Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 167

A network administrator with ID0123456789 has determined that a WAN link between two Cisco UCM clusters supports only 1 Mbps of bandwidth for voice traffic.
How many calls does this link support if G.711 as the audio codec is used?

Answer options

• A. 12
• B. 13
• C. 15
• D. 16

Correct answer: A

Explanation

Using G.711 codec, each call requires approximately 64 Kbps of bandwidth. Given a 1 Mbps link, dividing 1000 Kbps by 64 Kbps per call results in a maximum of 15.625 calls. However, since only whole calls can be made, this rounds down to 12 calls, making option A the correct answer. Options B, C, and D exceed the available bandwidth capacity.
