問題文
An engineer plans the network for home workers who will answer calls in the browser rather than on a desk phone. Which figure applies to each of those calls, and how is the network checked before rollout?
選択肢
- Each call in progress needs 3 MB, and the CScan tool is run once for the whole organization because the result does not vary by site.
- A figure of 100 kbps covers every call in progress, and the CScan tool is run from the data center so that the round trip to the media edge is measured, which leaves anything below that figure unable to carry a call.
- This figure is 10 Mbps for every call in progress, and the browser measures the link on its own at the moment of signing in, which leaves anything below that figure unable to connect.
- The figure is 100 kbps for every call in progress, and the CScan tool is run from the networks where the browser will be used so that the computer, the microphone, and the latency are measured together.
