Huawei Certified ICT Associate – WLAN (HCIA-WLAN) — Question 15

Which of the following statements about the ESS is true?

Answer options

• A. ESSs are basic WLAN units.
• B. The ESS identifies an AP.
• C. BSSs in an ESS can have different SSIDs.
• D. The ESS is composed of BSSs as basic units and is a method of expanding the BSS range.

Correct answer: C

Explanation

Option C is correct because BSSs in an ESS can indeed have different SSIDs, allowing for more flexibility in network configuration. Option A is incorrect as ESSs are not basic WLAN units but rather an aggregation of multiple BSSs. Option B is misleading since the ESS does not identify a single AP; it encompasses multiple BSSs. Option D is partially true but does not correctly address the specific relationship between SSIDs and BSSs in an ESS.
