Correct answer & explanation
✓
Examine the ConsumedWriteCapacity and ThrottledWriteCount metrics in CloudWatch
A, C, D are correct. Examining CloudWatch metrics helps identify throttling patterns. Implementing exponential backoff is a best practice. Increasing provisioned capacity resolves throttling. B is wrong because enabling DynamoDB Streams does not affect throttling. E is wrong because changing consistency model does not affect write throttling.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Examine the ConsumedWriteCapacity and ThrottledWriteCount metrics in CloudWatch
Why this is correct
Helps identify if capacity is exceeded.
- ✗
Enable DynamoDB Streams to offload writes
Why it's wrong here
Streams do not reduce throttling.
- ✓
Implement exponential backoff in the application
Why this is correct
Retries with backoff handle throttling gracefully.
- ✓
Increase the write capacity units for the table
Why this is correct
More capacity reduces throttling.
- ✗
Change the read consistency to eventual
Why it's wrong here
Consistency does not affect write throttling.
