A.
In place encryption

B.
Tunneling mode encryption

Explanation:

: IKE uses “Tunneling mode” encryption, which works by encapsulating the entire packet, and
then adding its own encryption protocol header to the encrypted packet. A drawback of using
tunneling mode encryption is that the packet size has been increased. This increase in the packet
size degrades network performance, however, the security of the packet is increased. See Page
