You are planning the design of an encrypted WAN. IP packets will be transferred over encrypted GRE tunnels
between routers B and C. The packet size is limited to a maximum of 1500 bytes inside the WAN between
routers B and C. If endpoint 1 tries to send 1500-byte IP packets to endpoint 2, in what three ways will the
network design handle the fragmentation in three different possible network configurations? (Choose three.)
A. When router B fragments packets after the encryption, router C must reassemble these fragmented
packets.
B. When router B fragments packets before the encryption, router C must reassemble these fragmented
packets.
C. When router B fragments packets after the encryption, the endpoint 2 must reassemble these fragmented
packets.
D. When router B fragments packets before the encryption, endpoint 2 must reassemble these fragmented
packets.
E. When router A fragments packets, router C must reassemble these fragmented packets.
F. When router A fragments packets, endpoint 2 must reassemble these fragmented packets.
