The header length of an IPv6 datagram is ___________
A. 10bytes B. 25bytes C. 30bytes D. 40bytes
Explanation: IPv6 datagram has fixed header length of 40bytes, which results in faster processing of the datagram. There is one fixed header and optional headers which may or may not exist. The fixed header contains the mandatory essential information about the packet while the optional headers contain the optional “not that necessary” information.
