that allows network administrators to manage users’ access to the resources. It identifies all
resources on a network and makes them
accessible to users and applications. Directory service is physically distributed, logically centralized
repository of data that is used to manage a
directory. It provides rules-based access to the data stored within the directory.

remote computers to access Windows-based
programs running on a server.
Answer option A is incorrect. The Simple Mail Transport Protocol (SMTP) service is used for
transferring e-mails between the intranet and the

Internet.
Answer option D is incorrect. The Distributed File System (DFS) service is used to manage logical
volumes distributed across a local or wide
area network. It permits the linking of servers and shares into a simpler, more meaningful name
space. Dfs provides improved load sharing
and data availability.
