When the store-and-forward method of switching is in use, what part of the Ethernet frame is used to perform an error check?

Source MAC address in the header

Explanation:

Store-and-Forward Switching is a Layer 2 switching method and it means that the LAN switch copies each complete frame into the switch memory buffers and computes a cyclic redundancy check (CRC) for errors. CRC is an error-checking method that uses a mathematical formula, based on the number of bits (1s) in the frame, to determine whether the received frame is errored. If a CRC error is found, the frame is discarded. If the frame is error free, the switch forwards the frame out the appropriate interface port
