You need to configure the Azure Management Portal to notify you when the SLA performance targets are not met

You manage a web application published to Azure Cloud Services.
Your service level agreement (SLA) requires that you are notified in the event of poor performance from
customer locations in the US, Asia, and Europe.
You need to configure the Azure Management Portal to notify you when the SLA performance targets are
not met.
What should you do?

A.
Create an alert rule to monitor web endpoints.

B.
Create a Notification Hub alert with response time metrics.

C.
Add an endpoint monitor and alert rule to the Notification Hub.

D.
Configure the performance counter on the cloud service.

Explanation:
* An alert rule enables you to monitor an available metric within a supported Azure service. When the
value of a specified metric violates the threshold assigned for a rule, the alert rule becomes active and
registers an alert. When you create an alert rule, you can select options to send an email notification to
the service administrator and co-administrators, or another administrator, when the rule becomes active,
and when an alert condition is resolved.* You can configure cloud service alert rules on:
Web endpoint status metrics
Monitoring metrics from the cloud service host operating system
Performance counters collected from the cloud service guest virtual machine
