CompTIA Security+ (SY0-501) — Question 28

A technician is configuring a wireless guest network. After applying the most recent changes the technician finds the new devices can no longer find the wireless network by name but existing devices are still able to use the wireless network.
Which of the following security measures did the technician MOST likely implement to cause this Scenario?

Answer options

• A. Deactivation of SSID broadcast
• B. Reduction of WAP signal output power
• C. Activation of 802.1X with RADIUS
• D. Implementation of MAC filtering
• E. Beacon interval was decreased

Correct answer: A

Explanation

The correct answer is A, as deactivating SSID broadcast prevents the network name from being visible to new devices, while existing devices that have already connected can still access it. The other options either do not affect SSID visibility or address security in different ways, such as controlling access rather than visibility.
