I think it's C.
Router (config) # ip name-server {server address1 thru 6}
The ip name-server command defines which host can provide the name service. To map domain names to IP addresses, you identify the host names; then specify a name server and enable the DNS.

Well, I may or may not regret this, but once again I have a foolish urge

to change my answer.
A & C

I'm going with "C".

I don't see why a domain name is needed by a client to use a DNS server. All that needs to be configured on the client is the ip address of the DNS server.

I agree with Spid. C for me.

I don't believe that a client would or could register with a DNS server other than one in its own domain. Therefore, I think "C" is enough.

I believe that it is assumed that the client is registering with DNS in its own domain. Therefore, I'll go with "C".

And the answer is ....

Correct Answers: A and C

A and C. Correct: Clients accessing a DNS server for name resolution must have configured the domain name and IP address, These two items should be configured on the client computer in its network settings.

B. Incorrect: in-addr.arpa is not required for a client to use the DNS. It is used to configure reverse lookup zones. Reverse lookup zones are not required by Windows 2000. They are used for diagnostic tools such as nslookup.

D. Incorrect: The optional subdomains for the DNS server should be configured at the DNS server. The client does not necessarily need to know the subdomains for which the DNS server is responsible.

Note: It is not necessary for client computers on the Internet to add the DNS server name to their TCP/IP settings. If that were the case, every domain name on the Internet would have to be configured, which would not be realistically possible.

That question is illogical. In order for a client to use a DNS server all they need is an IP of the DNS server. You don't require a domain name to query, Thus a caching only server. They could live without the Domain name.

I choose 'C', because I actually have my DNS servers host by my ISP. All I know is on my TCP/IP setting over at my domain, I just punch in the IPs of the DNS server, and wah-la- the magic show starts .

But the question is "to use DNS". Certainly you can query a DNS server without a domain name, but how does your client register a fully qualified domain name. Using DNS does not imply only querying it, but bieng able to be located through it as well.
