Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 133

An engineer implements a new Cisco UCM based telephony system per these requirements:
✑ The local Ethernet bandwidth is sized based on the total bandwidth per call.
✑ A G.736 codec is used.
✑ The bit rate is 64 kbps.
✑ The codec sample interval is 10 ms.
✑ The voice payload size is 160 bytes per 20 ms.
What should the size of the Ethernet bandwidth be per call?

Answer options

Correct answer: D

Explanation

The correct answer is D because the total bandwidth per call is calculated by considering the codec characteristics and the payload size. The other options do not account for the required bandwidth correctly based on the given parameters, leading to lower calculations.
