A company has client computers that run Windows 10.
The client computer systems frequently use IPSec tunnels to securely transmit data.
You need to configure the IPSec tunnels to use 256-bit encryption keys.
Which encryption type should you use?

A.
3DES

B.
DES

C.
RSA

D.
AES

Explanation:
IPSec tunnels can be encrypted by 256-bit AES.
L2TP/IPsec allows multiprotocol trafficto be encrypted and then sent over any medium that supports point-topoint datagram delivery, such as IP or Asynchronous Transfer Mode (ATM).
The L2TP message is encrypted with one of the following protocols by using encryption keys generated from
the IKEnegotiation process: Advanced Encryption Standard (AES) 256, AES 192, AES 128, and 3DES
encryption algorithms.
