Answer Posted / guest
Answer: D
Internet Control Message Protocol - ICMP is a management
protocol and
messaging service provider for IP. Its messages are carried
as IP
datagrams.
ICMP is used in the following events:
Destination Unreachable - If a router cannot send an IP
packet any
further, it uses an ICMP echo to send a message back to the
sender
notifying it that the remote node is unreachable.
Buffer Full - If a routers memory buffer is full ICMP will
send out a
message to the originator.
Hops - Each IP datagram is assigned a path. This consists of
hops. If it
goes through the maximum number of hops, the packet is
discarded and the
discarding router sends an ICMP echo to the host.
Ping - Ping use ICMP echo message to check connectivity.
