Which statement best describes a key difference in IPv6 fragmentation support compared to IPv4?
A.
In IPv6, IP fragmentation is no longer needed because all Internet links must have an IP MTU
of 1280 bytes or greater.
B.
In IPv6, PMTUD is no longer performed by the source node of an IP packet.
C.
In IPv6, IP fragmentation is no longer needed since all nodes must perform PMTUD and send
packets equal to or smaller than the minimum discovered path MTU.
D.
In IPv6, PMTUD is no longer performed by any node since the don’t fragment flag is removed
from the IPv6 header.
E.
In IPv6, IP fragmentation is performed only by the source node of a large packet, and not by
any other devices in the data path.
