Which Windows tool is commonly used for DNS queries and resolving domain names to IP addresses?

• A. nslookup
• B. dig command
• C. Showmount
• D. SMTP-ENUM

Answer: (A)

This question tests the Windows tool you use to query DNS records and translate domain names into IP addresses. The best choice is nslookup. It’s a command-line utility built into Windows that asks a DNS server for information about a domain, such as its A record that maps the domain to an IPv4 address (and you can also query other record types like AAAA, MX, etc.). You can run it in interactive mode or simply specify a domain to get the result. For example, a basic query like nslookup example.com will return the IP address if an A record exists, and you can change the query type to fetch other records, such as nslookup -type=MX example.com to see mail servers. The other options aren’t Windows DNS query tools. The dig command serves a similar purpose but isn’t included by default in Windows. Showmount is related to NFS shares, not DNS. SMTP-ENUM refers to enumerating SMTP servers, not translating domain names to IPs.
