The Active Directory database file stores the data and schema information for the Active Directory database on domain controllers in Microsoft…

The Active Directory (AD) database on Windows domain controllers contains critical directory

information, stored in a specific file format.

Why D is correct: The NTDS.DIT file (NT Directory Services Directory Information Tree) is the Active

Directory database file, located in C:\Windows\NTDS\ on domain controllers. It stores all AD objects

(users, groups, computers) and schema data in a hierarchical structure. CNSP identifies NTDS.DIT as

the key file for AD data extraction in security audits.

Why other options are incorrect:

A . NTDS.DAT: Not a valid AD database file; may be a confusion with other system files.

B . NTDS.MDB: Refers to an older Microsoft Access database format, not used for AD.

C . MSAD.MDB: Not a recognized file for AD; likely a misnomer.

Reference: CNSP "Windows Active Directory Security" (Section on Database Files) confirms NTDS.DIT

as the Active Directory database file.
