Huawei Certified ICT Associate – SD-WAN (HCIA-SD-WAN) — Question 4

In Huawei’s smart roaming solution, which of the following methods can be used by a WAC to discover and maintain neighboring AP entries of STAs?

Answer options

• A. The WAC obtains such entries using 802.11v
• B. The AP listens to the Probe frames sent by STAs
• C. The AP periodically and proactively scans neighboring APs of STAs
• D. STAs proactively report neighboring AP information

Correct answer: C

Explanation

The correct answer is C because the AP actively scans neighboring APs to gather updated information about them. Options A and B do not provide a method for proactive discovery, while option D relies on STAs to report information, which is not as effective as the AP's proactive scanning.
