Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 39

What will the destination MAC address be at the moment a frame is transmitted by the host, when the router is the IP destination?

Answer options

• A. The MAC address of the switch.
• B. The MAC address of the router interface G0/0/0.
• C. The MAC address of the host.
• D. The destination MAC address will be a broadcast MAC address.

Correct answer: D

Explanation

The correct answer is D because when the host does not know the MAC address of the router, it will use a broadcast MAC address to reach all devices on the local network. Options A, B, and C are incorrect because the frame cannot be sent to the switch's MAC, the router's MAC, or the host's MAC if the destination is the router.
