKeys.com wants to deploy Unified Messaging. Exchange stores are local at the data center and are part of the same organization. Digital networking is an absolute requirement without using access codes. Exhibit: 2 Shows how the IT organization expects to accommodate future growth.

What is the best solution with regard to dialing domains?

A. A completely unique "dialing location" is created in Call Manager and Unity is assigned to that 
     location.
B. All Unity servers need to be in the same dialing domain. This poses no problem given its 
     simple environment.
C. A unique dialing domain is created at each Unity location. The other Unity locations are 
     automatically available at that time.
D. Future growth is planned for by allowing all Unity servers to be in different locations and to be 
     part of separate dialing domains.

Answer: B

Question 6.
Your customer ITCertKeys.com has fully distributed message store environment across WAN links 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:

 

Call Manager Cluster A and unity use extension range 1000?650. Call Manager Cluster B and Unity use extension range 2000?450. Call Manager Cluster C and Unity extension range 1500? 950.

Your customer ITCertKeys.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 Call Manager Cluster C to change the 
     extensions that overlap with the Call Manager Cluster A.
D. Unity servers A and B are in the same dialing domain and Unity C put into its own dialing 
    domain to address the extension conflicts with Unity A and B.

Answer: C

Question 8.
Exhibit:

 

Each remote location has 15 users with a telephone and voice mailbox, with a 256K WAN link. Trans coding is available at the main location.

Which codec(s) can Unity default configuration support?

A. G.726 only
B. G.711 only
C. G.729a only
D. G.711 and G.726
E. G.711 and G.729a

Answer: E

Question 9.
Your customer ITCertKeys.com has five Lotus Domino domains and manages five separate address books, along with five remote mail stores. They do this as result of recent acquisitions. They would like to merge these in the future and want to understand how this affects their Cisco Unity considerations today.

Which statement is true?

A. They need to consolidate address books before they can install Unity
B. They need least three Unity servers. Each Unity can connect to two names .nfs servers 
     simultaneously.
C. They need at least one Unity server in this environment, as Unity can service an unlimited 
     number of address books.
D. They need at least five Unity servers. A single Cisco Unity can only monitor one copy of 
     names. nfs at a time, from a single Domino domain.

Answer: D

Question 10.
Exhibit:

 

Which Cisco Unity messaging model is shown in the exhibit?

A. branched messaging
B. clustered messaging
C. centralized messaging
D. distributed messaging

Answer: C

Question 11.
A customer maintains a distributed Legacy voice mail and messaging infrastructure. They also have a distributed call processing environment, consisting of Legacy PBX gear they maintain a dual data center layout in Los Angeles and Bakersfield, with two smaller remote branch offices in San Diego and El Centro.

One of their goals this fiscal year is to collapse their messaging environment into a centralized topology, and gain increased return on investment by streamlining processes and administration through their two data centers. They want to move from their Legacy voice mail system to a Unified Messaging environment with Cisco Unity.

You request a meeting with the customer to discuss options for collapsing their call processing infrastructure as well. At this meeting, you find they cannot collapse their

Legacy call processing environment to centralized Cisco Call Manager. They must keep the Legacy PBX's Functioning for at least two more years as stipulated in their lease agreement.

Centralizing messaging is their first priority. You request all PBX type/release information from the customer and you discover that their current PBX's are fully supported by Cisco Unity. The PBX's are all from the same manufacturer, capable of networking functions and can take care of MWI's. 5-digit dialing is available from any phone in their network. 

What is your recommendation to the customer?

A. You recommend centralized Unity servers. Unity MUST reside as close as possible to the 
     centralized mail stores it will be servicing. You can easily centralize the unity connection to the 
     local PBX's, while servicing the remote branch office users at the same time.
B. You recommend centralized AND distributed Unity servers. You can centralize at the data 
     centers and distribute to the edge. You MUST do this to meet the customers requirements for 
     transparent dialing throughout the entire organization, and to comply with the 5 digit dial plan 
     they have in place today.
C. You recommend distributed Unity servers. Unity MUST reside as close as possible to the 
     centralized mail stores. HOWEVER in case of 5 digit dialing, you MUST physically place the 
     Unity servers as close as possible to the remote branch users to be functional. This 
     requirement overrides the need to be close to the mail stores, and you must consider in your 
     design.
D. You recommend centralized Unity servers. Unity MUST reside as close as possible to the 
      centralized mail stores it will be servicing. You can easily centralize the Unity connection to    
     the PBX's, while servicing the remote branch office users at the same time. The only caveat 
     you must discuss with the customer is the issue with the dual-switch? Capability that Unity 
     must leverage to simultaneously connect to Call Manager and the Legacy PBX's in the remote 
     sites.
