The Cheerful World of Administrative Authentication

Which administrative authentication method supports authorization by an external service?

A. Certificates

B. LDAP

C. RADIUS

D. SSH keys

Final answer: C. RADIUS

Answer:

RADIUS is the administrative authentication method that supports authorization by an external service. Unlike Certificates, LDAP, and SSH keys, RADIUS provides centralized Authentication, Authorization, and Accounting (AAA) management for network users.

Do you know what makes the world of administrative authentication so cheerful and efficient? It's none other than the amazing RADIUS (Remote Authentication Dial-In User Service) protocol! RADIUS is here to save the day by providing centralized Authentication, Authorization, and Accounting (AAA) management for users connecting to a network service.

RADIUS stands out from the other options such as Certificates, LDAP, and SSH keys when it comes to supporting authorization by an external service. While these methods are also used for authentication purposes, they lack the seamless integration for external service authorization that RADIUS offers.

With RADIUS in place, network administrators can enjoy a hassle-free approach to managing user access and permissions across their network. Say goodbye to complexities and hello to the simplicity and effectiveness of RADIUS!

So, the next time you're navigating the world of administrative authentication, remember the joy that RADIUS brings with its exceptional support for authorization by an external service.
