QUESTION 34
Your customer Certkiller .com requests that you configure a large voice mail only
application with the ability to handle 80 calls simultaneously. These capabilities
must always be available. You must determine the number of servers necessary to
provide the call handling capacity.
Which configuration best meets the customer’s requirements?
A. one 80-port Unity server and one 80-port fallover server
B. two servers: one 40-port fallover server and one primary 40-port Unity server
C. three servers: two 40-port Unity primary servers and one server to act as the fallover
server for both primary servers.
D. four servers: two 40-port Unity primary servers and two 40-port fallover Unity
servers.
Answer: D
QUESTION 35:
Your customer Certkiller .com asks you to plan a large Unified Messaging Cisco
Unity solution for their 22,000 users. They are currently upgrading all of the sites
into one forest with Exchange 2003 as the standard for all e-mail servers. They will
complete the upgrade in three years, so they want a temporary voice mail only
solution with a clean migration path.
Following best practices, how can you accomplish this?
A. create a separate forest/domain with new servers provisioned for the 22,000 users and
use the same Exchange alias naming convention
B. create a separate forest/domain with new servers provisioned for the 22,000 users and
use a separate Exchange alias naming convention so there are no overlapping GUID
issues
C. join the forest/domain; add new servers provisioned for the 22,000 users; use the same
Exchange alias naming convention so users can be changed as they are upgraded
D. join the forest/domain: add new Unity servers provisioned for the 22,000 users; use
the existing mail store and user alias; control which users get Unified Messaging via the
COS of the users as they are upgraded
Answer: A
QUESTION 36
Your customer Certkiller .com requires you to plan a voice mail only solution for
6,000 users. All users are at one physical location and they all use one phone system.
Due to the volume of calls this customers receives, you propose two Cisco Unity
72-port systems, each configured to service half of the users. When a message is left
for a specific distribution list, the customer requires that 50 people be
simultaneously notified via touch tone paper or cell phone call. The normal call
volume generally keeps half of the ports on both systems busy.
Without accounting for MWIs, which solution best meets the customer’s
requirements?
A. configure 25 ports on both systems for out call notification and locate half of the users
on each system
B. configure 50 ports on one system for out call notification and locate the users in that
distribution list on that server
C. configure 50 ports on one system for out call notification and locate the users in that
distribution list on the other server
D. This requirement cannot be met. Members in distribution lists must be located on the
same Cisco Unity server to function properly.
