Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create AMI snapshots of instances before patching
Why this is correct
Snapshots allow restoring the pre-patch state if needed.
- ✓
Configure a maintenance window for the patching operation
Why this is correct
Maintenance windows schedule patching during defined periods to minimize impact.
- ✗
Enable auto-scaling to replace instances if patching fails
Why it's wrong here
Auto-scaling does not directly provide rollback; it replaces instances based on load.
- ✗
Use AWS Config to verify patch compliance after patching
Why it's wrong here
Config can check compliance but is not a rollback mechanism.
- ✗
Set the patch baseline to automatically approve all patches
Why it's wrong here
Auto-approving all patches increases risk and does not provide rollback.
