CompTIA PenTest+ (PT0-003) — Question 83

Before starting an assessment, a penetration tester needs to scan a Class B IPv4 network for open ports in a short amount of time. Which of the following is the best tool for this task?

Answer options

• A. Burp Suite
• B. masscan
• C. Nmap
• D. hping

Correct answer: B

Explanation

The correct answer is B, masscan, which is designed for high-speed port scanning and can quickly scan large networks, such as a Class B IPv4 network. While Nmap (C) is a powerful tool for network scanning, it is not as fast as masscan when it comes to scanning large networks. Burp Suite (A) is primarily a web application security testing tool, and hping (D) is more suited for crafting packets rather than performing rapid port scans.
