A company is using an Amazon EC2 Auto Scaling group to support a workload A Sytfhe company now needs to centruito Scaling group is configured with two similar scaling policies dP) to centrally manage access to One scaling policy adds 5 instances when CPU utilization reaches 80%. The other sctrator can connect to the extemahen CPU utilization leaches 80%.

What will happen when CPU utilization reaches the 80% threshold?

Show Suggested Answer Hide Answer
Suggested Answer: B

Scaling Policies in Auto Scaling:

When multiple scaling policies trigger at the same time, each policy is executed independently.

If both policies are set to add 5 instances when CPU utilization reaches 80%, they will both be executed when the threshold is met.

Therefore, the total number of instances added will be the sum of the instances specified in both policies.

In this case, 5 instances from one policy and 5 instances from the other policy will result in a total of 10 instances being added.

Steps to Configure and Verify Scaling Policies:

Go to the AWS Management Console.

Navigate to EC2 and select 'Auto Scaling Groups.'

Select your Auto Scaling group and review the scaling policies.

Ensure that both scaling policies are configured to trigger at 80% CPU utilization.

Monitor the Auto Scaling group's activity to verify the addition of instances when the CPU utilization threshold is reached.

So, the scaling group will add 5 instances first, and then evaluate the second policy.

In that case, the scaling policies will be evaluated in the order they were created.

Haha, this question is testing our ability to read and comprehend. D is the only logical choice here. I mean, who wants 15 instances when you asked for 5? That's just overkill!

Obviously, the right answer is D. Conflicting scaling policies? That's a recipe for disaster! No scaling for you!

Hmm, I think the correct answer is D. The conflicting policies will prevent the Auto Scaling group from scaling up properly.

But what if both policies are triggered at the same time?

I agree with Terry, because one policy adds 5 instances when CPU reaches 80%.
