Question #54

Regarding loop protection, which of the following is correct? (Multiple choice)

A. Link blocking or one-way link may cause loops

B. After the loop protection function is enabled, when the BPDU stored on the port ages, the loop protection takes effect.

C. If the role of the root port changes, it will change to the Discarding state and will not forward messages, so as not to form a loop in the network. The Discarding state will be maintained until the port receives a BPDU again and becomes a root port again.

D. In MSTP, this function is valid for root ports, alternate ports, and backup ports.
