Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 41
A collaboration engineer must configure Cisco Unified Border Element to support up to five concurrent outbound calls across an Ethernet link with a bandwidth of
160 kb to the Internet Telephony Service Provider.
Which set of commands allows the engineer to complete the task without compromising voice quality?

Correct answer: A
Explanation
The correct answer A sets up the dial-peer without specifying a codec, allowing the system to choose the most suitable one for voice quality. Options B, C, and D specify codecs that may not meet the bandwidth requirements or could compromise voice quality with the limited bandwidth available, making them less optimal for this configuration.
