If you perform a network trace of a ping going through an IPSec/3-DES tunnel, what would be true with respect to the appearance of a tunneled/encrypted packets?
A.
The same key is used, but an index vector is used by IPSec to offset the key, resulting in a unique packet for each transmission.
B.
The encryption key changes for each packet, resulting in a unique packet for each transmission.
C.
The packets will likely be the same except for TTL and the sequence number.
D.
A characteristic of 3-DES ensures that no two packets are alike.
E.
The only way to ensure that packets are unique is to use AH as a header protocol.
