CompTIA Security+ Question E-34

The security manager wants to unify the storage of credential, phone numbers, office numbers, and address information into one system. Which of the following is a system that will support the requirement on its own?

A. LDAP
B. SAML
C. TACACS
D. RADIUS

Answer: A

Explanation:
A ‘directory’ contains information about users. The Lightweight Directory Access Protocol (LDAP) is a directory service protocol that runs on a layer above the TCP/IP stack. It provides a mechanism used to connect to, search, and modify Internet directories. 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. Directory services play an important role in developing intranet and Internet applications by allowing the sharing of information about users, systems, networks, services, and applications throughout the network. As examples, directory services may provide any organized set of records, often with a hierarchical structure, such as a corporate email directory. Similarly, a telephone directory is a list of subscribers with an address and a phone number.
