PPTP stands for?

• A. Point-to-Point Transport Protocol
• B. Point-to-Point Tunneling Protocol
• C. Private Tunnel Protocol
• D. Public Point Protocol

Answer: (B)

PPTP stands for Point-to-Point Tunneling Protocol. The core idea is that it’s a VPN technology that creates a secure connection by encapsulating PPP frames inside IP packets, using a tunnel (GRE) to carry those frames across an IP network. The emphasis on “Tunneling” is what defines it here—the PPP data is wrapped in another protocol to travel through an intermediary network, rather than being sent directly. The other suggested expansions don’t fit because they replace “Tunneling” with other concepts like mere transport or private/public labeling, which aren’t the standard name for this protocol. Note that PPTP is older and has known security weaknesses, so modern VPNs often use more robust alternatives.
