CompTIA Network+ (N10-009) — Question 372

A user is unable to reach a website and wants to verify its IP information. Which of the following tools is used to resolve the authoritative server to its FQDN?

Answer options

• A. ipconfig
• B. arp
• C. nslookup
• D. ping

Correct answer: C

Explanation

The correct answer is C, nslookup, as it is specifically designed to query DNS records and retrieve FQDNs from authoritative servers. Options A (ipconfig) and B (arp) do not provide DNS resolution capabilities, while D (ping) is used to test connectivity rather than resolving FQDNs.
