AZ-104 Certification Practice Question #204

Question

You have a Standard Azure App Service plan named Plan1.

You need to ensure that Plan1 will scale automatically when the CPU usage of the web app exceeds 80 percent.

What should you select for Plan1?

Accepted Answer

Azure App Service provides two ways to automatically scale out:
1. **Automatic scaling:** Scales based strictly on incoming HTTP traffic. It does not support custom metrics like CPU or memory.
2. **Autoscale (Rules-based scaling):** Allows defining custom rules based on performance metrics such as CPU usage.
Since the requirement is to scale automatically when the CPU usage exceeds 80%, we must use **Rules Based** scaling in the Scale out method settings.
