AWS Certified SysOps Administrator – Associate (legacy) — Question 275

A sys admin is trying to understand the Auto Scaling activities. Which of the below mentioned processes is not performed by Auto Scaling?

Answer options

• A. Reboot Instance
• B. Schedule Actions
• C. Replace Unhealthy
• D. Availability Zone Balancing

Correct answer: A

Explanation

Auto Scaling manages instance lifecycle by launching, terminating, and replacing unhealthy instances, as well as balancing them across Availability Zones and executing scheduled actions. It does not natively perform a reboot operation on instances; instead, unhealthy instances are terminated and completely replaced to maintain application availability.
