Analyzing and optimizing technical and business processes

Your company runs a stateless application on a Compute Engine instance. The application is heavily used during normal business hours and lightly used outside those hours. Users report that the application is slow during peak periods. You need to optimize the application's performance. What should you do?

  • A Create a snapshot of the existing disk. Create an instance template from the snapshot. Create an autoscaled managed instance group from the instance template.
  • B Create a snapshot of the existing disk. Create a custom image from the snapshot. Create an autoscaled managed instance group from the custom image.
  • C Create a custom image from the existing disk. Create an instance template from the custom image. Create an autoscaled managed instance group from the instance template.
  • D Create an instance template from the existing disk. Create a custom image from the instance template. Create an autoscaled managed instance group from the custom image.
Explanation

An autoscaled managed instance group adds VM instances as workload demand rises and removes them as demand falls, which suits a stateless application with peak-hour load. Managed instance groups are created from an instance template; creating a custom image from the existing disk allows that template to reproduce the application’s VM configuration consistently.
