CompTIA Security Plus Mock Test Q868

Ann has taken over as the new head of the IT department. One of her first assignments was to implement AAA in preparation for the company’s new telecommuting policy. When she takes inventory of the organizations existing network infrastructure, she makes note that it is a mix of several different vendors. Ann knows she needs a method of secure centralized access to the company’s network resources. Which of the following is the BEST service for Ann to implement?


Correct Answer: A
Section: Access Control and Identity Management

The Remote Authentication Dial In User Service (RADIUS) networking protocol offers centralized Authentication, Authorization, and Accounting (AAA) management for users who
make use of a network service.

Incorrect Answers:
B: 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.
C: Security Assertion Markup Language (SAML) is an open-standard data format based on XML.
D: TACACS+ makes use of the authentication, authorization, and accounting (AAA) architecture. However, unlike RADIUS, these separate components of the protocol can be
segregated and handled on separate servers.
