What is the primary use of a VPN concentrator as described?

• A. Acts as a gateway for general web traffic
• B. Used for remote access VPNs and allows encrypted tunnel to securely access a corporate network via the internet
• C. Provides hardware load balancing for VPN endpoints
• D. Stores VPN credentials for all users

Answer: (B)

A VPN concentrator is built to terminate and manage many remote-access VPN connections. It acts as the VPN endpoint that remote users connect to over the Internet, establishing encrypted tunnels (such as IPsec or SSL) so that their traffic can securely reach the corporate network. It centralizes authentication, encryption, policy enforcement, and tunnel management for all remote users, making it the primary mechanism for enabling secure, scalable remote access to the internal network. This isn’t about serving general web traffic as a gateway, nor about balancing loads across VPN endpoints as its main function. It isn’t primarily a credential store either, though it may hold keys or certificates as part of its operation. The essential role is to support remote-access VPN connections by aggregating and securing those tunnels into the corporate network.
