Your network contains an Active Directory forest named contoso.com. The functional level of the forest is Windows Server 2008 R2.
The DNS zone for contoso.com is Active Directory-integrated.
You deploy a read-only domain controller (RODC) named R0DC1. You install the DNS Server server role on R0DC1.
You discover that R0DC1 does not have any DNS application directory partitions.
You need to ensure that R0DC1 has a copy of the DNS application directory partition of contoso.com.
What should you do? (Each correct answer presents a complete solution. Choose two.)
A. From DNS Manager, right-click RODC1 and click Create Default Application Directory Partitions.
B. Run ntdsutil.exe. From the Partition Management context, run the create nc command.
C. Run dnscmd.exe and specify the /createbuiltindirectorypartitions parameter.
D. Run ntdsutil.exe. From the Partition Management context, run the add nc replica command.
E. Run dnscmd.exe and specify the /enlistdirectorypartition parameter.
