Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 368

An engineer with troubleshoots poor voice quality on multiple calls. After looking at packet captures, the engineer notices high levels of jitter. Which two areas does the engineer check to prevent jitter? (Choose two.)

Answer options

• A. The network meets bandwidth requirements.
• B. MTP is enabled on the SIP trunk to Cisco Unified Border Element.
• C. Cisco UBE manages voice traffic, not data traffic.
• D. All devices use wired connections instead of wireless connections.
• E. Voice packets are classified and marked.

Correct answer: A, E

Explanation

Ensuring that the network meets bandwidth requirements (A) is essential for reducing jitter, as insufficient bandwidth can lead to packet delays. Additionally, classifying and marking voice packets (E) helps prioritize them over other types of traffic, which also reduces jitter. The other options do not directly address the issue of jitter in voice quality.
