Topic 1 Question 353
A company runs an application on Amazon EC2 instances that are in an Amazon EC2 Auto Scaling group. Scale-out actions take a long time to become complete because of long-running boot scripts. A SysOps administrator must implement a solution to reduce the required time for scale-out actions without overprovisioning the Auto Scaling group.
Which solution will meet these requirements?
Change the launch configuration to use a larger instance size.
Increase the minimum number of instances in the Auto Scaling group.
Add a predictive scaling policy to the Auto Scaling group.
Add a warm pool to the Auto Scaling group.

It's D. Warm pools are used to have a group of instances already booted in stand-by to avoid initial scripts delay.
👍 4jas26says2023/06/23 warm pools do not directly address the issue of reducing the required time for scale-out actions caused by long-running boot scripts. Warm pools can help with quicker scaling by having pre-initialized instances, but they do not optimize the scaling process or reduce the impact of boot scripts during scale-out.
The correct approach to address the issue of long-running boot scripts and reduce the time for scale-out actions is to use predictive scaling, which is achieved through option C
