Dennis is driving a car with his family onboard. His children are sitting on the backseat. They have a tablet and want to watch a video on the Internet. What can Dennis do that will allow the children to watch a video on the Internet while in the car?

Answer: d. Enable a hotspot on his smartphone.

Explanation:

By enabling a WiFi hotspot on his smartphone, Dennis will essentially make his phone a WiFi router (device) which devices can then connect to.

As they connect, Dennis will switch on his mobile data to enable his phone to connect to his network provider's internet service.

Once connected the phone will then share this internet with the devices that are connected to it's WiFi.
