AWS Certified SysOps Administrator SOA-C01 – Question463

A user has enabled instance protection for his Auto Scaling group that has spot instances. If Auto Scaling wants to terminate an instance in this Auto Scaling group due to a CloudWatch trigger unre-lated to bid price, what will happen?

A. Auto Scaling will notify the user for the next action
B. Auto Scaling will remove the instance from the Auto Scaling Group
C. Auto Scaling overwrites the instance termination attribute and terminates the instances
D. The EC2 instance will not be terminated since instance protection from scale-in is enabled.

Correct Answer: D

Explanation:

Explanation: Auto Scaling protects instances from termination during scale-in events. This means that Auto Scal-ing instance protection will receive the CloudWatch trigger to delete instances, and delete instances in the Auto Scaling group that do not have instance protection enabled. However, instance protec-tion won’t protect Spot instance termination triggered due to market price exceeding bid price. Reference:
