220-1102 Question #314: Real Exam Question with Answer & Explanation

Question

A technician is investigating unauthorized Wi-Fi access on a customer's home network. Individuals are able to access the customer's Wi-Fi network without a password. Which of the following is the MOST likely reason this situation is occurring?

Options

• AChannel utilization is oversubscribed.
• BWPA2 exploits are being leveraged.
• CThe Wi-Fi password is posted on the router.
• DThe customer has a guest network enabled.

Explanation

The most likely reason for unauthorized Wi-Fi access without a password on a home network is that a guest network has been enabled.

Common mistakes.

• A. Channel utilization being oversubscribed leads to poor Wi-Fi performance, not open or unauthorized access without a password.
• B. While WPA2 exploits exist, they typically involve bypassing an existing password, and are generally less common than a misconfigured or open guest network that requires no password.
• C. A Wi-Fi password posted on the router would imply that a password is still required for access, which contradicts the scenario of access "without a password."
