CompTIA Network+ (N10-007) — Question 469

While troubleshooting a connectivity issue, a network technician successfully pinged the loopback address and external DNS server but was unable to ping the website's URL. Which of the following tools should the technician use to determine where the network issue is located?

Answer options

• A. Nmap
• B. netstat
• C. nslookup
• D. ipconfig
• E. tracert

Correct answer: C

Explanation

The correct choice is nslookup, as it allows the technician to query the DNS to verify domain name resolution issues. The other options do not directly address DNS queries; Nmap is for network discovery, netstat shows active connections, ipconfig displays network configuration, and tracert traces the route to a destination but does not resolve DNS names.
