Huawei Certified ICT Associate – Data Center Network (HCIA-DCN) — Question 102

When a switch receives a unicast data frame, if the destination MAC address of the data frame can be found in the MAC address table of the switch, the data frame is definitely forwarded through the port corresponding to the MAC address.

Answer options

Correct answer: B

Explanation

The correct answer is B because even if the MAC address is in the table, the switch may not forward the frame if the port is down or if the MAC address is associated with multiple ports due to a loop or other network topology factors. Therefore, it is not definitive that the data frame will be forwarded through the specified port.
