Your company has a private cloud that is managed by using a System Center 2012 infrastructure.

You deploy an application virtualization solution.

You deploy a server named RDServer1, and then you install the Remote Desktop Services server role.

RDServer1 is monitored by using Operations Manager.

You deploy a virtualized application named VirtualApp1 to RDServer1.

You need to set the state of RDServer1 to critical if CPU utilization by VirtualApp1 exceeds 70 percent for two minutes.

What should you create?

A.
a service level objective (SLO)

B.
an event subscription

C.
an application profile

D.
a monitor

E.
a rule

Explanation:
You can configure a service level objective (SLO) to define the availability and performance goals for an application. In the following procedure, you create a new service level (LOB Application 1) against a distributed application, define a Monitor SLO that is based on availability (99.9% up-time), and define a Collection Rule SLO that is based on a performance rule (80% average processor time).
