Which tool is described as an IP address and port scanner suitable for quick scans?

• A. ICMP timestamp ping
• B. ICMP address mask ping
• C. Angry IP Scanner
• D. TCP Connect / Full Open Scan

Answer: (C)

Quickly discovering which IP addresses are active and which ports are open is the idea here. Angry IP Scanner is built for that purpose: a lightweight, cross‑platform tool that scans a range of IPs and reports which hosts respond and which ports are open. Its speed and simplicity make it ideal for a quick network sweep without the complexity of full-featured scanners. It’s commonly used to get a fast snapshot of a network, especially when you want results fast and with minimal setup.

The ICMP timestamp ping and ICMP address mask ping are just ways to check if a host is reachable; they don’t scan ports. The TCP Connect / Full Open Scan describes a scanning method used by some tools to check ports, but it isn’t naming a specific quick-scanning IP/port tool—Angry IP Scanner is the well-known application that fits the description.
