220-1102 Question #111: Real Exam Question with Answer & Explanation

Question

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?

Options

• ADisable unused ports.
• BRemove the guest network
• CAdd a password to the guest network
• DChange the network channel.

Explanation

To prevent unauthorized users from an adjacent apartment complex from accessing the doctor's office Wi-Fi, the technician should add a strong password to the guest network. This restricts access while still allowing legitimate guests to connect securely.

Common mistakes.

• A. Disabling unused ports applies to wired networks, not Wi-Fi, and is irrelevant to unauthorized Wi-Fi access.
• B. Removing the guest network would address unauthorized access but would also inconvenience legitimate patients and employees who need guest access.
• D. Changing the network channel helps optimize Wi-Fi performance by reducing interference, but it does not prevent unauthorized users from connecting if the network is open or the password is known.

Concept tested. Wireless network security - guest access
