Which of the following statements about Read-only Domain Controllers is accurate?

The statement that Read-only Domain Controllers (RODCs) do not replicate to standard domain controllers is accurate. RODCs are designed specifically to hold a read-only copy of the Active Directory database. This feature helps enhance security in environments where a domain controller may be deployed in less secure locations, such as branch offices.

Unlike standard domain controllers that host a writable copy of the Active Directory, RODCs can’t make changes to the directory data or replicate those changes back to the domain. This ensures that any potential compromise of an RODC does not affect the integrity of the entire Active Directory infrastructure since it cannot propagate changes.

The other statements do not accurately reflect the functionality and purpose of RODCs. They cannot replicate to other RODCs, as replication in the context of RODCs is only one way: from a writable domain controller to an RODC, not the other way around. RODCs are not utilized to perform updates to Active Directory; instead, they provide service by responding to queries without allowing modifications to the directory. Lastly, while RODCs provide essential directory services, they do so in a limited manner, as they cannot provide full directory services like a writable domain controller can.
