Question

What is a function of store-and-forward switching?

A It reduces latency by eliminating error checking within the frame
B It produces an effective level of error-free network traffic using CRCs.
C It buffers frames and forwards regardless of errors within the frames.
D It forwards a frame by checking only the destination MAC address

Explanation

Store-and-forward switching reads the entire frame, verifies it with the Frame Check Sequence (CRC-based error detection), and forwards only frames that pass the integrity check. This helps prevent corrupted frames from being propagated, producing a more error-free flow of traffic across the network.
