When the store-and-forward method of switching is in use, what part of the Ethernet frame is used to perform an error check?
- CRC in the trailer
- source MAC address in the header
- destination MAC address in the header
- protocol type in the header
Answers Explanation & Hints: The cyclic redundancy check (CRC) part of the trailer is used to determine if the frame has been modified during transit. If the integrity of the frame is verified, the frame is forwarded. If the integrity of the frame cannot be verified, then the frame is dropped.
