AWS Certified SysOps Administrator – Associate (legacy) — Question 283

A user is planning to setup infrastructure on AWS for the Christmas sales. The user is planning to use Auto Scaling based on the schedule for proactive scaling.
What advice would you give to the user?

Answer options

• A. It is good to schedule now because if the user forgets later on it will not scale up
• B. The scaling should be setup only one week before Christmas
• C. Wait till end of November before scheduling the activity
• D. It is not advisable to use scheduled based scaling

Correct answer: C

Explanation

AWS Auto Scaling allows you to schedule scaling activities, but one-time scheduled actions can only be configured up to a maximum of one month in advance. Therefore, trying to set up the schedule too far in advance will fail, making the end of November the most appropriate time to configure the action for December. Scheduled scaling is highly recommended for predictable traffic spikes like holiday sales, ruling out option D, while option B leaves too narrow a window for testing.
