Topic #: 1

A user is trying to setup a recurring Auto Scaling process. The user has setup one process to scale up every day at 8 am and scale down at 7 PM. The user is trying to setup another recurring process which scales up on the 1st of every month at 8 AM and scales down the same day at 7 PM. What will Auto Scaling do in this scenario?

A. Auto Scaling will execute both processes but will add just one instance on the 1st
B. Auto Scaling will add two instances on the 1st of the month
C. Auto Scaling will schedule both the processes but execute only one process randomly
D. Auto Scaling will throw an error since there is a conflict in the schedule of two separate Auto Scaling Processes

Show Suggested Answer

Suggested Answer: D 🗳️
Auto Scaling based on a schedule allows the user to scale the application in response to predictable load changes. The user can also configure the recurring schedule action which will follow the Linux cron format. As per Auto Scaling, a scheduled action must have a unique time value. If the user attempts to schedule an activity at a time when another existing activity is already scheduled, the call will be rejected with an error message noting the conflict.
