CompTIA Network+ (N10-007) — Question 116

A home user has purchased a new smart TV to stream online video services. The smart TV is unable to connect to the wireless network after several attempts.
After returning from vacation, the home user tries again and can connect the TV to the wireless network. However, the user notices a laptop is no longer able to connect to the network. Which of the following is the MOST likely cause?

Answer options

• A. The DHCP scope has been exhausted.
• B. The security passcode has been changed.
• C. The SSID is hidden.
• D. The AP configuration was reset.

Correct answer: A

Explanation

The most likely cause is that the DHCP scope has been exhausted, meaning there are no available IP addresses for the laptop to connect. If the DHCP server assigns an IP address to the smart TV, it could leave no IP addresses for the laptop. The other options are less likely; if the security passcode were changed, neither device would connect, and a hidden SSID or reset AP configuration would not specifically affect only the laptop.
