Which of the following statements about Encapsulating Security Payload (ESP) are true? Each correct answer represents a complete solution. Choose two.

ESP (Encapsulating Security Payload) is one of the two primary IPSec protocols, alongside AH (Authentication Header), and it provides confidentiality, data origin authentication, connectionless integrity, and anti-replay protection for IP packets at the network layer.

ESP is a binary network-layer encapsulation protocol that encrypts IP packet payloads - it is not text-based in any form.

TCP port 22 belongs to SSH, not ESP; ESP uses IP protocol number 50, does not rely on a TCP or UDP port, and operates at the network layer rather than the application layer.

ESP can be nested within L2TP to form L2TP/IPSec, a widely deployed VPN configuration in which L2TP provides the tunnel framework and ESP supplies the encryption and authentication, making this a well-documented and supported pairing.
