Name the active directory NC's and replication issues for each NC?
*Schema NC, *Configuration NC, * Domain NC Schema NC This NC is replicated to every other domain controller in the forest. It contains information about the Active Directory schema, which in turn defines the different object classes and attributes within Active Directory. Configuration NC Also replicated to every other DC in the forest, this NC contains forest-wide configuration information pertaining to the physical layout of Active Directory, as well as information about display specifiers and forest-wide Active Directory quotas. Domain NC This NC is replicated to every other DC within a single Active Directory domain. This is the NC that contains the most commonly-accessed Active Directory data: the actual users, groups, computers, and other objects that reside within a particular Active Directory domain
What is directory schema?
The Active Directory schema defines the kinds of objects, the types of information about those objects, and the default security configuration for those objects that can be stored in Active Directory. The Active Directory schema contains the formal definitions of all objects, such as users, computers, and printers that are stored in Active Directory. On domain controllers running either Windows 2000 or Windows Server 2003, there is only one schema for an entire forest. This way, all objects that are created in Active Directory conform to the same rules. The schema has two types of definitions: object classes and attributes. Object classes such as user, computer, and printer describe the possible directory objects that you can create. Each object class is a collection of attributes. Attributes are defined separately from object classes. Each attribute is defined only once and can be used in multiple object classes. For example, the Description attribute is used in many object classes, but is defined only once in the schema to ensure consistency.

What object is created when an object is deleted within active directory?
Tombstone
What is lingering objects in Active Directory?
lingering object

Which object classes are created when Active Directory is installed?
object classes and attributes
What contains the rules and definitions that are used for creating and modifiying objects classes and attributes within active directory?
The rules and definitions for creating and modifying object classes and attributes within Active Directory are contained in the Active Directory Schema. The schema defines the types of objects (such as users, groups, and computers) and their attributes, as well as the relationships between them. It can be modified using tools like Active Directory Schema snap-in or Windows PowerShell, allowing administrators to customize the directory according to organizational needs. Changes to the schema are critical as they affect how data is stored and accessed within Active Directory.
Each instance of a class in Active Directory is called?
Object
Which is a physical object domain controller or forest in active directory?
Domain controller is the physical object.
Schemes of defining the logical structure of a directory?
The logical structure of active directory include forest, domains, tree, OUs and global catalogs.Domain : a group of computer and other resources that are part of a windows server2003 network and share a common directory database.Global catalog : Global catalog used to catch information about all object in a forest , the global catalog enables users and applications to find object in an active directory domain tree if the user or application knows one or more attributes of the target object.Tree : Tree as is collection of Active directory Domain, that means the trust relationship can be used by all other domain in the forest as a means to access the domain.Organization Unit - Organization Unit is a Active directory container into which object can be grouped for per mission management.Forest : Active directory forest as due to represents the external boundary of the directory service.These are two types of active directory forest :-I) Single Forest2) Multiple forest
Uniquely identifies an object with in an active directory domain but will change if an object is moved from one domain to anther?
It is the Relative Identifiers (RID) & Security Identifiers (SID) that uniquely identifies an object throughout the Active Directory Domain. On page 85
