   A company runs a web application on a managed instance group. They have configured autoscaling based on CPU utilization. Recently, they noticed that during traffic spikes, the autoscaling policy is slow to add instances, leading to performance degradation. They want to improve the responsiveness of autoscaling without significantly increasing costs. What is the best action to take?

   • AUse a larger VM type to handle more traffic per instance.
   • BIncrease the cool-down period for the autoscaling policy.
   • CDisable autoscaling and manually add instances during peak times.
   • DChange the autoscaling metric to be based on request count per instance, which reacts faster to traffic changes.
