CompTIA Network+ (N10-008) — Question 438

A bank installed a new smart TV to stream online video services, but the smart TV was not able to connect to the branch Wi-Fi. The next day, a technician was able to connect the TV to the Wi-Fi, but a bank laptop lost network access at the same time. Which of the following is the MOST likely cause?

Answer options

• A. DHCP scope exhaustion
• B. AP configuration reset
• C. Hidden SSID
• D. Channel overlap

Correct answer: A

Explanation

The most likely cause is DHCP scope exhaustion, which occurs when all available IP addresses have been assigned, preventing new devices from connecting to the network. When the technician connected the smart TV, it may have consumed the last available IP address, causing the bank laptop to lose its connection. The other options, such as AP configuration reset, hidden SSID, and channel overlap, do not directly explain the simultaneous loss of access experienced by the laptop.
