What role does encryption play in a VPN?

• A. It speeds up the connection
• B. It prevents data interception during transmission
• C. It simplifies user authentication
• D. It allows for multiple connections to the VPN server

Answer: (B)

Encryption plays a crucial role in a VPN (Virtual Private Network) by ensuring that the data transmitted over the network is secure and protected from unauthorized access. When data is encrypted, it is transformed into a format that is unreadable to anyone who does not possess the correct decryption key. This means that even if a malicious actor intercepts the data being transmitted over the internet, they would not be able to understand or utilize it without the key to decrypt it. This capability makes encryption essential for maintaining the confidentiality and integrity of data, especially when it travels over public networks where it is susceptible to interception. By preventing data interception during transmission, encryption helps in safeguarding sensitive information such as personal data, passwords, and other confidential communications, allowing users to browse the internet more securely. The other choices, while they might be related aspects of VPN technology, do not accurately capture the fundamental purpose of encryption. For instance, while encryption may have indirect effects on connection speeds or simplify authentication processes, its primary function within a VPN context is to secure data during transmission. Thus, the focus on preventing data interception clearly identifies the critical role of encryption in a VPN.
