Your role of Systems Administrator at ABC.com includes the management of the company’s
private cloud. The private cloud is hosted on an internal System Center 2012 infrastructure.
The network infrastructure and private cloud is monitored by System Center 2012 – Operations
Manager (SCOM).

The network contains a number of application servers that run applications used by company
employees.
All application servers in the network have computer accounts in an Active Directory
organizational unit (OU) named AppServersOU.

application servers.
You create a dynamic group named AppServsGroup in SCOM using the following query:

when an error is added to the Application Event logs.
You discover that the alerts are not generated as expected when errors are added to the event
logs on the application servers.
