CompTIA Security+ (SY0-501) — Question 196

A security administrator is evaluating three different services: radius, diameter, and Kerberos.
Which of the following is a feature that is UNIQUE to Kerberos?

Answer options

• A. It provides authentication services
• B. It uses tickets to identify authenticated users
• C. It provides single sign-on capability
• D. It uses XML for cross-platform interoperability

Correct answer: B

Explanation

The correct answer is B, as Kerberos uniquely employs tickets for the identification of authenticated users, which is a core aspect of its functioning. While options A and C are features associated with Kerberos, they are not exclusive to it, as other services can also provide authentication and single sign-on. Option D is incorrect because Kerberos does not use XML for interoperability.
