You plan to deploy serverl.child.contoso.com as a read-only domain controller (RODC).
You run the adprep.exe /rodcprep command on DC3 and receive the following error
message:
You need to identify what prevents you from successfully running Adprep /rodcprep on DC3.
What should you identify?
A.
The domain functional level of child.contoso.com isset to the wrong level.
B.
DC3 cannot connect to the domain naming master on DC1.
C.
The forest functional level is set to the wrong level.
D.
DC3 cannot connect to the infrastructure master onDC2.
Correct:
This problem occurs when the Adprep /rodcprep command tries to contact the infrastructure master for each application partition in the forest. The command does this to set the permissions that are required for Read-Only Domain Controller (RODC) replication. The Adprep /rodcprep command fails if one of the following conditions is true:
The partition or the partitions that are referenced in the error message no longer exist.
The infrastructure master for the referenced partition or partitions has been forcefully demoted or is offline.
