Hi!
I'm quite sure the answers are B and C.
Answer:
Captive portal.
Explanation:
A Wi-Fi can be defined as a wireless local area network that allows network devices such as access points (APs), computers (both laptops and desktops), smartphones, smart televisions, etc., to communicate with each other wirelessly over a short-ranged network. It is a standard communication network that uses radio waves to establish a channel (medium) between multiple network devices.
In this scenario, when Flavio first connects to a Wi-Fi, a webpage appears requiring him to first agree to an Acceptable Use Policy (AUP) before continuing. Thus, the type of access point (AP) he encountered is a captive portal.
A captive portal can be defined as a webpage that's been designed on a networking device to be viewed and interacted with by the user of a public-access network such as a Wi-Fi, before he or she is granted an access to the network (internet).
