DBS-C01 Monitoring and Troubleshooting Practice Question
A company is running a production Amazon DynamoDB table with on-demand capacity. The application is experiencing increased latency and throttled requests during peak hours. Which monitoring tool should the database specialist use to identify the specific partition keys causing the throttling?
⚠ Common exam trap
Many candidates confuse CloudTrail (which logs all API calls) with Contributor Insights, assuming CloudTrail can provide per-key throttling data, but CloudTrail lacks the aggregation and top-N analysis needed to identify specific hot partition keys.

Correct answer & explanation
✓
Amazon CloudWatch Contributor Insights for DynamoDB
Amazon CloudWatch Contributor Insights for DynamoDB is the correct tool because it analyzes DynamoDB request logs to identify the most frequently accessed partition keys, including those causing throttling. It provides top-N keys by request count or throttled events, enabling the database specialist to pinpoint hot partitions responsible for increased latency and throttled requests during peak hours.
