CompTIA Network+ Exam Review

Answer - C - The store-and-forward switching mode provides the highest level of integrity and error-free transport.

Key Takeaway: The store-and-forward switching method copies the entire frame on the onboard buffers and does the cyclic redundancy check (CRC). The frame is discarded if it does not contain any errors. The switch looks up the destination address in its MAC address table and selects the outgoing interface. The frame is then forwarded to the destination.
