CompTIA Network+ (N10-008) — Question 513

A user notifies a network administrator about losing access to a remote file server. The network administrator is able to ping the server and verifies the current firewall rules do not block access to the network fileshare. Which of the following tools would help identify which ports are open on the remote file server?

Answer options

• A. dig
• B. nmap
• C. tracert
• D. nslookup

Correct answer: B

Explanation

The correct answer is B, nmap, as it is specifically designed to scan and identify open ports on a server. The other options, such as dig and nslookup, are used for DNS queries, while tracert is used to trace the route packets take to a destination but does not provide information about open ports.
