This DBS-C01 practice question tests your understanding of monitoring and troubleshooting. 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 gaming company uses Amazon DynamoDB with provisioned capacity. During a new game launch, the read activity spikes and some requests receive 'ProvisionedThroughputExceededException' errors. The operations team needs to monitor read throttling in real-time. Which CloudWatch metric should they create an alarm for?
ReadLatency
Why wrong: Latency can increase due to throttling but does not directly count throttled requests.
ConsumedReadCapacityUnits
Why wrong: This shows consumed capacity, not throttled events.
ReadThrottleEvents
This metric specifically counts throttled read requests.
ThrottledRequests
Why wrong: ThrottledRequests is a sum of read and write throttles; not specific to reads.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
ReadThrottleEvents
Option B is correct because ReadThrottleEvents directly measures throttled read requests. Option A is wrong because ConsumedReadCapacityUnits shows actual usage, not throttled events. Option C is wrong because ThrottledRequests includes write throttles as well. Option D is wrong because ReadLatency shows latency, not throttling.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
ReadLatency
Why it's wrong here
Latency can increase due to throttling but does not directly count throttled requests.
ConsumedReadCapacityUnits
Why it's wrong here
This shows consumed capacity, not throttled events.
ReadThrottleEvents
Why this is correct
This metric specifically counts throttled read requests.

ThrottledRequests
Why it's wrong here
ThrottledRequests is a sum of read and write throttles; not specific to reads.
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.
Trap categories for this question
Command / output trap
This shows consumed capacity, not throttled events.
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.
