Drag the authentication modes on the left into their applicable scenarios on the right.

Correct Answer:

Explanation:
A screenshot of a computer AI-generated content may be incorrect.
Comprehensive and Detailed In-Depth Explanation:
1. Portal Authentication:
Scenario:Guests who move frequently and use different types of terminals.
Portal authentication (also known as Web authentication) is commonly used in environments like Wi-Fi hotspots, hotels, and public areas.
Users are redirected to a login page where they enter credentials.
This method is flexible for guests and visitors who may frequently change locations or devices.
Use Case:Wi-Fi access for guests in a corporate environment.
2. MAC Address Authentication:
Scenario:Dumb terminals such as printers and fax machines.
MAC address authentication is useful for devices that do not support interactive authentication methods (like printers or IP phones).
It authenticates devices based on theirMAC addresswithout user intervention.
This method is suitable for static, non-user devices that are typically part of the local network.
Use Case:Ensuring that only authorized printers or IP phones connect to the network.
3. 802.1X Authentication:
Scenario:Office users in scenarios demanding high security.
802.1X is aport-based network access control protocolthat authenticates users before allowing network access.
Typically used in wired or wireless LAN environments where high security is required.
It usesEAP (Extensible Authentication Protocol)methods and integrates with RADIUS servers.
Use Case:Corporate LAN environments with stringent security policies.
