Explanation: AutoScaling rounds off the values returned by the PercentChangeInCapacity to the higher number if value is negative. If the current count is 53 and the policy gets executed, the total number of instances to be decreased will be calculated as 5.3 (10% of 53). AWS will round it off to 5 and terminate 5 more instances.

Correct Answer : Get Lastest Questions and Answer :
Explanation: When a user is creating a new launch configuration from the existing instance, AS will take all the parameters except the instance ID and config name from the existing instance. The launch config though, will not take the new block device mapping into consideration and instead use the one which was the default one with AMI. In this case there was no additional block device with EBS. Thus, the future EBS will have 0 additional EBS volumes
