Explanation:
* Policy-Based Management is helpful in resolving the issues presented in the following scenario:
A company policy prohibits enabling Database Mail or SQL Mail. A policy is created to check the server state of those two features. An administrator compares the server state to the policy. If the server state is out of compliance, the administrator chooses the Configure mode and the policy brings the server state into compliance.
* Events are generated by SQL Server and entered into the Microsoft Windows application log. SQL Server Agent reads the application log and compares events written there to alerts that you have defined.
When SQL Server Agent finds a match, it fires an alert, which is an automated response to an event. In addition to monitoring SQL Server events, SQL Server Agent can also monitor performance conditions and Windows Management Instrumentation (WMI) events.
To define an alert, you specify:
The name of the alert.
The event or performance condition that triggers the alert.
The action that SQL Server Agent takes in response to the event or performance condition.
