Which of the following are the scanning methods used in penetration testing? Each correct answer represents a complete solution. Choose all that apply.
The correct answer is A. Vulnerability B. Port C. Network. Penetration testing employs vulnerability, port, and network scanning as its three recognized scanning method categories. Services enumeration is a sub-activity of these methods, not a standalone category.

Why each option
Penetration testing employs vulnerability, port, and network scanning as its three recognized scanning method categories. Services enumeration is a sub-activity of these methods, not a standalone category.
Vulnerability scanning systematically probes systems for known weaknesses using tools like Nessus or OpenVAS, making it a core pen testing scanning method.
Port scanning discovers open TCP/UDP ports on target hosts using tools like Nmap, revealing potential entry points for exploitation.
Network scanning maps live hosts, topology, and infrastructure across a target network, providing the foundational reconnaissance layer of a penetration test.
Services is not a distinct scanning category - service detection and enumeration are performed as part of port scanning (e.g., Nmap -sV), not a separate method.
