a) Port scan
b) Vulnerability scan
c) Ping scan
d) Stealth scan

Answer 1

A Ping scan is used to check if a remote host is active by sending it ICMP echo requests. The correct answer is c) Ping scan, which is a crucial technique for network administrators and in network security.

Step-by-step explanation:

A Ping scan demonstrates whether a remote host is active by sending ICMP echo request packets to that host. The correct answer to the question is c) Ping scan. A Ping scan, also known as an ICMP (Internet Control Message Protocol) echo scan, is a basic network scanning technique used to determine if a target host is reachable across an IP network.

It is commonly used to check network connections and troubleshoot connectivity issues. The process involves sending a series of ICMP echo requests, or pings, to a target and waiting for ICMP echo replies. This type of scan is fundamental for network administrators when mapping out networked devices or when performing initial stages of a network security assessment.
