VerifiedInfrastructure and System Security

Peter is a Network Administrator for Net World Inc. The company wants to let remote users connect to and access its private network through a dial-up Internet connection. All data will travel across a public network. For security, management wants the data transmitted over the Internet to be encrypted. The company plans to use a Layer 2 Tunneling Protocol (L2TP) connection. Which communication protocol will Peter use to accomplish this task?

Explanation

L2TP is paired with IPsec to secure VPN traffic across a public network. IPsec establishes the protected session and supplies encryption for the L2TP connection; Microsoft documents this configuration as an L2TP/IPsec VPN connection.
