Which System Center 2012 roles should you recommend?

Your network contains 20 servers that run Windows Server 2012.
The servers have the Hyper-V server role installed.
You plan to deploy a management solution.
You need to recommend which Microsoft System Center 2012 roles must be deployed to meet the following requirements:
An administrator must be notified when an incident occurs, such as a serious error in the event log, on a Hyper-V host, or on a virtual machine.
An administrator must be able to assign an incident to a specific administrator for resolution.
An incident that remains unresolved for more than 10 hours must be escalated automatically to another administrator.
Administrators must be able to generate reports that contain the details of incidents and escalations.
Which System Center 2012 roles should you recommend? More than one answer choice may achieve the goal. Select the BEST answer.

A.
Operations Manager and Service Manager

B.
Service Manager and Virtual Machine Manager (VMM)

C.
Configuration Manager and Service Manager

D.
Operations Manager and Orchestrator

Explanation:
Operations Manager – This is a MONITORING tool, it monitors things, but it ALSO can create ALERTS. Operations Manager Alerts are basically Events that are
triggered by a predefined action (for example, you can create an Alert that is triggered whenever App1 crashes).
SCOM Alerts can then be exported from Operations Manager by a “connector” which will then import them into a different SC2012 feature such as:
Service Manager – When an Alert is imported into Service Manager, it sits there as an “Event” which can then be MANAGED by an Administrator, or delegated, or
Administrated etc.
OR
Orchestrator – When an Alert is imported into Orchestrator, an Orchestrator Runbook can be employed to automate a task that is triggered by the Alert. For
example, we can configure Orchestrator to automatically restart App1 whenever a specific App1 crash Alert is sent to it.
Here, criteria 1 and 4 are met by Operations Manager, while criteria 2 and 3 are met by Service Manager.
GOLDEN RULE for answering these types of question:
1. Orchestrator – AUTOMATES Things!
2. Service Manager – WORKFLOWS, Client-Portals, Allows event to be managed by Administrators!
3. Operations Manager – MONITORS, Creates Alerts, Creates Reports!
