Your network contains 10 domain controllers that run Windows Server 2008 R2. The
network contains a member server that is configured to collect all of the events that occur on
the domain controllers.
You need to ensure that administrators are notified when a specific event occurs on any of
the domain controllers. You want to achieve this goal by using the minimum amount of
administrative effort.
What should you do?

A.
From Event Viewer on the member server, create a subscription.

B.
From Event Viewer on each domain controller, create a subscription.

C.
From Event Viewer on the member server, run the Create Basic Task Wizard.

D.
From Event Viewer on each domain controller, run the Create Basic Task Wizard.

Explanation:
Since the member server is collecting all domain controller events we just need to run the
Create Basic Task Wizard on the member server, which enables us to send an e-mail when
a specific event is logged. Running the wizard on every domain controller would work, but is
much more work and we need to use the minimum amount of administrative effort.

To Run a Task in Response to a Given Event
1. Start Event Viewer.
2. In the console tree, navigate to the log that contains the event you want to associate with
a task.
3. Right-click the event and select Attach Task to This Event.
4. Perform each step presented by the Create Basic Task Wizard.
In the Action step in the wizard you can decide to send an e-mail.
