You are adding regions in Cisco Unified Communications Manager.
Which codec(s) are selected when a call is placed if you set up the max audio bit rate to use 8 kbps?
- A . G.729
- B . G.729 and G.711ulaw
- C . G.711ulaw and G.711alaw
- D . G.722
How can an administrator stop Cisco Unified Communications Manager from advertising the OPUS codec for recording enabled devices?
- A . Route recorded calls through Cisco Unified Border Element because it does not support OPUS.
- B . Go to the phone’s configuration page and set ג Advertise OPUS Codec ג to be ג false ג .
- C . Integrate the Cisco Unified CM with 3 recording solution that does not support OPUS.

An engineer must manually provision a Cisco IP Phone 8845 using SIP.
Which two fields must be configured for a successful provision? (Choose two.)
- A . location
- B . media resources group list
- C . SIP profile
- D . CSS
- E . device security profile
Refer to the exhibit.
When making a call to a MRA client, what are the combinations of protocol on each of the different sections A-B-C?
- A . SIP TCP/TLS (A) + SIP TLS (B) + SIP TLS (C)
- B . SIP TCP/TLS (A) + SIP TCP/TLS (B) + SIP TCP/TLS (C)
- C . IP TCP/TLS (A) + SIP TCP/TLS (B) + SIP TLS (C)

An engineer is configuring a Cisco Unified Border Element to allow the video endpoints to negotiate without the Cisco Unified Border Element interfering in the process.
What should the engineer configure on the Cisco Unified Border Element to support this process?
- A . Configure codec transparent on the dial peers.
- B . Configure a transcoder for video protocols.
- C . Configure a hardcoded codec on the dial peers.
- D . Configure pass-thru content sdp on the voice service.
Due to service provider restriction, Cisco UCM cannot send video in the SDP.
Which two options on Cisco UCM are configured to suppress video in the SDP in outgoing invites? (Choose two.)
- A . Set Video Bandwidth in the Region settings to 0.
- B . Check the Send send-receive SDP in mid-call INVITE check box on the SIP trunk SIP profile.
- C . Change the Video Capabilities dropdown on the endpoint to Disabled.
- D . Add the audio forced command to voice service VoIP on the Cisco Unified Border Element.
- E . Check the Retry Video Call as Audio on the SIP trunk.
A Cisco IP Phone 7841 that is registered to a Cisco UCM with default configuration receives a call setup message.
Which codec is negotiated when the SDP offer includes this line of text?
m=audio 49181 RTP/AVP 0 8 97
- A . G.711alaw
- B . iLBC
- C . G.722
- D . G.711ulaw
Endpoint A is attempting to call endpoint B. Endpoint A only supports G.711ulaw with a packetization rate of 20 ms, and endpoint B supports packetization rate of 30 ms for G.711ulaw.
Which two media resources are allocated to normalize packetization rates through transrating? (Choose two.)
- A . software transcoder on Cisco UCM
- B . hardware transcoder on Cisco IOS Software
- C . software MTP on Cisco IOS Software
- D . software MTP on Cisco UCM
- E . hardware MTP on Cisco IOS Software
An engineer with ID0123456789 is designing a new dial plan for a customer that has offices in several countries on four continents around the world. This client also wants to integrate with a Microsoft Lync backend.
Which dial plan type does the engineer recommend?
- A . H.323
- B . SIP URI
- C . E.164
- D . TEHO
Refer to the exhibit.
An engineer is troubleshooting a codec negotiation issue where both endpoints that are involved in the call support the codecs listed in the exhibit.
Which audio codec is selected if a call between two endpoints in Region1 is placed?
- A . G.722
- B . G.729
- C . G.711a
- D . G.711u
