Question 489:
You are working in a start-up company as a DevOps engineer. Due to limited budget, the frontend Auto Scaling group uses Spot Instances in the development environment. Since last Monday, it has become more and more difficult to launch an instance. The ASG reports the error "There is no Spot capacity available that matches your request". Because of this, the frontend page cannot load. You suggested to launch On-Demand Instances however your manager told you to continue using Spot Instances. How would you resolve this problem?
Answer options:
A.Specify several instance types in the Auto Scaling group that are appropriate for the application so that you can get more compute capacity when you have instance type flexibility. B.In the Auto Scaling group instances distribution configurations, modify the On-Demand percentage to be 0% and Spot percentage to be 100%. C.Choose “Lowest price” in the Spot allocation strategy of the Auto Scaling group so that Spot Instances with the lowest price can be launched. D.Create an EC2 Launch Template with a purchased option to specify that only Spot Instances should be launched. Modify the Auto Scaling group to use the new EC2 Launch Template.
