How to approach this question
Identify the need to pause an ASG termination. Lifecycle hooks are designed for this.
Full Answer
B.Use an Auto Scaling lifecycle hook.✓ Correct
Use an Auto Scaling lifecycle hook.
Auto Scaling lifecycle hooks enable you to perform custom actions by pausing instances as an Auto Scaling group launches or terminates them. You can use a terminating lifecycle hook to pause the instance, upload logs, and then complete the termination.
Common mistakes
Thinking the cooldown period affects the termination process of a single instance.
