schema Master
All databases have a schema which is a formal definition (set of rules) which govern the database structure and types of objects and attributes which can be contained in the database. The schema contains a list of all classes and attributes in the forest.
The schema keeps track of:
* Classes
* Class attributes
* Class relationships such as subclasses (Child classes that inherit attributes from the super class) and super classes (Parent classes).
* Object relationships such as what objects are contained by other objects or what objects contain other objects.
There is a class Schema object for each class in the Active Directory database. For each object attribute in the database, there is an attributeSchema object.

Which holds writable copy of AD schema?
Schema Master
What happened schema master fails?
No updates to the Active Directory schema will be possible. Since schema updates are rare (usually done by certain applications and possibly an Administrator adding an attribute to an object), then the malfunction of the server holding the Schema Master role will not pose a critical problem.
Which of the following roles are forest-wide roles?
schema master and domain naming master
Which fsmo role would you house at the Hartford location?
Schema Master and Domain naming master.
What is the .dll used to view the schema master of fsmo roles?
The MMC is used to view the schema master not dll file but you need to register theschmmgmt.dll before you can use the mmctype regsvr32 schmmgmt.dll
A schema is defined as a master database which has the following two parts?

What are the FSMO roles?
FSMO stands for the Flexible single Master Operation, there are 5 types of FSMO Schema Master Domain Naming Master Infrastructure Master Remote ID Master(RID) PDC Emulator Regards Anil Mahapatra
What are FMSO Servers?
Flexible Single Master Operations servers. They are servers that every Active Directory needs that serve a single purpose. Here are the FSMO servers: Schema Master Domain Naming Master Infrastructure Master Relative ID Master PDC Emulator Those are the five FSMO server rolls that get assigned to 1 or more domain controllers in each domain. Schema and Domain Naming Master will have only 1 server per AD Forest.
How many types of Domain controller?
The domain controller is only of one type but it can have different roles Domain Naming master RID master PDC Schema Master Infrastructure master Schema master (forest wide): The Schema Master controls all updates to the Schema within the forest. Domain Naming Master (forest wide): The Domain Naming Master role is responsible for the creation and deletion of domains in the forest. PDC Emulator (domain wide): The PDC emulator role provides backwards compatability for Windows NT backup domain controllers (BDCs), the PDC emulator advertises itself as the primary domain controller for the domain. It also acts as the domain master browser and maintains the latest password for all users within the domain. Infrastructure Master (domain wide): The Infrastructure Manager role is responsible for updating references from objects within its domain with objects in other domains. RID Master (domain wide): The RID Master manages the Security Identifier (SID) for every object within the
What is the difference between transferring a fsmo role and seizing one which one should you not seize why?
Seizing an FSMO can be a destructive process and should only be attempted if the existing server with the FSMO is no longer available.If the domain controller that is the Schema Master FSMO role holder is temporarily unavailable, DO NOT seize the Schema Master role.If you are going to seize the Schema Master, you must permanently disconnect the current Schema Master from the network.If you seize the Schema Master role, the boot drive on the original Schema Master must be completely reformatted and the operating system must be cleanly installed, if you intend to return this computer to the network.NOTE: The Boot Partition contains the system files (\System32). The System Partition is the partition that contains the startup files, NTDetect.com, NTLDR, Boot.ini, and possibly Ntbootdd.sys.The Active Directory Installation Wizard (Dcpromo.exe) assigns all 5 FSMO roles to the first domain controller in the forest root domain. The first domain controller in each new child or tree domain is assigned the three domain-wide roles. Domain controllers continue to own FSMO roles until they are reassigned by using one of the following methods:
What is star flake schema?
