What are the two modes of IPSec operation?
- A.
VPN And Network
- B.
Network And Packet
- C.
Secure And Insecure
- D.
Tunnel And Transport
Correct Answer
D. Tunnel And TransportExplanation
IPSec (Internet Protocol Security) operates in two modes: Tunnel mode and Transport mode. Tunnel mode encapsulates the entire IP packet within a new IP packet, adding an extra layer of security. It is commonly used for site-to-site VPN connections. Transport mode, on the other hand, only encrypts the data portion of the IP packet, leaving the original IP header intact. It is typically used for host-to-host or end-to-end communication within a network. Therefore, the correct answer is "Tunnel And Transport".Rate this question:
