CompTIA A+ Core 2 (220-1102) — Question 191

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?

Answer options

• A. Channel utilization is oversubscribed.
• B. WPA2 exploits are being leveraged.
• C. The Wi-Fi password is posted on the router.
• D. The customer has a guest network enabled.

Correct answer: D

Explanation

The most probable reason for unauthorized access is that the customer has a guest network enabled, which typically allows users to connect without a password. The other options, such as WPA2 exploits or oversubscribed channels, do not directly lead to open access, and posting the password on the router would not allow access without it.
