In which scenario is it most appropriate to use a virtual private network (VPN)?

• A. To connect multiple servers within the same data center
• B. To enable remote access to a corporate network securely
• C. To provide high-speed local area network services
• D. To manage local hardware configurations

Answer: (B)

Using a virtual private network (VPN) is most appropriate for enabling remote access to a corporate network securely. When users are working remotely, whether from home or while traveling, they need a secure way to connect to the corporate network to access files, applications, and other resources safely. A VPN establishes an encrypted channel over the internet, which protects data transmitted between the user's device and the corporate network from potential eavesdroppers. This is essential for maintaining the confidentiality and integrity of sensitive information, especially in situations where unsecured networks are used. In contrast, scenarios involving connecting multiple servers within the same data center, providing high-speed local area network services, or managing local hardware configurations do not require the same level of security that a VPN provides, as these activities typically take place on secure, internal networks, which can use other forms of connectivity without the need for VPN encryption.
