What security benefit does a VPN provide in public Wi-Fi environments?

• A. It increases the Wi-Fi speed
• B. It provides secure access to sensitive information
• C. It blocks all unauthorized users
• D. It disables all other online activities

Answer: (B)

A VPN, or Virtual Private Network, provides a significant security benefit in public Wi-Fi environments by encrypting the data transmitted between the user's device and the VPN server. This encryption helps protect sensitive information from potential interception by malicious actors who might be present on the same public network. As users often connect to untrusted networks in public settings, a VPN ensures that personal data, credentials, and other sensitive information remain confidential and secure during transmission. While aspects like speed or unauthorized access may be mentioned, they do not directly speak to the core security function of a VPN. The enhancement of speed is not a primary purpose of a VPN, nor does it inherently block unauthorized users or disable all other online activities. Security in this context is primarily focused on protecting data integrity and confidentiality, making the provision of secure access to sensitive information the most relevant benefit.
