The user has configured AutoScaIing based on the dynamic policy. Which of the following is not the right command to specify a change in capacity as a part of the policy?

1. A. "adjustment=-50" (type is PercentChangeInCapacity)
2. B. "adjustment=3" (type is ExactCapacity)
3. C. "adjustment=-1" (type is ChangeInCapacity)
4. D. "adjustment=-8" (type is ExactCapacity)

Correct Answer: D
The user can configure the AutoScaIing group to automatically scale up and then scale down based on the various specified CIoudWatch monitoring conditions. The user needs to provide the adjustment value and the adjustment type. A positive adjustment value increases the current capacity and a negative adjustment value decreases the current capacity. The user can express the change to the current size as an absolute number, an increment or as a percentage of the current group size.
In this option specifying the exact capacity with the adjustment value = -8 will not work as when type is exact capacity the adjustment value cannot be negative.

Correct Answer: C
With AWS Identity and Access Management (IAM), you can create IAM users to control who has access to which resources in your AWS account.

In addition to AWS CIoudFormation actions, you can manage what AWS services and resources are available to each user.

Correct Answer: A
An EC2 instance, once terminated, may be available in the AWS console for a while after termination.

If the user has explicitly stopped or terminated the instance, the reason will be "User initiated shutdown".
