Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create an AMI snapshot before applying patches

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use AWS CloudFormation to re-create the instance
Why it's wrong here
Re-creating from CloudFormation may be slower than restoring a snapshot.
- ✓
Create an AMI snapshot before applying patches
Why this is correct
An AMI snapshot allows you to revert the instance to its pre-patch state.
- ✗
Configure a rollback procedure using AWS Systems Manager State Manager
Why it's wrong here
State Manager enforces configuration, not rollback of patches.
- ✗
Enable termination protection on the instances
Why it's wrong here
Termination protection prevents accidental deletion, not patch rollback.
