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
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, andapplications 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.
Incorrect Answers:
B: Security Assertion Markup Language (SAML) is an XML-based, open-standard data format for
exchanging authentication and authorization data between parties, in particular, between an identity
provider and a service provider. SAML is not used for the storage of credential, phone numbers, office
numbers, and address information into one system.
C: Terminal Access Controller Access-Control System (TACACS) is a client/server-oriented environment,
and operates in a manner similar to RADIUS. TACACS is not used for the storage of credential, phone
numbers, office numbers, and address information into one system.
D: Remote Authentication Dial In User Service (RADIUS) is a networking protocol that provides centralized
Authentication, Authorization, and Accounting (AAA) management for users who connect and use a
network service. RADIUS is not used for the storage of credential, phone numbers, office numbers, and
address information into one system.https://msdn.microsoft.com/en-us/library/aa367008(v=vs.85).aspx
