Explanation:
Point-to-Point Tunneling Protocol (PPTP) is a Microsoft virtual
private network (VPN) protocol. It provides encapsulation, which means it
re-packages the original frame and encrypts it. This allows for secure communication
to take place via an untrusted network, such as the Internet. L2TP is a protocol
that provides just encapsulation, not encapsulation and encryption.
