Explanation:
The Internet Control Message Protocol (ICMP) is one of the core protocols of the
Internet Protocol Suite.
ICMP differs from transport protocols such as TCP and UDP in that it is not typically used to
exchange data between systems, nor is it regularly employed by end-user network applications
(with the exception of some diagnostic tools like ping and traceroute).
A and E
Answer is A and F
ICMP packets are used by user applications, such as ping, to diagnose network problems.
Common ICMP-based tools, such as ping and traceroute, send probe packets to a host, and measure loss by observing whether or not response packets arrive within some time period.
