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.
