You manage the remote access solution for your network. Currently you have two remote access servers, RA1 and RA2, with an additional server, RA3, configured as a RADIUS server. You need to configure RA1 and RA2 to forward authentication requests to RA3. What should you do?

a. On RA1 and RA2, run the Network Policy Server. Create a Remote RADIUS server group, identifying RA3 as the only member.
b. On RA1 and RA2, run the Network Policy Server. Create a network policy and specify RA3 as the MS-RAS Vendon
c. On RA1 and RA2, run the Network Policy Server. Add RA3 as a RADIUS server.
d. On RA1 and RA2, run Routing and Remote Access. Edit the properties of the server and configure it to use RA3 for authentication.

While the customer implements the wireless connectivity system for his network. Usually, there are the following network access servers, with such an additional node, RA3, installed as just a RADIUS server. They have to setup RA1 as well as RA2 to move authorization demands to RA3.

Then he's expected to operate Routing and Wireless Access on RA1 as well as RA2. Change the application property and customize that all together RA3 for authorization.

Thus, the following are the reason that describes the other options are incorrect according to the scenario.
