CompTIA Security Plus Mock Test Q879

A security administrator has installed a new KDC for the corporate environment. Which of the following authentication protocols is the security administrator planning to implement across the organization?

A. LDAP
B. RADIUS
C. Kerberos
D. XTACACS


Correct Answer: C
Section: Access Control and Identity Management

Explanation:
The fundamental component of a Kerberos solution is the key distribution centre (KDC), which is responsible for verifying the identity of principles and granting and controlling access
within a network environment through the use of secure cryptographic keys and tickets.

Incorrect Answers:
A: The Lightweight Directory Access Protocol (LDAP) is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information
services over an Internet Protocol (IP) network.
B, D: RADIUS and XTACACS do not require a KDC to function.
