How can the location setting be modified to resolve poor call quality?
A.
No adjustment to location setting is needed
B.
Mark the bandwidth between the locations as unlimited
C.
Decrease the audio bandwidth setting
D.
Remove the audio bandwidth setting
Sure?
In my opinion locations have nothing to do with call quality, they only blocking calls if bandwith exceeds…CAC
Should be A

No you are right, decreasing would help because lesser calls go through.sorry

I understood all of the questions very easily. I scored 96% on my first try. I am definitely going to spread the word among friends and colleagues. Keep up the great work.
Here are some examples:
QUESTION 251
Refer to the exhibit. Which statement about the configuration between the Default and BR regions is true?
A. Calls between the two regions can use either 64 kbps or 8 kbps.
B. Calls between the two regions can use only the G.729 codec.
C. Only 64 kbps will be used between the two regions because the link is “lossy”.
D. Both codecs can be used depending on the loss statistics of the link.
When lossy conditions are high, the G.711 codec will be used.
Answer: B
QUESTION 252
Which statement about H.323 Gatekeeper Call Admission Control is true?
A. Gatekeeper Call Admission Control applies to centralized Cisco Unified Communications deployments that use locations based Call Admission Control.
B. Gatekeeper Call Admission Control applies to distributed Cisco Unified Communications deployments.
C. Gatekeeper Call Admission Control applies only to distributed Cisco Unified Communications Express deployments.
D. Gatekeeper Call Admission Control setting is configured in Cisco Unified Communications Manager.
Answer: B
Explanation:
in distributed call processing deployments on a simple hub-and-spoke topology, you can implement call admission control with a Cisco IOS gatekeeper. In this design, the call processing agent (which could be a Unified CM cluster, Cisco Unified Communications Manager Express (Unified CME), or an H.323 gateway) registers with the Cisco IOS gatekeeper and queries it each time the agent wants to place an IP WAN call.
QUESTION 253
Refer to the exhibit. How many calls can be placed to Cluster B?
A. three G.729 calls
B. one G.711 call
C. one G.711 and three G.729 calls
D. There is no limit for incoming calls to Cluster B.
Outgoing calls are limited to one G.711 and three G.729 calls.
Answer: A
QUESTION 254
Refer to the exhibit. You have configured transcoder resources in both an IOS router and a Cisco Unified Communications Manager. When you review the configurations in both devices the IP addresses and transcoder names are correct, but the transcoder is failing to register with the Cisco Unified Communications Manager.
Which command needs to be edited to allow the transcoder to register properly?
A. The associate profile and dsp farm profile numbers need to match associate ccm 2 command.
B. The associate ccm 2 priority 1 command needs to be changed so the ccm value matches identifier 1 in the sccp ccm 10.1.1.1 command.
C. The sccp ccm group number needs to match the associate ccm 2 command.
D. The maximum sessions command must match the number of codecs configured under the dsp farm profile.
E. The sccp ccm group number must match the voice-card number.
Answer: B
Explanation:
The value of the IP address should match the IP address in the ip source-address command.
QUESTION 255
If your IP telephony administrator asks you to configure a local zone for your dial plan to control the volume of calls between two end points in a centralized multisite environment, which two types of Call Admission Control can be implemented? (Choose two.)
A. locations based
B. automated alternate routing
C. gatekeeper based
D. SRST
E. Cisco Unified Communications Manager based
Answer: AB
Explanation:
Location-based call admission control (CAC) manages WAN link bandwidth in Cisco Unified Communications Manager. Automated alternate routing (AAR) provides a mechanism to reroute calls through the PSTN or other network by using an alternate number.
QUESTION 256
Which statement is correct about AAR?
A. The end users sees, “Network Congestion Rerouting?” but AAR is otherwise transparent to the end user and works without user intervention.
B. AAR will display “not enough bandwidth” on the IP phone while it reroutes the call.
C. AAR allows calls to be rerouted because of insufficient Cisco Unified Border Element controlled bandwidth to an ITSP.
D. AAR allows calls to be rerouted due to insufficient gatekeeper controlled IP WAN bandwidth.
Answer: A
Explanation:
Automated alternate routing (AAR) provides a mechanism to reroute calls through the PSTN or other network by using an alternate number when Cisco Unified Communications Manager blocks a call due to insufficient location bandwidth. With automated alternate routing, the caller does not need to hang up and redial the called party.
QUESTION 257
Refer to the exhibit. A user in RTP calls a phone in San Jose during congestion with Call Forward No Bandwidth (CFNB) configured to reach cell phone 4085550150. The user in RTP sees the message “Not Enough Bandwidth” on their phone and hears a fast busy tone.
Which two conditions can correct this issue? (Choose two.)
A. The calling phone (RTP) needs to have AAR Group value of AAR under the AAR Settings.
B. The called phone (San Jose) needs to have AAR Group value of AAR under the AAR Settings.
C. The calling phone (RTP) needs to have the AAR destination mask of 914085550150 configured under the AAR Settings.
D. The calling phone (RTP) needs to have the AAR destination mask of 4085550150 configured under the AAR Settings.
E. The called phone (San Jose) needs to have the AAR destination mask of 914085550150 configured under the AAR Settings.
F. The called phone (San Jose) needs to have the AAR destination mask of 4085550150 configured under the AAR Settings.
Answer: BF
Explanation:
Automated alternate routing (AAR) provides a mechanism to reroute calls through the PSTN or other network by using an alternate number when Cisco Unified Communications Manager blocks a call due to insufficient location bandwidth. With automated alternate routing, the caller does not need to hang up and redial the called party.
QUESTION 258
Which two statements describe RSVP-enabled locations-based CAC? (Choose two.)
A. RSVP can be enabled selectively between pairs of locations.
B. Using RSVP for CAC simply allows admitting or denying calls based on a logical configuration that is ignoring the physical topology.
C. RSVP is topology aware, but only works with full mesh networks.
D. An RSVP agent is a Media Termination Point that the call has to flow through.
E. RSVP and RTP are used between the two endpoints.
Answer: AD
Explanation:
The RSVP policy that is configured for a location pair overrides the default interlocation RSVP policy that configure in the Service Parameter Configuration window. RSVP supports audio, video, and data pass-through. Video data pass-through allows video and data packets to flow through RSVP agent and media termination point devices
QUESTION 259
You are deploying a remote office setup that connects with Cisco Unity Communications Manager at a hub location. You have an available dedicated bandwidth of 20% from the 2-Mb/s WAN circuit for VoIP that supports a maximum of 17 calls.
Which codec do you configure in Cisco Unity Communications Manager to achieve this?
A. G.722
B. G.711
C. G.729
D. iSAC
E. GSM-FR
F. iLBC
Answer: C
QUESTION 260
How do RSVP-enabled locations differ from Cisco Unified Communications Manager locations?
A. RSVP is configured in the ISR independent of Cisco Unified Communications Manager.
B. RSVP enables AAR within Cisco Unified Communications Manager.
C. RSVP is topology aware.
D. RSVP is configured in Cisco Unified Communications Manager independent of the ISR.
