Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 36

The network administrator wishes to forward data over an Eth-trunk, however associated member interfaces operate at different rates. In terms of the resulting behavior, which of the following is true?

Answer options

• A. The two switches will not be able to communicate.
• B. The higher rate member interfaces may incur packet loss.
• C. The Eth-Trunk will work normally.
• D. The lower rate member interfaces may incur packet loss.

Correct answer: D

Explanation

In an Eth-trunk with member interfaces operating at different speeds, the lower rate interfaces will experience packet loss because they cannot handle the higher throughput being sent through the trunk. The higher rate interfaces may not lose packets, but they will not be able to fully utilize their speed advantage, leading to inefficiencies. Therefore, option D is the correct choice, while the other options misrepresent the effects of this configuration.
