Answer - A - Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables the secure transfer of data from a remote client to a private enterprise server by creating a virtual private network (VPN) across TCP/IP-based data networks.

Key Takeaway: The PPP frame is encrypted with Microsoft Point-to-Point Encryption (MPPE) by using encryption keys generated from the MS-CHAPv2 or EAP-TLS authentication process. VPN clients are forced to use the MS-CHAPv2 or EAP-TLS authentication protocol to encrypt the payload of PPP frames. SSH is a network protocol that allows data to be exchanged using a secure channel between two networked devices. Point-to-Point Protocol, or PPP, is a data link protocol commonly used to establish a direct connection between two networking nodes. Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer Protocol and a cryptographic protocol.
