What defines an extranet?

1. A network limited to in-house staff

2. An intranet accessible by authorized external users

3. A public network for general customer access

4. A private network that doesn't connect to the Internet

The correct answer is: An intranet accessible by authorized external users

An extranet is correctly defined as an intranet that is accessible by authorized external users. This means that while the base network is typically used for internal communication and data sharing within an organization, the extranet extends that accessibility to specific users outside the organization, such as partners, vendors, or customers, who require certain information or interaction with the internal systems. This setup allows for secure collaboration and sharing of resources while maintaining a level of control over who can access the information. In contrast, a network limited to in-house staff is strictly an intranet and does not incorporate external users. A public network for general customer access would not contain the security measures typical of an extranet, as it would be open to anyone, undermining the controlled access aspect of an extranet. A private network that doesn't connect to the Internet entirely misses the concept of providing external access, which is fundamental to the definition of an extranet.
