Question
Which of the following represents the correct scenario where an Auto Scaling group's (ASG) predictive scaling can be effectively used to maintain the required number of AWS resources?Question 21Answera.To manage a fixed number of resources in the Auto Scaling groupb.To manage a workload that exhibits recurring load patterns that are specific to the day of the week or the time of dayc.To help configure a scaling policy to keep the average aggregate CPU utilization of your Auto Scaling group at 40 percentd.To help configure a CloudWatch Amazon Simple Queue Service (Amazon SQS) metric like Approximate Number of Messages Visible for scaling the group based on the value of the metric
Solution
The correct scenario where an Auto Scaling group's (ASG) predictive scaling can be effectively used to maintain the required number of AWS resources is:
b. To manage a workload that exhibits recurring load patterns that are specific to the day of the week or the time of day
Predictive scaling works best when there are predictable and recurring load patterns. It uses machine learning algorithms to predict future traffic patterns and adjust the number of instances accordingly. This is not applicable for fixed number of resources (option a), maintaining a specific CPU utilization (option c), or based on a specific CloudWatch metric (option d).
