QUESTION 111
Your network contains four servers named Server1, Server2, Server3, and Server4 that run Windows Server 2008 R2.
The servers have the Network Policy Server (NPS) role service installed.
You configure a Remote RADIUS Server Group named Group1.
Group 1 contains Server2, Server3, and Server4.
You need to configure load balancing for the members of Group1 to meet the following requirements:
– Server1 must send 25 percent of all authentication requests to Server3.
– Server1 must send 75 percent of all authentication requests to Server2.
– Server1 must only send authentication requests to Server4 if Server2 and Server3 are unavailable.
What should you do from the Network Policy Server console?

A.    For Server2, set the weight to 75 and the priority to 75,
For Server3, set the weight to 25 and the priority to 25.
For Server4, set the weight to 100 and the priority to 200.
B.    For Server2, set the weight to 75 and the priority to 1.
For Server3, set the weight to 25 and the priority to 1.
For Server4, set the weight to 100 and the priority to 100.
C.    For Server2, set the weight to 1 and the priority to 75.
For Server3, set the weight to 1 and the priority to 25.
For Server4, set the weight to 100 and the priority to 1.
D.    For Server2, set the weight to 75 and the priority to 25.
For Server3, set the weight to 25 and the priority to 75.
For Server4, set the weight to 100 and the priority to 1.

Answer: B
Explanation:
RADIUS server priority and weight
During the NPS proxy configuration process, you can create remote RADIUS server groups and then add RADIUS servers to each group. To configure load balancing, you must have more than one RADIUS server per remote RADIUS server group. While adding group members, or after creating a RADIUS server as a group member, you can access the Add RADIUS server dialog box to configure the following items on the Load Balancing tab:
Priority: Priority specifies the order of importance of the RADIUS server to the NPS proxy server. Priority level must be assigned a value that is an integer, such as 1, 2, or 3.
The lower the number, the higher priority the NPS proxy gives to the RADIUS server.
For example, if the RADIUS server is assigned the highest priority of 1, the NPS proxy sends connection requests to the RADIUS server first; if servers with priority 1 are not available, NPS then sends connection requests to RADIUS servers with priority 2, and so on.
You can assign the same priority to multiple RADIUS servers, and then use the Weight setting to load balance between them.
Weight: NPS uses this Weight setting to determine how many connection requests to send to each group member when the group members have the same priority level. Weight setting must be assigned a value between 1 and 100, and the value represents a percentage of 100 percent. For example, if the remote RADIUS server group contains two members that both have a priority level of 1 and a weight rating of 50, the NPS proxy forwards 50 percent of the connection requests to each RADIUS server.
Advanced settings: These failover settings provide a way for NPS to determine whether the remote RADIUS server is unavailable. If NPS determines that a RADIUS server is unavailable, it can start sending connection requests to other group members. With these settings you can configure the number of seconds that the NPS proxy waits for a response from the RADIUS server before it considers the request dropped; the maximum number of dropped requests before the NPS proxy identifies the RADIUS server as unavailable; and the number of seconds that can elapse between requests before the NPS proxy identifies the RADIUS server as unavailable.
