A read-only domain controller is also a global catalog server. It hosts a read-only replica of DC=contoso,DC=com, partial replicas for other domains, and local Extensible Storage Engine files. Which statement correctly describes its NTDS.dit and replication role?
DC=contoso,DC=com
NTDS.dit
It's a forest-wide file copied unchanged to every domain controller.
It's the local database for the server's read-only and partial replicas, and the server normally receives ordinary directory and system-volume changes rather than acting as a writable source.
It stores the domain system volume and can originate ordinary directory and policy-file changes for writable domain controllers.
A domain controller restarts after an unplanned power loss. Extensible Storage Engine reports that the database wasn't shut down cleanly. What should an administrator infer first?
The transaction logs should be deleted so the directory service can open the database.
The database is physically corrupt and requires offline repair.
The engine should use its checkpoint and transaction logs for automatic soft recovery before corruption is considered.
Directory replication status is current on two domain controllers, but gpt.ini for one policy has an older version on one server. Which conclusion best fits the evidence?
gpt.ini
The directory component can be current while the file-system component is stale because the two components use separate replication engines.
A current directory replication summary proves that the system volume is also synchronized.
The directory database is inconsistent because Group Policy files replicate inside NTDS.dit.
A client discovers a domain controller and reads a Group Policy container successfully through Lightweight Directory Access Protocol, but its attempt to retrieve the matching template fails. Which evidence should be checked next?
Only the local Extensible Storage Engine checkpoint, because all Group Policy data is in the database.
The forest schema partition, because every template file is represented there.
The system volume and logon shares, Server Message Block access, the template path, and the Distributed File System Replication event log.
An organization plans to enable the Windows Server 2025 optional feature for 32-kilobyte directory database pages. Which preparation is required?
Treat the change as reversible and retain only raw copies of NTDS.dit.
Confirm the required functional levels and capable domain controllers, verify replication health, and account for backup-media compatibility and increased memory use.
Enable the feature on one upgraded domain controller without validating the rest of the forest.
