Answer / guest
Answer: A
Tunnel mode with IP security provides encryption and
authentication of the complete IP package. To accomplish
this, the AH (authentication header) and ESP (encapsulating
security payload) services can be nested. Choices B and C
provide authentication and integrity. TCP services do not
provide encryption and authentication.
