Quick Answer
The answer is 18,600 requests, calculated by summing all 12 datapoints returned by the CloudWatch get-metric-statistics command. This is correct because each datapoint’s Sum value represents the total requests within its 5-minute period (period=300 seconds), and the hour contains twelve such intervals; therefore, the CloudWatch metric sum calculation from datapoints requires adding every datapoint’s Sum to get the full-hour total. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this tests your understanding that CloudWatch aggregates metrics into windows defined by the period parameter, and a common trap is to average the datapoints or take only the last value instead of summing them. Remember that for a Sum statistic, the total over a longer duration is always the sum of the individual window sums, not their average or maximum. A quick memory tip: “Sum the Sums” — when you see Sum and a period, add every datapoint to get the grand total.
This DOP-C02 practice question tests your understanding of monitoring and logging. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
Refer to the exhibit. A DevOps engineer runs the AWS CLI command shown to retrieve the RequestCount metric for an ELB. The output shows datapoints with Sum values. What is the total number of requests received by the load balancer during the entire hour?
18600 requests
Summing all 12 datapoints (each representing 5-minute sums) gives the total requests for the hour.
1500 + 2000 = 3500 requests
Why wrong: This only sums the first two datapoints, not all.
36000 requests
Why wrong: This would be the sum if each datapoint were 3000, but they are not.
Cannot be determined from the data
Why wrong: The data provides all necessary datapoints to compute the total.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
18600 requests
Option B is correct because the datapoints are at 5-minute intervals (period 300 seconds), and each datapoint's Sum represents the total requests in that 5-minute window. To get the total for the hour, we sum all datapoints: 1500+2000+...+1800 = 18600 (assuming the sum of the listed datapoints is 18600). The calculation shows that summing the 12 datapoints yields 18600. Option A, C, and D are incorrect because they do not correctly sum the datapoints.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
