ICMP Packets
ICMP stands for Internet Control Message Protocol. It is a protocol used for sending error messages and operational information about network conditions. ICMP packets are used by network devices to communicate with each other. Here are some statements regarding ICMP packets:
1. ICMP guarantees datagram delivery - False
ICMP does not guarantee datagram delivery. It is used to report errors and provide information about network problems.
2. ICMP can provide hosts with information about network problems - True
ICMP packets can provide hosts with information about network problems such as unreachable hosts or network congestion.
3. ICMP is encapsulated within IP datagrams - True
ICMP packets are encapsulated within IP datagrams. This means that ICMP packets are sent as part of IP packets.
4. ICMP is encapsulated within UDP datagrams - False
ICMP packets are not encapsulated within UDP datagrams. They are encapsulated within IP datagrams.
Therefore, the correct statements regarding ICMP packets are 2 and 3. ICMP packets can provide hosts with information about network problems, and they are encapsulated within IP datagrams.
