DSCP Service Parameters for Cisco Telepresence Audio
Short answer
C DSCP for audio portion of Cisco Telepresence calls
Question
Key Takeaways
The exam tests attention to detail regarding specific configuration field names; the trap is confusing standard video call audio with specialized Telepresence audio parameters.
This question tests knowledge of specific DSCP service parameter naming conventions in CUCM. The correct setting is explicitly named 'DSCP for audio portion of Cisco Telepresence calls' to distinguish it from standard video call audio.
Common mistake: Candidates often select 'DSCP for audio portion of video calls' because they assume all video calls use the same audio DSCP marking, missing the specific distinction for Cisco Telepresence endpoints.
Expert Analysis
Why the Answer Is Correct
The correct answer is C because Cisco Unified Communications Manager (CUCM) maintains distinct service parameters for different media types. Specifically, there is a unique parameter labeled "DSCP for audio portion of Cisco Telepresence calls" designed to handle the differentiated services code point requirements for high-definition Telepresence audio streams separately from standard video.
Why the Other Options Are Wrong
Option A refers to standard video calls, which use a different service parameter than Telepresence-specific setups. Option B applies only to pure audio calls (voice), not mixed media. Option D refers to the video payload itself, not the audio component. Confusing these categories leads to incorrect QoS application.
Community Comment Notes
Community discussion highlights ambiguity in older exam dumps versus current documentation. While some users argue for Option B due to slight wording variations in titles, official Cisco documentation confirms the existence of the specific Telepresence audio parameter. It is crucial to recognize that Telepresence has its own dedicated DSCP settings separate from general video or voice.

Exam Strategy
When studying CUCM service parameters, memorize the exact naming conventions rather than just the concepts. Pay special attention to parameters that differentiate between 'Video Calls', 'Telepresence Calls', and their respective audio portions, as exams often test this granularity.

Dutchviking 👍 2The correct answer should be B. There is no such parameter "DSCP for Audio Portion of CISCO TelePresence Calls", it is called DSCP for Audio Portion of TelePresence Calls. Therefore B is correct: https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/admin/12_0_1/systemConfig/cucm_b_system-configuration-guide-1201/cucm_b_system-configuration-guide-1201_chapter_01000001.html

b3532e4 👍 1This section of service parameters includes clusterwide DSCP values for a wide range of audio and video call types, including DSCP for audio calls, video calls, the audio portion of a video call, TelePresence calls, and the audio portion of a TelePresence call. It is highly recommended that you keep these parameters set to the default value unless a Cisco support engineer instructs otherwise.
