問題文
An engineer must state what the transport advertises through the link layer discovery protocol so that the adapters on the hosts classify their traffic consistently with the switch. Which set of values is advertised?
選択肢
- A selector of UDP, a protocol identifier of 4791, and a priority of 3.
- The maximum transmission unit, the negotiated link speed, and the forward error correction mode, so that a mismatch at the physical layer is detected before the transport is used.
- A selector of TCP, a protocol identifier of 4791, and a priority of 6, because the notification packets are the part of the exchange that has to be protected and the reliable transport is what carries the payload between the adapters in this profile.
- The switch identifier and the port identifier only, so the adapters learn where they are attached.
