Exam Tips for Domain 3
Change sets preview CloudFormation changes; drift detection checks whether reality still matches the template.
Use immutable or blue/green deployment patterns when a rollback-safe release matters more than speed.
Systems Manager Run Command is good for one-time fleet actions; State Manager is better for desired-state enforcement.
EventBridge is often the simplest way to connect operational events to automated fixes.
