SOA-C02 Monitoring, Logging, and Remediation Practice Question
This SOA-C02 practice question tests your understanding of monitoring, logging, and remediation. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 has a CloudWatch alarm that monitors the CPU utilization of an EC2 instance. The alarm is set to trigger when CPU utilization exceeds 80% for 5 consecutive minutes. The alarm state is 'INSUFFICIENT_DATA'. What does this mean?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The alarm does not have enough data to determine the state.
The INSUFFICIENT_DATA state in CloudWatch indicates that the alarm has not received enough metric data points to evaluate whether the threshold (CPU utilization > 80% for 5 consecutive minutes) has been breached. This typically occurs when the EC2 instance is newly launched, the CloudWatch agent is not reporting, or there are gaps in metric collection due to network issues or instance stops. It does not imply any conclusion about the CPU utilization level itself.
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.
✗
The CPU utilization is below 80% for 5 minutes.
Why it's wrong here
That would be OK state.
✗
The CPU utilization has exceeded 80% for 5 minutes.
Why it's wrong here
That would be ALARM state.
✓
The alarm does not have enough data to determine the state.
Why this is correct
INSUFFICIENT_DATA indicates that the metric has not provided enough data points for evaluation.
Related concept
Read the scenario before looking for a memorised answer.
✗
The alarm is missing data points for the past 5 minutes.
Why it's wrong here
Insufficient data can be due to missing data points, but the state specifically means not enough data to determine.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse INSUFFICIENT_DATA with missing data points for the exact evaluation period, but the state actually means the alarm cannot determine whether the threshold is breached due to a lack of sufficient data across the configured evaluation periods, not just the last 5 minutes.
Detailed technical explanation
How to think about this question
CloudWatch alarms evaluate metric data based on the number of evaluation periods (e.g., 5 consecutive minutes) and the statistic (e.g., Average). The INSUFFICIENT_DATA state occurs when fewer than the required number of data points are available within the evaluation window—for example, if the metric is published every 5 minutes but the alarm expects a data point every minute. This is common with custom metrics that have sporadic reporting or when an EC2 instance is in a stopped state, as CloudWatch stops receiving CPU utilization data from the hypervisor.
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
