Q
Which two types of IPsec can be used to secure communications between two LANs?
AA. Ah tunnel mode
BB. Esp tunnel mode
CC. Both ah tunnel mode and esp tunnel mode
DD. Esp transport mode
Correct Answer:
C. C. Both ah tunnel mode and esp tunnel mode
Explanation:
The AH and ESP tunnel mode IPSec should be used for data transfer purpose, option d is for integrity & confidentiality purpose. Tunnel mode provides security for the entire original IP packet unlike transport mode which is not as secure as it only encrypts the data portion and not the whole packet.
