Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
CloudWatch Alarms
Why it's wrong here
While Alarms can trigger scaling, the Auto Scaling group's own health check mechanism is the primary driver for instance replacement.
- ✗
Elastic Load Balancer
Why it's wrong here
An ELB can be part of the health check, but the Scaling group's configuration is the control mechanism.
- ✗
IAM Role
Why it's wrong here
IAM roles handle permissions, not operational logic like health checks.
- ✓
Auto Scaling Health Checks
Why this is correct
Auto Scaling monitors instance health and replaces those that fail checks.
