- A
Auto Scaling group with a scheduled scaling policy
Why wrong: Auto Scaling adds/removes instances, but recovery requires Auto Recovery.
- B
Elastic Load Balancer health checks
Why wrong: ELB distributes traffic, it doesn't recover instances.
- C
EC2 Auto Recovery with CloudWatch alarms
Auto Recovery automatically recovers the instance.
- D
Manual restart of the instance from the AWS Management Console
Why wrong: Manual restart is not automatic.
Question 872 of 1,733
Automatically Recover SAP EC2 Instances with EC2 Auto Recovery
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A company is deploying SAP on AWS and wants to ensure that the SAP system can automatically recover from an EC2 instance failure. Which AWS feature should be used?

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
✓
EC2 Auto Recovery with CloudWatch alarms
EC2 Auto Recovery, configured via a CloudWatch alarm based on the StatusCheckFailed metric, automatically recovers an EC2 instance by restarting it on a new host if the underlying hardware fails or becomes impaired. This is the correct AWS feature for automatic recovery from an EC2 instance failure, as it directly addresses instance-level hardware issues without requiring manual intervention or reconfiguration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
Manual restart is not automatic.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Elastic Load Balancer health checks with instance recovery, but ELB only manages traffic distribution and does not perform any recovery action on the instance itself.
Detailed technical explanation
How to think about this question
EC2 Auto Recovery works by monitoring the StatusCheckFailed metric (which includes both system status checks and instance status checks) via a CloudWatch alarm. When the alarm triggers, AWS automatically stops and starts the instance on a new healthy host, preserving the instance ID, private IP, Elastic IP, and EBS volumes. However, it does not recover from instance status check failures caused by OS-level issues (e.g., kernel panic) unless the instance is configured to automatically reboot; for such cases, a custom CloudWatch alarm with a reboot action is needed.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
