Active Directory Interview Questions and Answers

Mention what is Active Directory?

An active directory is a directory structure used on Micro-soft Windows based servers and computers to store data and information about networks and domains.

What is Domains in Active Directory?

In Windows 2000, a domain defines both an administrative boundary and a security boundary for a collection of objects that are relevant to a specific group of users on a network. A domain is an administrative boundary because administrative privileges do not extend to other domains. It is a security boundary because each domain has a security policy that extends to all security accounts within the domain. Active Directory stores information about objects in one or more domains.

Domains can be organized into parent-child relationships to form a hierarchy. A parent domain is the domain directly superior in the hierarchy to one or more subordinate, or child, domains. A child domain also can be the parent of one or more child domains, as shown below.

Mention which is the default protocol used in directory services?

The default protocol used in directory services is LDAP ( Lightweight Directory Access Protocol).

What is Mixed Mode?

Allows domain controllers running both Windows 2000 and earlier versions of Windows NT to co-exist in the domain. In mixed mode, the domain features from previous versions of Windows NT Server are still enabled, while some Windows 2000 features are disabled. Windows 2000 Server domains are installed in mixed mode by default. In mixed mode the domain may have Windows NT 4.0 backup domain controllers present. Nested groups are not supported in mixed mode.

Explain the term FOREST in AD?
