CCNA: Cisco Certified Network Associate — Question 967

What does a switch search for in the CAM table when forwarding a frame?

Answer options

• A. source MAC address and aging time
• B. destination MAC address and flush time
• C. source MAC address and source port
• D. destination MAC address and destination port

Correct answer: D

Explanation

The correct answer is D because a switch examines the destination MAC address in the CAM table to determine the appropriate port for forwarding the frame. The other options incorrectly reference source MAC addresses or irrelevant timing parameters that are not used in the frame forwarding process.
