CCNA: Cisco Certified Network Associate — Question 566

If a switch port receives a new frame while it is actively transmitting a previous frame, how does it process the frames?

Answer options

• A. The new frame is delivered first, the previous frame is dropped, and a retransmission request is sent
• B. The previous frame is delivered, the new frame is dropped, and a retransmission request is sent
• C. The new frame is placed in a queue for transmission after the previous frame
• D. The two frames are processed and delivered at the same time

Correct answer: C

Explanation

The correct answer is C because switches typically queue incoming frames for transmission until the current frame is completed. Options A and B incorrectly suggest that one of the frames is dropped, and option D is incorrect as switches do not process two frames at once due to their design.
