Actual exam question for Huawei's H12-811_V1.0 exam
Question #: 80
Topic #: 8
[All H12-811_V1.0 Questions]

A switch needs to forward a frame with the destination MAC address 5489-98EC-F011. Refer to the display mac-address command output. Which of the following statements is true?

Show Suggested Answer Hide Answer
Suggested Answer: C

The MAC address table does not contain an entry for 5489-98EC-F011.

When a switch receives a frame with an unknown destination MAC address, it performs flooding.

Flooding sends the frame out of all interfaces except the one it was received on.

A (Incorrect): The switch does not discard unknown frames; it floods them.

B (Incorrect): No request is sent; flooding occurs instead.

D (Incorrect): ICMP is used for network-layer (IP) communication, not Ethernet switching.

Thus, the correct answer is C (Floods the frame on all interfaces except the incoming one).

I'm going with Option C. Flooding the frame is the best way to ensure it reaches the destination, even if the MAC address isn't in the table.

I'm not sure, but I think the switch should send a request to discover the device with that MAC address, so my answer is B.

Option A is the way to go. If the switch doesn't find the MAC address in its table, it has no choice but to discard the frame.

Cassi: That's right. It just discards the frame if it doesn't have a matching entry.

I agree with Stefany, because the switch floods the frame when it doesn't have a matching entry.

Haha, Option D is a classic! The switch sending an ICMP unreachable message, that's a good one.

So, the frame will eventually reach the device with MAC address 5489-98EC-F011 through flooding.
