• Question 202:

  The following statements describe the icons' functions displayed in the exhibit. The GK icon can be clicked to view the output of the show gatekeeper endpoint command. The CallManager cluster can be clicked to see the trunk configuration screens. The X of each popup can be clicked to return to the item.

  In order to support three local zones West, East and EMEA, the 10.1.110.1 router is configured with a gatekeeper. After issuing the show gatekeeper endpoints command, you find that the West zone device is lost. Please choose the proper measure that should be taken to the configuration in the CallManager for it to register with the gatekeeper of the zone West.

  

  A. Restart the callmanger so it can register with the gatekeeper
  B. Change the Device Name to be the IP address of the gatekeeper in the CallManager Trunk Configuration page
  C. Set the Terminal Type to terminal in the Gatekeeper Information field of the Trunk Configuration
  D. Configure a zone name on the CallManager trunk
  D. Configure a zone name on the CallManager trunk

• Question 203:

  You must integrate a third-party H.323 system with your existing Cisco Unified Communications Manager cluster. When you create an H.323 trunk from the cluster, calls from the cluster to the third- party H.323 system are failing. The vendor

  of the third-party H.323 device has confirmed that the 323 call setup time must be reduced.

  Which two approaches reduce the call setup time from Cisco Unified Communications Manager to the third-party H.323 device? (Choose two.)

  A. Implement a software MTP.
  B. Implement a hardware MTP.
  C. Implement transcoding with the router DSP resources.

  B. Implement a hardware MTP.

• Question 204:

  Refer to the exhibit.

  

  A second Cisco Unified Communications Manager server of 10.10.10.101 was added along with the existing Cisco Unified CM server of 10.10.10.100. When Cisco Unified CM 10.10.10.100 is unavailable, the branch gateway fails to register. Which configuration change is needed to register the gateway to either Cisco Unified CM server?

  A. Add the command ccm-manager redundant-host 10.10.10.101.
  B. Add the command MGCP.
  C. Increase the amount of bandwidth allocated in the low latency queuing for MGCP signaling traffic.
  D. Remove the gatekeeper command because MGCP conflicts with H.323 on the voice gateway.
