Q17 Single choice

A streaming services company has a three-tier web application hosted on Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer (ALB). When the Auto Scaling group scales in, a deregistration delay occurs and the delay is sometimes longer than the time required to terminate the EC2 instance. A SysOps administrator must ensure that the latest logs are delivered to an external system

before the EC2 instance is terminated.

Which solution will solve this problem?

A
Add a lifecycle hook to the Auto Scaling group to put the EC2 instance in a wait state until the log files have been delivered.
B
Configure a fixed response for the ALB to use custom error messages to respond to incoming requests with HTTP error response codes.
C
Create an Amazon CloudWatch alarm based on the RequestCountPerTarget metric for the Auto Scaling group. Modify the cooldown period to wait until the EC2 instance is terminated.
D
Update the launch configuration to enable scale-in protection for the Auto Scaling group and detach the EC2 instance protected for termination.
