Plan1 is a Standard App Service plan. To have Plan1 automatically scale when the web app’s CPU usage exceeds 80%, which Scale out method setting should you choose?

To automatically scale based on CPU usage, you must use the "Rules Based" scale out method. This option allows you to define specific metrics (like CPU percentage) and thresholds that trigger scaling actions (in or out). "Automatic" scaling is a simpler, less customizable option that scales based on a pre-defined range of instances without specific metric rules. "Premium P1" and "Standard S1" refer to App Service plan tiers (scaling up), not methods for automatic scaling based on metrics. "Manual" scaling requires you to adjust the instance count yourself, which does not meet the requirement for automatic scaling.
