reated a new AMI after updating one of the instances. If the user wants to terminate two specific instances to ensure that Auto Scaling launches an instances with the new launch configuration, which command should he run?

A. as-delete-instance-in-auto-sca

ling-group –no-decrement-desired-capacity

B. as-terminate-instance-in-auto-scaling-group –update-desired-capacity

C. as-terminate-instance-in-auto-scaling-group –decrement-desired-capacity

D. as-terminate-instan

ce-in-auto-scaling-group –no-decrement-desired-capacity

Explanation:

The Auto Scaling command as-terminate-instance-in-auto-scaling-group will terminate the specific instance ID. The user is required to specify the

parameter as -no-decrement-desired-capacity to ensure that it launches a new instance from the launch config after terminating the instance. If the user specifies the parameter –decrement-desired-capacity then Auto Scaling will terminate the instance and

decrease the desired capacity by 1.
