You Configured Your Compute Engine Instance Group to Scale Automatically

question 65

Multiple Choice

You configured your Compute Engine instance group to scale automatically according to overall CPU usage. However, your application's response latency increases sharply before the cluster has finished adding up instances. You want to provide a more consistent latency experience for your end users by changing the configuration of the instance group autoscaler. Which two configuration changes should you make? (Choose two.)

• A) Add the label "AUTOSCALE" to the instance group template.
• B) Decrease the cool-down period for instances added to the group.
• C) Increase the target CPU usage for the instance group autoscaler.
• D) Decrease the target CPU usage for the instance group autoscaler.
• E) Remove the health-check for individual VMs in the instance group.
