CompTIA Network+ (N10-007) — Question 561

Management is concerned there is excessive traffic on the network. A network technician wants to run a quick port scan to see any systems that have open ports.
Which of the following tools should be used to do this?

Answer options

• A. tcpdump
• B. dig
• C. nmap
• D. netstat

Correct answer: C

Explanation

The correct answer is C, nmap, which is specifically designed for network exploration and security auditing, making it ideal for port scanning. Option A, tcpdump, is primarily used for capturing and analyzing network packets, not for scanning ports. Option B, dig, is a tool for DNS lookup, and option D, netstat, displays network connections and statistics, but does not perform port scans.
