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
Looks like there are some tricks to installing DHCP on an RODC
