AWS Certified SysOps Administrator – Associate (legacy) — Question 373

A user is planning to scale up an application by 8 AM and scale down by 7 PM daily using Auto Scaling. What should the user do in this case?

Answer options

• A. Setup the scaling policy to scale up and down based on the CloudWatch alarms
• B. The user should increase the desired capacity at 8 AM and decrease it by 7 PM manually
• C. The user should setup a batch process which launches the EC2 instance at a specific time
• D. Setup scheduled actions to scale up or down at a specific time

Correct answer: D

Explanation

Scheduled scaling allows Auto Scaling to scale an application automatically based on predictable load changes at specific times of the day. CloudWatch alarms are designed for dynamic scaling based on metrics rather than fixed schedules, while manual adjustments and custom batch processes introduce unnecessary operational overhead.
