Q1661: What happens when a destination device responds to a frame in a switch?
- A: The switch adds the source MAC address and port to the MAC address table.
- B: The switch deletes the MAC address from the table.
- C: The switch ignores the response.

Q1664: Fill in the blank: The store-and-forward method of switching checks frames for errors using a _______ known as a cyclic redundancy check (CRC).
- A: Mathematical error-checking mechanism

Q1665: How does the cut-through method of switching differ from the store-and-forward method?
- A: It starts forwarding the frame before the entire frame is received.
- B: It waits for the entire frame to be received before forwarding.
- C: It uses software-based error checking.
- D: It relies on external devices for error checking.

Q1668: How does a switch reduce the number of devices competing for bandwidth?
