    I've only played with RODCs a few times in my lab.  The places I support are highly secure so we won't deploy them so these answers are not from my experience in production
    For the DNS -- yes
    Read-only DNS
    You can install the DNS Server service on an RODC. An RODC is able to replicate all application directory partitions that DNS uses, including ForestDNSZones and DomainDNSZones. If the DNS server is installed on an RODC, clients can query it for name resolution as they query any other DNS server.

    However, the DNS server on an RODC is read-only and therefore does not support client updates directly. For more information about how DNS client updates are processed by a DNS server on an RODC
