Q: What would happen to the data if the checksum for a packet delivered at the Internet Protocol (IP) level is not computed?
- The data will be sent back to the sending node with an error.
- It will be sent, but may be out of order.
- The data will be resent
- The data will be discarded
Explanation: It is possible to identify faults in the transfer of data by using checksums. If the checksum validation is unsuccessful, it might be an indication that the packet is incorrect. These kinds of situations result in the packet being dropped, and the transport layer protocol (such as TCP) is the one that is responsible for managing retransmissions if they are required.
