Your company has a private cloud that is managed by using a System Center 2012 Operations
Manager infrastructure.
The network contains three devices.
The devices are configured as shown in the following table.
You need to ensure that Operations Manager can discover all of the devices.
What should you do?

A.
From the Operations Manager console, create one group and set the group to Dynamic Members.

B.
From the Operations Manager console, create two Run As Accounts.

C.
From the Operations Manager Shell, run the Set-SCOMUserRole cmdlet.

D.
From the Operations Manager Shell, run the Enable-SCOMDiscovery cmdlet.

Explanation:
Each SNMPv3 device would need its own run as account.
As there are no SNMPv3 devices in the list only v1/v2 we need just one run as account per different
community string.
As there are two diffrent community strings used for the 3 devices we need two run as accounts.
