Question

A) Cut-Through Switching
B) Store-and-Forward Switching
C) Fast Ethernet Switching
D) VLAN Switching

Answer 1

Store-and-Forward Switching forwards a frame only after all of the frame is received and checked for errors.

Step-by-step explanation:

Store-and-Forward Switching

forwards a frame only after all of the frame is received and checked for errors. In this method, the switch receives the entire frame and performs a CRC (Cyclic Redundancy Check) to verify if any errors are present. If the frame is error-free, it is then forwarded to the destination. If errors are detected, the frame is discarded. This method ensures that only error-free frames are forwarded.
