CCNA: Cisco Certified Network Associate — Question 920

What is the purpose of an SSID?

Answer options

• A. It identifies an individual access point on a WLAN.
• B. It differentiates traffic entering access points.
• C. It provides network security.
• D. It identifies a WLAN.

Correct answer: D

Explanation

The correct answer is D because an SSID (Service Set Identifier) is used to identify a specific Wireless Local Area Network (WLAN). Option A is incorrect as it implies a narrower identification of individual access points rather than the network as a whole. Option B misrepresents the role of SSID, as it does not differentiate traffic. Option C is also incorrect because while security may be associated with networks, SSID itself does not provide security.
