PPTP is primarily associated with which security function according to the notes?

• A. Validation of info
• B. Tunneling functionality
• C. Encryption of data
• D. Filtering of packets

Answer: (C)

PPTP is a VPN protocol that forms a tunnel to transport PPP frames over an IP network, and it protects the data inside that tunnel by encryption (via MPPE). Because of this encryption of the payload, the notes emphasize encryption of data as the primary security function associated with PPTP. The tunneling capability is the mechanism that makes the secure channel possible, but the standout protection is the data encryption. Note that PPTP's encryption has known weaknesses and is considered outdated compared to modern options.
