Explanations

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?

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.

A.

Based on the given information, the most likely cause for the laptop being unable to connect to the wireless network is that the DHCP scope has been exhausted.

DHCP (Dynamic Host Configuration Protocol) is a protocol used by routers to automatically assign IP addresses to devices that connect to the network. The DHCP server in the router has a limited range of IP addresses, called the DHCP scope, that it can assign to devices.

In this scenario, when the smart TV was initially unable to connect to the wireless network, it is possible that it was attempting to obtain an IP address from the DHCP server, but the DHCP scope had been exhausted. This means that there were no more IP addresses available for the DHCP server to assign to the smart TV.

However, when the user returned from vacation and tried again to connect the smart TV to the wireless network, it is possible that the DHCP scope had been refreshed and new IP addresses were available for the DHCP server to assign.

As a result, when the laptop tried to connect to the network, it was unable to obtain an IP address from the DHCP server due to the exhausted DHCP scope. Therefore, the most likely cause of the laptop being unable to connect to the network is the DHCP scope being exhausted.

Option B (the security passcode has been changed) and Option C (the SSID is hidden) are less likely causes, as they would not affect the laptop's ability to connect to the network after the smart TV had successfully connected. Option D (the AP configuration was reset) is also less likely, as it would require intentional action by someone to reset the AP configuration.
