Given: ABC Company is planning to implement IPSec VPN technology using the Encapsulating Security Payload (ESP) protocol to secure their wireless connections. You are hired as a security consultant to discuss the security strength of this solution.

What statement about this WLAN security implementation is true?

A.
ESP can only use 3DES encryption which causes high latency on half-duplex networks.

B.
Wireless clients should be configured for NAT transparency so encrypted frames can traverse gateways.

C.
ESP uses public key cryptography, which is incompatible with the 802.11 protocol.

D.
The ESP protocol encrypts the entire original frame if implemented in tunnel mode.

E.
When using ESP as a VPN solution, the implementation must incorporate SSH2 tunneling as well.
