The correct answer is B. G0/0/3 of SWA is a designated port. C. G0/0/3 of SWB is an alternate port. D. G0/0/2 of SWA is a designated port. In RSTP (Rapid Spanning Tree Protocol), G0/0/3 of SWB is an Alternate Port because it provides a redundant path to the root bridge, while G0/0/3 of SWA is a Designated Port, forwarding traffic away from the root bridge. Similarly, G0/0/2 of SWA is also a Designated Port because…

Explanation
In RSTP (Rapid Spanning Tree Protocol), G0/0/3 of SWB is an Alternate Port because it provides a redundant path to the root bridge, while G0/0/3 of SWA is a Designated Port, forwarding traffic away from the root bridge. Similarly, G0/0/2 of SWA is also a Designated Port because it forwards traffic to other segments of the network. Alternate Ports are used to provide backup paths, while Designated Ports are the forwarding ports on a given segment.
