CompTIA A+ Core 2 (220-1102) — Question 137

A technician is working to resolve a Wi-Fi network issue at a doctor's office that is located next to an apartment complex. The technician discovers that employees and patients are not the only people on the network. Which of the following should the technician do to BEST minimize this issue?

Answer options

• A. Disable unused ports.
• B. Remove the guest network.
• C. Add a password to the guest network.
• D. Change the network channel

Correct answer: C

Explanation

Adding a password to the guest network is the most effective way to restrict unauthorized access, ensuring that only those who know the password can connect. Disabling unused ports does not directly affect Wi-Fi access, removing the guest network eliminates access for legitimate users, and changing the network channel may improve performance but won't prevent unauthorized access.
