PAS-C01 Technology Practice Question
A company is running SAP HANA on a bare metal EC2 instance. The system experiences a hardware failure that causes an instance stop. The company needs to recover the instance quickly. What should the company do to minimize recovery time?
⚠ Common exam trap
The trap here is that candidates mistakenly think manual restart (Option B) or snapshot restore (Option C) are faster, but they overlook that CloudWatch automatic recovery is the only option that preserves the instance identity and minimizes downtime for hardware failures on bare metal instances.

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
✓
Configure an Amazon CloudWatch alarm to automatically recover the instance
Amazon CloudWatch can automatically recover an impaired EC2 instance by restarting it on new underlying hardware, preserving the instance ID, private IP, Elastic IP, and EBS attachments. This minimizes recovery time by eliminating manual intervention and leveraging AWS's automated recovery mechanism, which is specifically designed for hardware failures on bare metal instances like those running SAP HANA.
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 recreate the instance
Why it's wrong here
CloudFormation template execution is not automatic recovery.
- ✗
Manually start the instance from the EC2 console
Why it's wrong here
Manual recovery takes time and requires human intervention.
- ✗
Restore the instance from the latest EBS snapshot
Why it's wrong here
Restoring from snapshot takes longer than recovery.
- ✓
Configure an Amazon CloudWatch alarm to automatically recover the instance
Why this is correct
CloudWatch can automatically recover an instance on healthy hardware.
