Which tunneling protocol is commonly associated with Windows VPNs and is listed as PPTP in the material?

• A. SSTP
• B. L2TP
• C. OpenVPN
• D. PPTP

Answer: (D)

PPTP stands for Point-to-Point Tunneling Protocol, and it’s the tunneling method most closely associated with Windows VPNs. It was designed to be easy to set up with the Windows VPN client and became the default option in many Windows environments, which is why material commonly lists it simply as PPTP. PPTP works by tunneling PPP frames inside a GRE (protocol 47) tunnel and using MPPE for encryption, making configuration straightforward but introducing known security weaknesses. Because of those vulnerabilities, PPTP is considered less secure than alternatives, which is why modern guidance often favors SSTP, L2TP over IPsec, or OpenVPN for strong protection. The key takeaway is that PPTP’s strong association with Windows VPNs is due to its historical integration and ease of use within Windows, which is why it’s the option described in the material.
