問題文
The same guide explains the parameters that decide the marking of packets and what a link between two locations is for. Which of the parameters covers the audio and the video of a video call together, and which calls does the audio bandwidth of a link cover?
選択肢
- Parameters meant for the audio inside a video call cover them together regardless of what the endpoint supports, and the audio bandwidth of a link covers the calls for voice and the calls that carry a fax.
- Audio inside a video call has its own parameter that covers them together whatever the endpoint supports, while the audio bandwidth of a link covers the calls for voice, with a fax counted under the video bandwidth.
- Covering them together is the parameter for video calls unless the endpoint supports the parameter meant for the audio inside a video call, while the audio bandwidth of a link covers the calls for voice, with a fax counted under the video bandwidth.
- The parameter for video calls covers them together unless the endpoint supports the parameter meant for the audio inside a video call, and the audio bandwidth of a link covers the calls for voice and the calls that carry a fax.
