Which Windows command queries the DNS name servers and retrieves information about the target host addresses, name servers, mail exchanges, etc.?

• A. dig command
• B. nslookup
• C. Showmount
• D. VRFY

Answer: (B)

This question is about using a Windows tool to pull DNS information for a target. The Windows command that queries DNS servers and returns the records you need is nslookup. It can reveal host addresses (A/AAAA records), the authoritative name servers (NS records), and mail exchangers (MX records) for a domain. You can perform simple lookups by typing the domain name to get the default A record, or change the record type (for example, set type=MX) to fetch mail server information. You can also specify a particular DNS server to query, which is useful for testing or troubleshooting DNS delegation. Other tools mentioned aren’t focused on DNS queries in the Windows environment: dig is a DNS querying tool more common on Unix-like systems; Showmount deals with NFS exports; VRFY is an SMTP command used to verify addresses, not DNS.
