This DEA-C01 practice question tests your understanding of data operations and support. 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.
Which TWO actions are effective ways to monitor the health of an Amazon DynamoDB table? (Choose two.)
Use AWS S3 inventory to track table size.
Why wrong: S3 inventory is for S3.
Use EC2 instance status checks.
Why wrong: Not relevant to DynamoDB.
Enable DynamoDB Streams and process with Lambda to detect failures.
Streams can be used for monitoring changes.
Set up Amazon CloudWatch alarms on ConsumedReadCapacityUnits.
Monitors read throughput.
Monitor the 'TableHealth' metric in CloudWatch.
Why wrong: No such metric exists.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Enable DynamoDB Streams and process with Lambda to detect failures.
Options A and D are correct. CloudWatch metrics like ConsumedReadCapacityUnits and ThrottledRequests provide insight into table health. Option B is wrong because there is no 'TableHealth' metric. Option C is wrong because S3 is not for DynamoDB monitoring. Option E is wrong because EC2 is not relevant.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
