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 check 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
Suggested Answer:B🗳️
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 ג€runningג€ or the system status description shows impaired, Auto Scaling considers the instance to be unhealthy. Thus, it terminates the instance and launches a replacement.
Auto Scaling will notify the ELB to stop sending traffic to the impaired instance, allowing the organization to focus on troubleshooting and resolving the issue with the instance without impacting the overall availability and performance of the application.
