Which type of network allows controlled access to authorized external users?

The correct choice is the extranet, as it is specifically designed to extend part of an organization’s intranet to external users who require access. This controlled environment permits businesses to share certain data and resources with selected external partners, clients, or vendors while maintaining security and privacy.

An extranet typically uses secure protocols, such as a Virtual Private Network (VPN) or authenticated access methods, to ensure that only authorized users can access sensitive information while preventing unauthorized access. This setup is crucial for collaboration with external stakeholders, making it an invaluable tool for businesses operating in a connected world.

In contrast, an intranet is meant for internal use only and does not grant access to external users, while the internet is a public network providing universal access to anyone with a connection. A Local Area Network (LAN) is confined to a limited geographical area and is not designed for external access. Thus, the extranet effectively balances accessibility for authorized users and security for organizational data.
