How should you configure Group1?

Your network contains four Network Policy Server (NPS) servers named Server1, Server2,
Servers, and Server4.
Server1 is configured as a RADIUS proxy that forwards connection requests to a remote
RADIUS server group named Group1.
You need to ensure that Server2 and Server3 receive connection requests. Server4 must
only receive connection requests if both Server2 and Server3 are unavailable.
How should you configure Group1?

A.
Change the Weight of Server4 to 10.

B.
Change the Weight of Server2 and Server3 to 10.

C.
Change the Priority of Server2 and Server3 to 10.

D.
Change the Priority of Server4 to 10.

Explanation:
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 settingsprovide 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.
The default priority is 1 and can be changed from 1 to 65535. So changing server 2 and 3 to
priority 10 is not the way to go.
