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?
Answer: D
D A is likely referring to voice-class codec transparent being applied to the dial-peers, but this is only for the initial offer and the response can still be altered by the CUBE with that method. https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/voice/cube/configuration/cube-book/cube-codec-basic.html#id_128259

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.)
Answer: AE
I would go with A and D. Support for Video Suppression Cisco IOS 15.6(2)T Cisco IOS XE Denali 16.3.1 This feature allows pass-through of only audio and application (for T.38 Fax) media types and drops all other media types in SDP. The following commands are introduced: audio forced , voice-class sip audio forced https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/voice/cube/configuration/cube-book/voi-audio-forced.html

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
Answer: D
D is correct. iLBC uses a dynamic payload and cannot be verified with the limited information provided, G.722 is payload type 9 (not listed). G.711a-law and G.711-ulaw are both acceptable, but G.711a-law is payload type 0, which is listed first, therefore is preferred

A customer has Cisco Unity Connections that is integrated with LDAP. As a Unity Connection administrator, you have received a request to change the first name for VM user. Where must the change be performed?
Answer: C
If CUC is integrated with LDAP then the first name can only be changed on the LDAP system. Active Directory is the only choice that is an LDAP system.

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.)
Answer: DE
It's B and E. This can only be done by using DSPs. Hardare MTP and Transcoder through a router. CUCM doesn't have a software transcoders so for sure A cannot be the answer. https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/srnd/collab10/collab10/media.html#77886

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?
Answer: C
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?
Answer: A
Untrue. Region1 has a maximum permitted bandwidth of 60kbps to other devices in Region1, not 64kbps. Even if it was 64kbps though, it would still be G.722 as it is listed higher in the Audio Codec Preference list, which uses the FIRST codec in the list that is within the bandwidth threshold in a TOP DOWN fashion, NOT the highest permitted bandwidth. It's A.
