You develop a Web App on a tier D1 app service plan. You notice that page load times increase during periods of peak traffic. You want to implement automatic scaling when CPU load is above 80 percent. Your solution must minimize costs. What should you do first? 

Answer options:

A. Enable autoscaling on the Web App.
B. Switch to the Premium App Service tier plan.
C. Switch to the Standard App Service tier plan.
D. Switch to the Azure App Services consumption plan.

C

Configure the web app to the Standard App Service Tier. The Standard tier supports auto-scaling, and we should minimize the cost. We can then enable autoscaling on the web app, add a scale rule and add a Scale condition.
