Explanation:
Why Choose H.323
* Integrated access
* Caller ID support on analog FXO
* Many more TDM interface types and signaling
* Dropping DSPs on hairpinned calls
* Gateway-resident applications like TCL and VXML
* CAC network design with H.323 gatekeepers
* No release dependencies between gateways and Cisco CallManager
* Much easier migration architecture to SIP
* Call preservation for Cisco SRST
* NFAS support
Implementing Cisco Voice Gateways and Gatekeepers (GWGK) v1.0
pg 1-66 Function of Gateways and Gatekeepers
Using MGCP as the call control protocol to a gateway has the following advantages:
* Centralized configuration, control and download from Cisco CallManager
* Better feature interaction with capabilities like caller ID and name display
* Easy, centralized dial-plan management
* Gateway voice security features (voice encryption) as of Cisco IOS Software Release
12.3.(5th)T
* Q Signaling (QSIG) supplementary services as supported by Cisco CallManager:
- Cisco CallManager interconnects to a QSIG network using an MGCP gateway and T1
or E1 PRI connections to a private integrated services network (PISN). The MGCP gateway establishes the call connections. Using the PRI backhaul mechanism, the gateway passes the QSIG messages to the Cisco CallManager to set up QSIG calls and send QSIG messages to control features.
- When a PBX is connected to a gateway that is using QSIG via H.323, calls that are
made between phones on the PBX and IP phones attached to the Cisco CallManager can have only basic PRI functionality. The gateway that terminates the QSIG protocol
provides only the calling line ID (CLID) and DID number, instead of Cisco CallManager providing that information.
* Enhanced call survivability:
- Calls from IP phones through an MGCP gateway are preserved on a CallManager

failover. This feature avoids dropped calls when applying the monthly operation system
service release on the Cisco CallManagers
- In SRST mode, calls from IP phones through an MGCP gateway are preserved on
MGCP fallback for calls on analog or CAS circuits. Calls on ISDN circuits are dropped on fallback.

QUESTION 3:

DRAG DROP
As an instructor at Certkiller .com you are required to click and drag the recommended redundancy method to each layer of the gatekeeper hierarchy. An item may be used more than once.

Answer:

Explanation: Cisco recommends that you use gatekeeper clustering(that is Alternate Gatekeeper) to provide gatekeeper redundancy whenever possible. Use HSRP for redundancy only if gatekeeper clustering is not available in your software feature set.
In any layer of gatekeeper hierarchy, Alternate Gatekeeper method are recommended..

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)

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.
