Q1. Video calls using 384 kbps need to be supported across a gatekeeper-controlled trunk. What value should be entered into the gatekeeper to support this bandwidth?
A. 768 kbps
B. 384 kbps
C. 512 kbps
D. 192 kbps
Answer: B
Explanation:
Incorrect Answer: A, C, D A 384-kb/s video call may comprise G.711 at 64 kb/s (for audio) plus 320 kb/s (for video). This sum does not include overhead. If the audio codec for a video call is G.729 (at 24 kb/s), the video rate increases to maintain a total bandwidth of 384 kb/s. Link:

Which device configuration option will allow an administrator to assign a device to specific rights for making calls to specific DNs?
A. Media Resource Group List
B. Device Pool
C. Location
D. AAR Group
E. Calling Search Space
Answer: E
Explanation:
A partition comprises a logical grouping of directory numbers (DNs) and route patterns with similar reachability characteristics. Devices that are typically placed in partitions include DNs and route patterns. These entities associate with DNs that users dial. For simplicity, partition names usually reflect their characteristics, such as "NYLongDistancePT," "NY911PT," and so on. A calling search space comprises an ordered list of partitions that users can look at before users are allowed to place a call. Calling search spaces determine the partitions that calling devices, including IP phones, softphones, and gateways, can search when attempting to complete a call.
Q3. Which action configures CAC utilizing only Cisco Unified Communications Manager software?
A. Configure Cisco Unified Communications Manager regions.
B. Configure Cisco Unified Communications Manager locations.

Answer: B
Q4. When an incoming PSTN call arrives at an H.323 gateway, how does the called number get normalized to an internal directory number in Cisco Unified Communications Manager?
A. Normalization is done by configuring the significant digits for inbound calls on the H.323 gateway configuration in Cisco Unified Communications Manager.
B. Normalization is done using route patterns.
C. Normalization is done using the gateway incoming calling party prefixes based on number type.
D. Normalization is achieved by local route group that is assigned to the H.323 gateway.
Answer: A
Q5. Which option describes the reason that transcoding resources are added in Cisco Unified Communications Manager?

Q10. 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
