Auto Scaling — AWS Solutions Architect Associate Practice Questions
Auto scaling allows AWS resources, most commonly EC2 instances and ECS tasks, to adjust capacity automatically in response to demand, scheduled events, or predictive models. The exam covers EC2 Auto Scaling groups, scaling policies (target tracking, step, simple), and the difference between scaling out (adding instances) and scaling up (increasing instance size). You must understand how Auto Scaling integrates with Elastic Load Balancing, health checks, and lifecycle hooks to build resilient architectures. Correctly sizing minimum, desired, and maximum capacity values is a recurring exam scenario.
