Which command is used to certify peer name resolution in the context of Active Directory?

The command used to certify peer name resolution in the context of Active Directory is NSLOOKUP. This command is specifically designed to query the Domain Name System (DNS) and to retrieve information about various DNS records, which is crucial for resolving names to IP addresses in a network environment, particularly in Active Directory where services often rely on name resolution.

NSLOOKUP allows users to perform queries against DNS, verifying whether a specific hostname resolves to the correct IP address or identifying issues with name resolution, which is essential for the proper functioning of services like Active Directory since it relies heavily on DNS for locating resources. Peer name resolution ensures that members of the same network can locate each other without the need for direct IP addressing, making NSLOOKUP an invaluable tool in diagnosing and certifying these connections in an Active Directory environment.

Other commands serve different purposes: PING is used to test the reachability of a host on a network, TRACERT determines the path data packets take to reach a specific destination, and NETSTAT displays the current network connections, protocols statistics, and routing tables, but none facilitate the specific task of verifying name resolution like NSLOOKUP does.
