What two protocols provide data authentication and integrity for IPsec? (Choose two.)
Explanation: IPsec uses two protocols to provide data integrity and confidentiality, the IP Authentication Header (AH) and the Encapsulating Security Payload (ESP). AH provides integrity and authentication but does not provide encryption. AH can ensure that the original data packet has not been modified during transport but it does not encrypt data to ensure it is viewable only by authorized users. ESP provides confidentiality, integrity, and authentication.
