LPIC-1 Essential System Services and Networking Practice Question

Which TWO tools can be used to query DNS records? (Choose two.)

⚠ Common exam trap

It's easy for candidates to confuse network diagnostic tools (ping, traceroute, ss) with DNS-specific utilities, assuming any tool that tests connectivity can also query DNS records.

Answer choices

Correct answer & explanation

nslookup

A is correct because nslookup is a classic DNS query tool that sends DNS queries to name servers to resolve domain names to IP addresses or vice versa. It directly queries DNS records (A, AAAA, MX, CNAME, etc.) using the DNS protocol (UDP/TCP port 53).
