What is an advantage of using a VPN?

Using a VPN, or Virtual Private Network, is particularly advantageous because it offers secure connections on public networks. When you connect to a public Wi-Fi hotspot, such as those found in cafes or airports, your data can be vulnerable to interception by malicious actors. A VPN encrypts your internet traffic, protecting the information you send and receive from prying eyes. This makes it significantly more difficult for hackers to access sensitive data, such as passwords or personal information, when you are using an unsecured network.

The other choices focus on aspects that do not accurately reflect the primary benefits of a VPN. For example, increasing internet data usage is generally not a goal associated with VPNs and can often lead to slower speeds due to encryption processing. While some free internet access methods may exist, VPNs typically require a subscription for reliable service. Lastly, while a VPN can enhance security, it does not block all incoming network traffic; rather, it secures the data being transmitted to and from the network, allowing for safe communication without necessarily shutting out all other traffic.
