Question

question 17 which frame forwarding method receives the entire frame and performs a crc check to detect errors before forwarding the frame? cut - through switching fast - forward switching store - and - forward switching fragment - free switching

Explanation:

Store - and - forward switching waits to receive the entire frame, then performs a cyclic redundancy check (CRC) to detect errors before forwarding the frame. Cut - through switching starts forwarding before receiving the whole frame. Fast - forward is another name for cut - through. Fragment - free switching checks the first 64 bytes (a common size for a collision fragment) but not the whole frame like store - and - forward.

Answer:

C. store - and - forward switching
