What is the primary use of a VPN?

To enhance wireless signal strength
To support secured communications over an untrusted network
To improve internet browsing speed
To increase bandwidth availability

The correct answer is: To support secured communications over an untrusted network

The primary use of a VPN (Virtual Private Network) is to support secured communications over an untrusted network. A VPN creates a secure, encrypted tunnel through which your data travels, protecting it from potential eavesdroppers and hackers, especially when using public networks like Wi-Fi in coffee shops or airports. This encryption ensures that sensitive information, such as passwords or personal data, is not exposed to anyone who might intercept the communication. In contrast, enhancing wireless signal strength pertains to improving the quality of the Wi-Fi connection itself, which is not a function of a VPN. Improving internet browsing speed and increasing bandwidth availability are also unrelated to the core purpose of a VPN; these aspects would be influenced by your internet service provider or network hardware rather than the use of a VPN for secure communication.
