Quick Answer
The answer is the CloudWatch metric ReadThrottleEvents. This metric is correct because it directly counts the number of read requests that DynamoDB throttles due to exceeding the table’s provisioned read capacity, providing a precise measure of throttled read requests. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your ability to distinguish between CloudWatch metrics that track capacity consumption versus throttling events; a common trap is confusing ConsumedReadCapacityUnits, which only reflects successful reads, with throttling indicators. To avoid this, remember that any metric containing “Throttle” signals denied requests, while “Consumed” metrics track allowed usage. A useful memory tip: “ThrottleEvents” are the red flags for capacity violations, so when you need to monitor throttled read requests, always look for the word “Throttle” in the metric name.
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 developer needs to monitor the number of throttled read requests for a DynamoDB table. Which CloudWatch metric should be used?
ReadThrottleEvents
This metric directly counts throttled read requests.
ThrottledWriteEvents
Why wrong: This metric is for write throttles, not read.
SuccessfulRequestLatency
Why wrong: This metric measures latency, not throttles.
ConsumedReadCapacityUnits
Why wrong: This metric shows successful reads, not throttled ones.
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 C is correct because ReadThrottleEvents counts throttled read requests. Option A is wrong because ConsumedReadCapacityUnits shows successful reads, not throttled ones. Option B is wrong because ThrottledWriteEvents counts write throttles. Option D is wrong because SuccessfulRequestLatency measures latency, not throttles.
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.

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 metric shows successful reads, not throttled ones.
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.
