A coffee shop owner wants to restrict internet access to only paying customers by prompting them for a receipt number. Which of the following is the best method to use given this requirement?
B. Captive portal
Explanation:
A captive portal is a web page that users are redirected to when they connect to a network. It is commonly used in coffee shops, hotels, and other public places to enforce policies like requiring users to enter a receipt number, agree to terms of use, or log in before granting internet access.
Other Options:
A. WPA3: A secure Wi-Fi encryption standard, but it does not offer functionality to prompt for receipt numbers or other user-specific authentication.
C. PSK (Pre-Shared Key): Uses a shared password for network access but cannot handle individual receipt-based authentication.
D. IEEE 802.1X: A port-based network access control protocol typically used in enterprise environments with authentication servers, but it is too complex and not suitable for this requirement.
B Captive Portal
This will allow the coffee shop to restrict internet access by redirecting users to a web page where they must enter the receipt information to gain access.
