| You want to configure your DNS server to allow users to type a host name in their browsers to connect to the Web server that is on the same subnet. The host name that all users will type in will be identical regardless of the subnet they are on. You have three subnets in your network, and each Web server on your network contains the same content as all of the Web servers. How should you configure your DNS server?
a. On the primary DNS server, create three A (host) records that map the same host name to IP address of the Web server on each subnet.
b. On the primary DNS server, create one A (host) record that is located on the same sub net as the DNS server. On the secondary DNS servers on the two remaining subnets, edit the zone file for the domain on each DNS server to include an A (host) record for the Web server on each subnet
c. On the primary DNS server, create three A (host) records that map a different host name to the IP address of the Web server on each subnet.
d. On the primary DNS server, create one A (host) record for one Web server and two CNAME (canonical name) records for the remaining two Web servers. | |

| A.
Thought it could be D at first but that would be if you wanted the 3 host names all to point to 1 server. | |

| Answer A is closest but still not a complete answer.
"Netmask ordering" option on a win2k dns server is responsible for what is being asked in the question, in addition to doing what A says. | |

I know nothing about netmask ordering but something about subnet priorization, which is enabled by default on Win2000 DNS client. So, if there is win2000 network, answer A is exactly what we need 
http://www.microsoft.com/technet/tr...rt2/tcpch06.asp
If the resolver receives multiple A resource records from a DNS server, and some have IP addresses from networks to which the computer is directly connected to, the resolver orders those resource records first. This reduces network traffic across subnets by forcing computers to connect to network resources that are closer to them.
It is possible to enable subnet priorization on Win2000 DNS server, then this feature will be available also to non-win2000 clients. | |
