In Phase 2 Scanning, which tool is listed for extracting information such as IP addresses?

• A. Vulnerability Scanner
• B. Port Scanner
• C. Packet Sniffer
• D. Firewall

Answer: (B)

In Phase 2 Scanning, the goal is to identify live hosts and map out what’s available on the network by discovering IP addresses and open ports. A port scanner is built for this purpose: it probes a range of IP addresses and reports which hosts respond and which ports are open. That process directly yields the IP addresses of devices on the network and indicates where services are listening, which is exactly what you need to plan the next steps of assessment. Vulnerability scanners focus on finding weaknesses on known hosts and services after you’ve identified targets. Packet sniffers passively observe traffic and can reveal IP addresses seen on the network, but they’re not the primary tool used to enumerate hosts during the scanning phase. Firewalls are defensive controls that filter traffic and don’t help you extract a list of target IPs.
