2. Explain the modifications necessary to DNS for accommodating Read Only Domain Controllers (RODC). How is this different from the way DNS handles ordinary domain controllers? All of the modifications required for accommodating a Read Only Domain Controller are handled through the “adprep / rodcprep step, which modifies the domain schema. A domain-integrated zone on a RODC will not accept Dynamic updates. A file-backed DNS zone on such a RODC would be able to accept dynamic updates, as it has a separate database from the domain database. Server 2008 allows a Domain Controller to not contain a DNS server.
3. Explain Background Zone Loading.
The DNS sever in windows server 2008 makes data retrieval faster by executing background zone loading. In the past, enterprises with zones containing large numbers of records in active directory experienced delays of up to an hour or more when the DNS server services in windows 2003 tried to retrieve the data from active directory on restart.
4. How does background zone loading promotes efficiency in the name resolution? Background zone loading will reduce the time needed to start the DNS server service. The impact will probably only be noticeable for very large zones.
5. Explain how DNS has been modified to add support for IP version 6 (IPv6). How can DNS distinguish between an IP version 4 (IPV4) and IPv6 host in determining which...
