1.	In version field of IPv4 header, when machine is using some other version of IPv4 then datagram is __________(a) Discarded(b) Accepted(c) Interpreted(d) Interpreted incorrectlyI had been asked this question in homework.The above asked question is from Network Protocols topic in division Network Protocol of Wireless/Mobile
Answer» Right choice is (a) Discarded The best I can explain: A 4 bit field DEFINES the version of IPv4 PROTOCOL. This field tells the software running in the processing machine that the datagram has the FORMAT of version 4. If the machine is using some other version of IPv4, the datagram is discarded RATHER than interpreted incorrectly.
