This PAS-C01 practice question tests your understanding of operations and maintenance. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An SAP administrator needs to ensure that an EC2 instance hosting SAP HANA is rebooted automatically after a hardware failure. Which AWS feature provides this capability?
Placement group
Why wrong: Placement groups influence network latency, not recovery.
Auto Scaling group
Why wrong: Auto Scaling groups manage scaling, not automatic recovery.
EC2 Auto Recovery
Auto Recovery automatically recovers an instance from hardware failure.
Elastic IP address
Why wrong: Elastic IP addresses are static IPs, not recovery.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
EC2 Auto Recovery
EC2 Auto Recovery is the correct AWS feature because it automatically recovers an EC2 instance when a hardware failure on the underlying physical host is detected. For SAP HANA workloads, this ensures the instance is rebooted on a healthy host without manual intervention, maintaining high availability for critical database operations.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Placement group
Why it's wrong here
Placement groups influence network latency, not recovery.
Auto Scaling group
Why it's wrong here
Auto Scaling groups manage scaling, not automatic recovery.
EC2 Auto Recovery
Why this is correct
Auto Recovery automatically recovers an instance from hardware failure.

Elastic IP address
Why it's wrong here
Elastic IP addresses are static IPs, not recovery.
Common exam traps
The trap here is that candidates often confuse Auto Scaling groups (which replace instances) with EC2 Auto Recovery (which recovers the same instance), leading them to choose Auto Scaling for automatic reboot, but Auto Scaling does not reboot the same instance and can cause data loss for stateful applications like SAP HANA.
Detailed technical explanation
EC2 Auto Recovery uses the instance's status checks (system status check and instance status check) to detect hardware impairments. When a system status check fails (indicating a physical host issue), AWS automatically stops and starts the instance on a new host, preserving the instance ID, private IP, and EBS volumes. For SAP HANA, this is critical because the instance ID and attached storage must remain consistent to avoid database corruption, and the recovery action can be configured via the `aws ec2 create-recovery-instance` CLI or the AWS Management Console.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
