An organization has configured Auto Scaling with ELB. One of the instance health check returns the status as Impaired to Auto Scaling. What will Auto Scaling do in this scenario?

A. Perform a health che

ck until cool down before declaring that the instance has failed

B. Terminate the instance and launch a new instance

C. Notify the user using SNS for the failed state

D. Notify ELB to stop sending traffic to the impaired instance

Explanation:

The Auto Scaling group determines the health state of each instance periodically by checking the results of the Amazon EC2 instance status checks. If the instance status description shows any other state other than -running- or the system stat

us description shows impaired, Auto Scaling considers the instance to be unhealthy. Thus, it terminates the instance and launches a replacement.
