Installing Active Directory creates the database and database log MCITP certification exams files. The Active Directory database is the directory for the new domain.you can specify a different location when installing Active Directory using the Active Directory Installation Wizard. For best performance and fault tolerance, it's recommended that you place the database and the log file on separate hard disks that are NTFS file system (NTFS) drives, although NTFS is not required. It's also recommended that you have 1 gigabyte (GB) of space to install Active Directory, although the Active Directory Installation Wizard requires only a minimum of 200 megabytes (MB) of disk space for the Active Directory database and 50 MB for the log files.
The directory database is stored in a file named Ntds.dit, which contains all of the information stored in the Active Directory data store. The directory database is an Extensible Storage Engine (ESE) database that contains the schema, global catalog, and objects stored on a domain controller. When Active Directory is installed, Active Directory services ...
... are started from the new copy of the file, and if there are other domain controllers present, the replication process updates the file to the other domain controllers.
Use short, distinct, meaningful names. Use domain names that are easy to use and are representative of your organization's identity.
Use names that have been reviewed internationally. Review domain names to ensure that they are not derogatory or offensive in other languages.
Use names that will remain static. Use generic names rather than specific ones. For example, Microsoft MCITP benefits might use hq.corp.microsoft.com for its Redmond headquarters domain rather than redmond.corp.microsoft.com to avoid the need for change if the headquarters is moved.
Use the International Organization for Standardization (ISO) standards for names that include countries and U.S. states. The ISO defines two-letter country codes and U.S. state codes, as presented in ISO 3166.
Base the internal DNS name on the Internet DNS name. If you use an internal DNS name that is related to the Internet DNS name, it will be easier for users to understand the navigational structure. Consider using the Internet DNS name as a suffix for Active Directory domain names.

Be sure to register and receive verification for domain names before creating your Active Directory domain namespace to avoid having to change domain names. Changing a domain name can take free Microsoft practice questions time and waste resources.
