Provide an overview of Microsoft's Point-to-Point Tunneling Protocol (PPTP).

What will be an ideal response?

Microsoft's Point-to-Point Tunneling Protocol (PPTP) is an advanced version of PPP that handles the connection right out of the box. Microsoft places the PPTP endpoints on the client and the server. The server endpoint is a special remote access server program on a Windows server, called Routing and Remote Access Service (RRAS). On the Windows client side, you run Add a VPN connection in Settings in the Control Panel. (With older versions of Windows, you would run the Create a new connection option in the Network and Sharing Center applet.) This creates a virtual NIC that, like any other NIC, does a DHCP query and gets an IP address from the DHCP server on the private network.
