The answer is to review the instance's status check history in the EC2 console. This is the correct first step because it allows you to distinguish between a system status check failure, which indicates an AWS hardware or network issue, and an instance status check failure, which points to OS-level problems like memory exhaustion or a corrupted file system. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this question tests your understanding of the diagnostic workflow before taking action—especially in an Auto Scaling context, where a common trap is to immediately terminate or replace the instance, which can mask the root cause and lead to cascading failures. The exam emphasizes that you must first gather historical data to identify the failure pattern, as this informs whether you need to stop and start the instance (for system issues) or reboot and investigate the OS (for instance issues). A helpful memory tip: “History first, action last—check the log before you pull the plug.”
SOA-C02 Monitoring, Logging, and Remediation Practice Question
This SOA-C02 practice question tests your understanding of monitoring, logging, and remediation. 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 SysOps admin notices that an EC2 instance's status check fails intermittently. The instance is part of an Auto Scaling group. What is the most appropriate first step to diagnose the issue?

Correct answer & explanation
✓
Review the instance's status check history in the EC2 console
The most appropriate first step is to review the instance's status check history in the EC2 console (Option D). This allows the SysOps admin to determine whether the failures are due to system status checks (e.g., underlying hardware issues) or instance status checks (e.g., OS-level problems). Since the instance is part of an Auto Scaling group, understanding the root cause is critical before taking any corrective action, as premature termination or reboot could mask the issue or lead to unnecessary replacements.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Stop and start the instance
Why it's wrong here
Stop/start moves the instance to new hardware but is not the first diagnostic step.
✗
Terminate the instance and let Auto Scaling replace it
Why it's wrong here
Termination should be a last resort after investigation.
✗
Reboot the instance
Why it's wrong here
Rebooting might temporarily fix but doesn't diagnose the root cause.
✓
Review the instance's status check history in the EC2 console
Why this is correct
Status checks reveal whether the issue is system-level or instance-level.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often jump to terminating or rebooting the instance immediately, but the SOA-C02 exam emphasizes a methodical troubleshooting approach where reviewing status check history is the first step to differentiate between recoverable and irrecoverable failures.
Detailed technical explanation
How to think about this question
EC2 status checks consist of two types: system status checks (monitoring AWS hardware/software) and instance status checks (monitoring the guest OS and applications). The status check history in the EC2 console provides a timeline of these checks, including the specific failure reason (e.g., 'Insufficient data' or 'Instance reachability check failed'). In an Auto Scaling group, understanding whether the failure is systemic (e.g., underlying hardware degradation) or instance-specific (e.g., memory exhaustion) determines whether to use a lifecycle hook for custom remediation or to adjust the Auto Scaling group's health check grace period.

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.
