Huawei Certified ICT Associate – Data Center Network (HCIA-DCN) — Question 135

Which of the following statements about an Eth-Trunk in LACP mode is true?

Answer options

• A. The number of active interfaces cannot be set.
• B. A maximum of four active interfaces are supported.
• C. Devices at both ends exchange LACPDUs.
• D. All active interfaces participate in data forwarding and load balance traffic.

Correct answer: D

Explanation

The correct answer is D because in an Eth-Trunk configured in LACP mode, all active interfaces do indeed participate in both data forwarding and load balancing. Option A is incorrect as the number of active interfaces can be configured. Option B is wrong because LACP can support more than four active interfaces. Option C is true but does not directly address the operation of the Eth-Trunk in terms of load balancing.
