Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) — Question 53

What does an attacker use to determine which network ports are listening on a potential target device?

Answer options

• A. man-in-the-middle
• B. port scanning
• C. SQL injection
• D. ping sweep

Correct answer: B

Explanation

Port scanning is the correct answer because it specifically involves checking which ports on a device are open and listening for connections. The other options do not pertain to identifying open ports: man-in-the-middle refers to a type of eavesdropping attack, SQL injection is a database attack technique, and ping sweep is used to determine active devices on a network, not to assess open ports.
