Topic 1 Question 474
A company is using an Amazon EC2 Auto Scaling group to support a workload. A SysOps administrator finds that the Auto Scaling group is configured with two similar scaling policies.
One scaling policy adds 5 instances when CPU utilization reaches 80%. The other scaling policy adds 10 instances when CPU utilization reaches 80%.
What will happen when CPU utilization reaches the 80% threshold?
Amazon EC2 Auto Scaling will add 5 instances.
Amazon EC2 Auto Scaling will add 10 instances.
Amazon EC2 Auto Scaling will add 15 instances.
The Auto Scaling group will not scale because of conflicting policies.

When these situations occur, Amazon EC2 Auto Scaling chooses the policy that provides the largest capacity for both scale out and scale in.

Logically, 10 instances should scale up with 80% utilization as it may not add with the previous instances so going with B here...
👍 1Aamee2024/10/29 I thought it was 10 as well, but chatGPT stated 15>>>> When the CPU utilization of the Auto Scaling group reaches the 80% threshold, both scaling policies will trigger concurrently because they are configured with the same condition (CPU utilization reaching 80%). As a result:
The first scaling policy will attempt to add 5 instances. The second scaling policy will attempt to add 10 instances. This will result in the Auto Scaling group trying to launch a total of 15 new instances simultaneously.
