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
✓
WriteThrottleEvents
'WriteThrottleEvents' is the Amazon CloudWatch metric that directly indicates throttled write requests. Option A is wrong because 'ThrottledWriteRequests' is not a standard CloudWatch metric name (the correct name is WriteThrottleEvents). Option C is wrong because 'ProvisionedWriteCapacityUnits' is not applicable for on-demand capacity. Option D is wrong because 'ConsumedWriteCapacityUnits' shows actual usage, not throttling.
