Windows Active Directory (AD) Interview Questions & Answers

Article Index

1) What is Active Directory ?

Active directory is a hierarchical structure that stores information about objects on the network. Active Directory provides the methods for storing directory data and making this data available to network users and administrators.

2) Active Directory Default Storage ?

Active Directory Data base folder: - D:\WINDOWS\NTDS

Store active Directory log: - D:\WINDOWS\NTDS

SYSVOL By default Location: - D:\WINDOWS\SYSVOL

What is SYSVOL Folder ?

SYSVOL:-The SYSVOL folder stores the server copy of domain public files. The contents of the SYSVOL folder are replicated to all domain controllers in the domain.

It's must be located on an NTFS Volume

3) What is Domain ?

In Active Directory, 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. In Domain Name System (DNS), a domain is any tree or sub tree within the DNS namespace. Although the names for DNS domains often correspond to Active Directory domains, DNS domains should not be confused with Active Directory domains.

4) What is Domain Controller ?

In an Active Directory forest, a server that contains a writable copy of the Active Directory database participates in Active Directory replication, and controls access to network resources. Administrators can manage user accounts, network access, shared resources, site topology, and other directory objects from any domain controller in the forest. See also Active Directory; authentication; directory; forest.

5) What is Domain Services ?

Active Directory provides the means to manage the identities and relationships that make up your organization's network. Integrated with Windows Server 2008, Active Directory gives you out-of-the-box functionality needed to centrally configure and administer system, user, and application settings. Active Directory Domain Services (AD DS) stores directory data and manages communication between users and domains, including user logon processes, authentication, and directory searches.

6) What is Global Catalog (GC) ?

A domain controller that contains a partial replica of every domain in Active Directory. A global catalog holds a replica of every object in Active Directory, but with a limited number of each object’s attributes. The global catalog stores those attributes most frequently used in search operations (such as a user’s first and last names) and those attributes required to locate a full replica of the object. The Active Directory replication system builds the global catalog automatically. The attributes replicated into the global catalog include a base set defined by Microsoft. Administrators can specify additional properties to meet the needs of their installation.

7) What is Forest ?

A collection of one or more Active Directory domains that share a common schema, configuration, and global catalog.

8) What is tree ?

A tree in Active Directory is just an extension of the idea of a directory tree. It’s a hierarchy of objects and containers that demonstrates how objects are connected, or the path from one object to another. Endpoints on the tree are usually objects.
