What does the AD DS?

Enables you to create organizational divisions called domains.

What is a domain?

A domain is a logical container of network components, hosted by at least one server.

What for structure does a AD DS domain have?

Hierarchical structure that takes the form of a tree, much like a file system.

The domain consist of objects, each of which represents a logical or physical resource objects come in two basic classes.

  • Container object: Can have other objects subordinate to it
  • Leaf objects: Cannot have subordinate objects

The container objects essentially form the branches of the tree, with the leaf objects growing on the branches.

What does leaf object represent?

  • Users
  • Computers
  • Groups
  • Applications
  • and other resources on the network

Every object consist of attributes, what is the attribute of a container object?

A container object has, as one of its attributes a list of all the other objects it contains.

What is the attribute of a Leaf object?

That contain information about the specific resource the object represents.

What is GUID and where stands it for?

GUID is an attribute that is automatically created that the domain controller assigns to each object when it creates it. It stands for Globally unique identifier

Object's place in the directory tree are all defined in the (fill in) ........ .....?

Directory schema

The hierarchical structure used in AD DS are based on a standard which standard is it and tell more information about it.

The standard is called X.500 which was developed by the International Telecommunications Union (ITU) in the late 1980s

Domains are not security boundaries why?

Users in one domain cannot access the resources of another domain unless they receive explicit permissions to do so, that means that domains are not completely isolated from one another. If you perform tasks in one domain that affect all other domains in the forest.

How can we isolate domains one from another?

To completely isolate one domain from another, you must create them in different forests. The forest functions as the security boundry, not the domain.

What is an OU and where stands it for?

OU is a container object that functions in a subordinate capacity to a domain, something like a subdomain, but without the complete seperation of security policies.
