CompTIA A+ Core 2 (220-1002) — Question 30

A small business has an open wireless network so vendors can connect to the network without logging in. The business owners are concerned that a nearby company is connecting and using the wireless connection without permission.
If the small business requires that the network remain open, which of the following configuration settings should be changed to address these concerns?

Answer options

• A. Default SSID
• B. MAC filtering
• C. Power levels
• D. Content filtering
• E. Firewall

Correct answer: C

Explanation

Adjusting the power levels of the wireless network can limit the signal range, reducing the likelihood of unauthorized access from nearby companies. The other options, such as MAC filtering, do not effectively secure an open network, and changing the default SSID, content filtering, or firewall settings would not directly address the concern of unauthorized access while keeping the network open.
