Which command sends an echo request packet to the target host and then waits for an echo response message?

A.

echo

Answers
A.

echo

B.

access

Answers
B.

access

C.

ping

Answers
C.

ping

D.

connect

Answers
D.

connect

Suggested answer: C

Explanation:

The ping command is specifically designed to test network connectivity and reachability. Here's how it works:

Echo Request: The ping command sends an ICMP (Internet Control Message Protocol) Echo Request packet to a specified destination IP address or hostname.

Echo Response: If the target host is reachable, it will respond with an ICMP Echo Reply packet.

Analysis: The ping command measures the round-trip time (RTT) between the source and destination. It also reports statistics like packet loss and response times.

Why other options are incorrect:

echo: In some command-line environments, the echo command is used to display text on the screen and does not relate to network testing.

access: This is a general term and does not refer to a specific command for sending echo requests.

connect: Some tools use the connect command to establish a TCP connection to a remote host, but it doesn't directly utilize ICMP echo packets like the ping command.
