As shown in the figure, SWB and SWC enable STP. SWC is the root, and SWA does not enable STP. Initially, link 2 is not connected. PCB can send data to PCA. If link 1 fails at this time, the maintenance personnel connect link 2. which of the following statement about the recovery process of the data transmission service from PCB to PCA is correct? (Multiple choice)

A. Since SWA does not enable STP, service recovery needs to wait for the MAC address of SWC to age, which takes 300 seconds by default.

B. SWA port EO/1 will not send TCN BPDU to SWC after link is interrupted

C. SWB's port EO/1 needs to wait for the default 30 seconds to enter the forwarding state, so the service recovery from PCB to PCA takes a total of 30 seconds by default.

D. SWB's port EO/1 enters the Forwarding state, triggering a topology change process, which shortens the MAC address aging time. Therefore, the service recovery from PCB to PCA takes a total of 45 seconds by default.
