Which of the following is considered a RADIUS client?

  1. A Windows 10 computer with a VPN connection

  2. A server installed with the NPS server role

  3. A VPN server

  4. An Azure VM

The correct answer is: A VPN server

A VPN server is considered a RADIUS client because it acts as a mediator between the end-user devices attempting to connect and the RADIUS server, which provides authentication, authorization, and accounting services. When a user attempts to connect to the VPN, the VPN server collects the user's credentials and then forwards them to the RADIUS server for verification. This process enables secure connection methods and helps manage user access effectively. The other options involve different roles and responsibilities in relation to the RADIUS authentication process. A Windows 10 computer with a VPN connection does not serve as a client in the context of RADIUS; instead, it is the end user connecting to the VPN. A server with the NPS (Network Policy Server) role acts as a RADIUS server rather than a client, serving to authenticate requests from RADIUS clients. An Azure VM can run any type of service but does not inherently function as a RADIUS client unless specifically configured to do so in conjunction with networking and access management services.
