CCNA: Cisco Certified Network Associate — Question 830

What is a characteristic of an SSID in wireless networks?

Answer options

• A. intercepts data threats before they attack a network
• B. encodes connections at the sending and receiving ends
• C. broadcasts a beacon signal to announce its presence by default
• D. identifies an access point on a WLAN

Correct answer: C

Explanation

The correct answer is C, as an SSID typically broadcasts a beacon signal to let devices know it is available for connections. Option A is incorrect because SSIDs do not provide security against data threats. Option B is also wrong since SSIDs do not encode connections; that is the role of encryption protocols. Option D, while related, does not capture the characteristic of broadcasting a signal.
