Your customer has implemented a multipoint control unit to allow conferencing between existing
Cisco Unified Video Advantage users. The multipoint control unit appears to be properly
configured, but users are complaining that when they conference they get audio but no video.
What is the most likely cause?

You are troubleshooting why a user cannot make calls to the PSTN. You are reviewing trace files
and you have found where the user’s IP phone initiates the call but you never see the call go out
the gateway. What is the next step in troubleshooting this issue?

You have two Cisco Unified CallManager clusters each using endpoint authentication. You have
moved a small group of users from Cluster 1 to Cluster 2 and now their phones are failing to
register with Cluster 2. Each phone displays the error message “failure to authenticate on the CTL
file”.
Which step should be taken to resolve this issue?

Your company has recently installed a Cisco Unified CallManager cluster and a Cisco Unity voice
mail platform. You have received complaints from users that the red MWI light never comes on,
even when there are new voice-mail messages in the voice mailboxes. Which two steps must be
taken to resolve this issue? (Choose two.)

You have developed a dial plan for a Cisco Unifed CallManager 5.0 solution. All the route patterns,
partitions, calling search spaces, and translation rules have been configured. Before starting up
the system you wish to test the dial plan for errors.
Which Cisco Unifed CallManager tool will simplify this testing?

In order for a third-party SIP phone to register with a Cisco Unified CallManager cluster, which
three configuration parameters must match between the phone and the cluster? (Choose three.)

You have configured an ISR at a branch office to register as an Enhanced IOS media resource
providing transcoding services. The transcoder has not been placed into a media resource group.
Which statement best describes which devices will be able to utilize this transcoder?

You have configured the Enable Keep Alive check box under Trace Filter Settings. How does this
change the trace output?

You have just obtained a list of the following options:
All Patterns
Unassigned DN
Call Park
Conference
Directory Number
Translation Pattern
Call Pickup Group
Route Pattern
Message Waiting
Voice Mail
Attendant Console
What have you selected in order to produce this list?

Refer to the exhibit. You have received a trouble ticket that two engineers at the HQ site tried to
conference at a user location at the Branch site and the ad-hoc conference failed.

Further investigation reveals that the remote user can occasionally be conferenced in. Phones are
configured to use G.711 for intra-site calls and G.729 for inter-site calls. All phones at the remote
site are configured to use MRGL_Branch, which contains only the media resource group named
BRANCH.
What should be done to correct this issue?
