DBS-C01 Management and Operations Practice Question
Which TWO actions can be taken to monitor the health of an Amazon DynamoDB table? (Choose 2.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable Amazon CloudWatch metrics for the table
Enabling CloudWatch metrics for a DynamoDB table provides key health indicators such as read/write capacity utilization, throttled requests, and latency. Option E is correct because setting up CloudWatch alarms on ThrottledRequests allows you to proactively detect and respond to throttling events, which directly impacts table health. Option A is incorrect because AWS Trusted Advisor checks overall account limits but does not provide real-time health monitoring of a specific table. Option C is incorrect because DynamoDB Streams capture item-level changes for event-driven processing, not for monitoring the table's operational health. Option D is incorrect because DAX is an in-memory cache that improves read performance, not a monitoring tool.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use AWS Trusted Advisor to check table limits
Why it's wrong here
Trusted Advisor checks limits but does not monitor health in real-time.
- ✓
Enable Amazon CloudWatch metrics for the table
Why this is correct
CloudWatch metrics like ConsumedWriteCapacityUnits, ThrottledRequests indicate health.
- ✗
Enable DynamoDB Streams and process events with AWS Lambda
Why it's wrong here
Streams are for capturing changes, not health monitoring.
- ✗
Use DynamoDB Accelerator (DAX) to improve response times
Why it's wrong here
DAX is a caching layer, not a monitoring tool.
- ✓
Set up CloudWatch alarms for ThrottledRequests
Why this is correct
Alarms notify when throttling occurs, indicating potential health issues.
