Which command best identifies DNS information for a domain according to the material?

• A. PING
• B. TRACERT
• C. IPCONFIG
• D. NSLOOKUP

Answer: (D)

When you want to uncover DNS data for a domain, you need a tool that queries DNS servers directly. NSLOOKUP is designed for this purpose: it lets you request specific DNS record types (such as A, AAAA, MX, NS, CNAME, etc.), choose which DNS server to query, and see the exact responses returned by the DNS system. This provides clear insight into how a domain is resolved and which servers are authoritative for it. Other commands aren’t focused on exposing DNS records. PING checks reachability and will perform a DNS lookup behind the scenes to resolve a domain to an IP, but it doesn’t show the DNS records themselves. TRACERT reveals the network path to a host, not the DNS data. IPCONFIG displays your own device’s network configuration (including which DNS servers you use) and not the DNS information for a specific domain. Common usage with NSLOOKUP includes querying the domain to get its A record, or requesting other record types like MX or NS to see mail servers or authoritative name servers. You can also specify a particular DNS server to test how it resolves the domain.
