How does Encapsulating Security Payload (ESP) in transport mode affect the Internet Protocol (IP)?
Correct Answer: B
Encapsulating Security Payload (ESP) in transport mode affects the Internet Protocol (IP) by encrypting and optionally authenticating the IP payload, but not the IP header. ESP is a protocol that provides confidentiality, integrity, and authentication for data transmitted over a network. ESP can operate in two modes: transport mode and tunnel mode. In transport mode, ESP only protects the data or payload of the IP packet, while leaving the IP header intact and visible. This mode is suitable for end-to-end communication between two hosts. In tunnel mode, ESP protects the entire IP packet, including the header and the payload, by encapsulating it within another IP packet. This mode is suitable for gateway-to-gateway or host-to-gateway communication
