Answer:
The correct answer to the following question will be Option B (VPN concentrator).
Step-by-step explanation:
- Virtual Private Network (VPN) is a virtual, limited-use network generated using protocol encryption and tunneling over physical, public network connections.
- A dedicated tool for managing VPN connections built over an untrusted network, such as the Internet, is called a VPN concentrator.
- It's a type of networking system that ensures secure VPN connections are established and messages are transmitted between VPN nodes.
Therefore, Option B is the right answer.
