Your network contains 10 domain controllers, 10 member servers, and approximately 1,000 client computers. All the servers run Windows 2000 Server, and all the client computers run Windows 2000 Professional. Two of the domain controllers act as DNS servers. Users of client computers use file sharing to grant access to files stored locally. The network has 10 subnets and uses TCP/IP as the only network protocol. You want to configure the network so that all computers can resolve the addresses of all other computers by using DNS. Client computers must be able to register and resolve addresses if a server fails. How should you configure the DNS servers?

Configure one server with a standard primary zone for the domain, and configure at least one server with standard secondary zone

Configure one server with a standard primary zone for the domain, and configure at least one server with an Active Directory integrated primary zone

Configure one server with an Active directory integrated primary zone for the domain, and configure at least one server with a standard secondary zone

Configure at least two servers with Active Directory integrated primary zones for the domain

Configure at least two servers with standard primary zones for the domain
