Quick Answer

The answer is ALARM. This is because CloudWatch alarm evaluation periods determine how many consecutive data points must breach a threshold before the state changes, and here the EC2 instance’s CPU utilization averaged 85% for the last 10 minutes—exceeding a typical 80% threshold across the specified evaluation periods, which triggers the ALARM state. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this concept tests your understanding of how CloudWatch aggregates metric data over evaluation periods and transitions states based on sustained breaches, not single spikes. A common trap is confusing the number of evaluation periods with the total duration; remember that the alarm evaluates each period independently, and all must be in breach to move to ALARM. Memory tip: think “three strikes, you’re out”—each evaluation period is a strike, and the alarm only fires when every period in the window is a breach.

SAP-C02 Design for New Solutions Practice Question

This SAP-C02 practice question tests your understanding of design for new solutions. 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.

Answer choices

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

ALARM

The CLI output indicates that the alarm state is 'ALARM' because the EC2 instance's CPU utilization averaged 85% for the last 10 minutes, which exceeds the alarm threshold (typically set at, for example, 80% for a standard CPU utilization alarm). CloudWatch alarms transition to ALARM when the metric breaches the threshold for the specified evaluation periods, and here the sustained high utilization over the 10-minute window meets that condition.

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.

  • OK

    Why it's wrong here

    Threshold is breached.

  • ALARM

    Why this is correct

    2 consecutive periods of breaching threshold.

    Read the scenario before looking for a memorised answer.

  • INSUFFICIENT_DATA

    Why it's wrong here

    Sufficient data exists.

  • ERROR

    Why it's wrong here

    Not a valid state.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may confuse the alarm state with the metric value itself, assuming that a high metric value automatically means ALARM, but they must verify that the threshold and evaluation periods are met; however, in this case, the CLI explicitly shows the state as ALARM, so the answer is straightforward.

Detailed technical explanation

How to think about this question

CloudWatch alarms evaluate metrics based on a specified statistic (e.g., Average) over a period (e.g., 1 minute) and number of evaluation periods (e.g., 10 of 10). The alarm transitions to ALARM when the metric breaches the threshold for the configured datapoints to alarm (e.g., 10 out of 10 consecutive periods). In this scenario, the 85% average over 10 minutes implies all 10 data points exceeded the threshold, triggering ALARM. A real-world nuance: if the alarm uses 'Missing data treatment' set to 'breaching', missing points could artificially trigger ALARM, but here data is present.

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.
