Huawei Certified ICT Associate – Data Center Network (HCIA-DCN) — Question 188

When an AP and an AC are located on different Layer 3 networks, which of the following methods is recommended for the AP when discovering the AC?

Answer options

• A. DNS
• B. Broadcast
• C. DHCP
• D. Manually specified on the AP

Correct answer: A

Explanation

The correct answer is A, as DNS can resolve the AC's address, facilitating communication across different Layer 3 networks. Options B and C are not suitable because broadcast messages do not cross Layer 3 boundaries, and DHCP typically does not provide AC information. Manually specifying the AC (D) is not practical for dynamic environments.
