QUESTION 2
A CallManager cluster topology of Cisco MCS 7835s (each capable of supporting
2500 calls) is being designed for an IP telephony network. The cluster design must
1) support up to 3,000 phones
2) provide a level of redundancy
3) be cost effective
4) support a very heavy streamed media file load.
Given those necessities, which of the following configurations requires the fewest number of CallManagers but still provides acceptable performance?

A. Four: Publisher, TFTP server, and two Primaries
B. Five: Publisher, TFTP server, two Primaries, and a Secondary (covering both
Primaries)
C. Four: combined Publisher and TFTP server, two Primaries, and a Secondary (covering both Primaries)
D. Six: Publisher, TFTP server, two Primaries, two secondaries (one for each Primary)
E. Six: Publisher, TFTP server, two Primaries, and a Secondary (covering both
Primaries), and a Tertiary (covering both Primaries)
F. Six: Publisher, TFTP server, two Primaries, two secondaries (one for each Primary), and two Tertiaries (one for each Primary)

Answer: B

QUESTION 3
What is required for a Cisco IP Phone to obtain an address from a Cisco
CallManager running the DHCP service if they are not both on the same subnet?

A. default router
B. option 150 with the IP address of the CallManager
C. option 86 with the IP address of the TFTP server

TK

D. IP helper address

Answer: D

Explanation: IP helper address modifies the IP phone DHCP broadcast to a unicast so the request can be routed to other subnets where DHCP server sits on.

QUESTION 4
Assume users are regularly moving throughout the enterprise. Which scenario is a good candidate for Extension Mobility?

A. multiple campuses, each as its own cluster
B. single campus, one cluster per building
C. multiple campuses, each connecting into a single cluster

QUESTION 5
What service must be activated on a Subscriber to support WebAttendant?

A. Cisco Database Layer Monitor
B. Cisco IP Voice Media Streaming
C. Cisco TFTP Server
D. Cisco CDR Insert
E. Cisco Telephony Call Dispatcher

Answer: E
Understanding the Cisco Telephony Call Dispatcher
The attendant console application registers with and receives call-dispatching services
from the Cisco Telephony Call Dispatcher (TCD). The Cisco TCD, a Cisco CallManager service, provides communication among Cisco CallManager servers, attendant consoles, and the Cisco IP Phones that are used with the attendant consoles.
Note
If you use the attendant console in a cluster environment, make sure that all CiscoCallManagers within a cluster have the CiscoTCD service activated and running. You must manually activate the service through CiscoCallManager Serviceability. Attendant console redundancy requires this setup to work properly; however, not all CiscoTCDs are required to have a route point.

QUESTION 6
A CallManager cluster topology of Cisco MCS 7835s (each capable of supporting
2500 calls) is being designed for an IP telephony network.

TK

The design must accomplish the following:
1. support up to 6,5000 phones
2. provide a minimal level of redundcy
3. be cost effective
Select the best configuration that requires the fewest number of CallManagers while still providing acceptable performance.

A. Three: Combined Publisher and TFTP server, and Two Primaries
B. Five: Publisher, TFTP server, and three Primaries
C. Seven: Publisher, TFTP server, three Primaries, and two Secondaries (each covering two Primaries)
D. Eight: Publisher, TFTP server, three Primaries, and three Secondaries (one for each
Primary)
E. Nine: Publisher, TFTP server, three Primaries, three Secondaries (each covering one
Primary), and one Tertiary

Answer: C
