Which technology allows a user to connect remotely to the corporate network?

The choice of a VPN, or Virtual Private Network, is correct because it provides a secure and encrypted connection over the internet, enabling users to access a corporate network remotely. This technology creates a private tunnel through which data can travel securely, safeguarding sensitive information from unauthorized access.

A VPN is particularly important for remote work scenarios, as it allows employees to connect to their company's resources as if they were on the local network. It also helps ensure that data transmitted between the user’s device and the corporate network remains confidential and protected from potential threats.

In contrast, a firewall primarily acts as a barrier that protects the network from external threats but does not itself facilitate remote access. A proxy server functions by acting as an intermediary for requests from clients seeking resources from other servers, which does not inherently provide remote network connectivity. Lastly, a local area network (LAN) is designed to connect devices in a localized area, such as an office or home, and does not provide the capability for remote connections to a corporate network.
