What should Alice do first when she gets to her hotel after a long flight and she cannot connect to the hotel WiFi?

A Make sure airplane mode is off.

In some newer operating system versions, you can enable WiFi after turning on airplane mode but this question (and the exam) doesn’t go that deeply into it Airplane mode turns off WiFi and other signals in the laptop. If you put your laptop in airplane mode at the beginning of a flight, it’s easy to forget that you need to turn it back on.
