Final answer:
A Site-to-Site VPN is used to connect two networks, such as those of different office locations, allowing shared access to resources across a secure network.
Step-by-step explanation:
The type of VPN that enables connectivity between two networks is known as a Site-to-Site VPN. This VPN type is used to connect the network of one office location to the network at another office location, effectively creating a single, secure network. Large organizations frequently use Site-to-Site VPNs when they have multiple geographically dispersed offices that need to share resources on one private network.
For example, if a company with offices in New York and Los Angeles wants to ensure that file sharing, email, and other services are accessible to all employees regardless of their location, a Site-to-Site VPN could be implemented. This allows the secure sharing of resources without the data being exposed over the public internet.
