What type of network serves as an extension of an intranet to business partners?

1. Intranet

2. Internet

3. VPN

4. Extranet

The correct answer is: Extranet

The correct answer is the type of network that serves as an extension of an intranet to business partners is an extranet. An extranet enables organizations to provide controlled access to their internal networks and specific information or applications to external parties, such as business partners, suppliers, and customers. This setup supports collaboration and efficient data sharing while maintaining security controls to protect sensitive information. Extranets typically utilize secure connections, often through technologies such as VPNs, to ensure that data exchanged between the organization and external partners remains confidential and protected from unauthorized access. They are designed to enhance communication and workflow outside the organization while still being an integral part of the company’s intranet structure. The other options refer to different networking concepts. An intranet is used exclusively within an organization and is not accessible to outsiders. The internet is a global network that connects millions of private, public, academic, business, and government networks, but it does not define a specific relationship or access level for business partners. A VPN (Virtual Private Network) is a technology that creates a secure connection over the internet, often used to connect to an intranet, but it does not itself serve a distinct purpose as an isolated network for business partners.
