Question

What is a computer network tool used to test whether a particular host is reachable across an IP network, sends ICMP "echo request" packets to the target host, and estimates the round trip time and records any packet loss?

A) Router
B) Modem
C) Ping
D) Trace Route

Answer 1

The Ping utility is a network diagnostic tool for testing connectivity, measuring round trip time, and recording packet loss between hosts.

Step-by-step explanation:

The computer network tool used to test whether a particular host is reachable across an IP network, which sends ICMP "echo request" packets to the target host, estimates the round trip time, and records any packet loss, is known as Ping. The correct answer is C) Ping. When you use the Ping command, your system sends out a series of packets to the target host, and then the host is supposed to reply with "echo response" packets. The Ping utility measures the time it takes for the packets to go from the originating host to the target and back again, which is the round-trip time. It also checks for any packets that are lost along the way.
