Domain Controllers (Exam 70-642)
When configuring a RODC running Windows 2008 for DNS client updates what is required? (Choose two)
- The DNS zone must be set to allow both secure and non-secure updates.
- There is no option to configure a RODC for DNS client updates.
- Configuration must take place at a writable DNS server.
- The RODC must be promoted to a writable DNS server.
B and C are correct since no configuration DNS or otherwise can be performed at a read-only domain controller.
Answer B may be the choice made at a writable DNS server. Answer D is incorrect as there is no promotion path for RODCs.
Windows Server 2008 DNS servers running on RODCs replicate a full copy of all application directory partitions that DNS uses, including domain and forest.
