Q. What is Active Directory?

A Windows-based directory service. Active Directory stores information about objects on a network and makes this information usable to users and network administrators. Active Directory gives network users access to permitted resources anywhere on the network using a single logon process. It provides net-work administrators with an intuitive, hierarchical view of the network and a single point of administration for all network objects.

Q. What is domain?

A collection of computer, user, and group objects defined by the administrator. These objects share a common

directory database, security policies, and security relationships with other domains.

Q. What is forest?

One or more Active Directory domains that share the same class and attribute definitions (schema), site, and replication information (configuration), and forest-wide search capabilities (global catalog). Domains in the same forest are linked with two-way, transitive trust relationships.

Q. What is organizational unit (OU)?

An Active Directory container object used within domains. An OU is a logical container into which users, groups, computers, and other OUs are placed. It can contain objects only from its parent domain. An OU is the smallest scope to which a GPO can be linked, or over which administrative authority can be delegated.

Q. What is site?

One or more well-connected (highly reliable and fast) TCP/IP subnets. A site allows administrators to configure

Active Directory access and replication topology to take advantage of the physical network.

Q. How is a directory service different from a directory?

A directory service differs from a directory in that it is both the source of the information and the mechanism that

makes the information available to the users.

Q. How is Active Directory scalable?

Active Directory enables you to scale the directory to meet business and network requirements through the configuration of domains and trees, and the placement of domain controllers. Active Directory allows millions of objects per domain and uses indexing technology and advanced replication techniques to speed performance.

Q. What is multimaster replication?

Multimaster replication is a replication model in which any domain controller accepts and replicates directory changes to any other domain controller. Because multiple domain controllers are employed, replication continues, even if any single domain controller stops working.

Q. Name the Active Directory components used to represent an organization’s logical structure.?

The Active Directory components used to represent an organization’s logical structure are domains, organizational

units (OUs), trees, and forests.

Q. Name the physical components of Active Directory.

The physical components of Active Directory are sites and domain controllers.

Q. What is the function of the global catalog?

The global catalog has two main functions: (1) it enables a user to log on to a network by providing universal group membership information to a domain controller when a logon process is initiated, and (2) it enables finding directory information regardless of which domain in the forest actually contains the data.
