Question 50
An accounts-payable department needs to extract invoice fields and table cells from scanned PDF documents. After selecting the recommended approach, which evidence MOST DIRECTLY demonstrates that the actual required outcome has been achieved?
- A component test invokes this alternate approach successfully: Use Amazon Translate to extract source PDF table coordinates
- Verify vendor, amount and line-item fields against reviewed sample invoices
- A reviewed design record approves this competing approach: Use Amazon Polly to read the scanned PDF as an invoice database
- A system inventory lists this competing approach as active: Use Amazon Rekognition general object labels as the invoice parser
Explanation
Correct Answer
B:Verify vendor, amount and line-item fields against reviewed sample invoices. This checks the business result rather than just a configured feature.
Incorrect Answers
A:Language translation does not identify document tables and fields A component invocation does not validate the necessary end-to-end outcome.
C:Speech synthesis does not parse scanned invoice forms Design approval is not evidence that the alternative meets the actual requirement.
D:Visual object labels do not reconstruct invoice form keys and table cell structure An active setting cannot independently prove the requested business outcome.

Question 54
An online checkout system must return a fraud score while the customer is still waiting. Which option BEST meets the business requirement?
- Schedule a single nightly batch job for all checkout requests
- Use a translation pipeline as the fraud scoring endpoint
- Use real-time inference with measured response latency
- Require humans to retrain the model before every purchase
Explanation
Correct Answer
C:An interactive decision requires an endpoint meeting the application's latency budget The specified scenario makes this the most appropriate approach.
Incorrect Answers
A:Nightly batch results arrive after the checkout decision window This prevents the approach from meeting the stated requirement.
B:Translating purchase descriptions is not a fraud score This prevents the approach from meeting the stated requirement.
D:Model training is separate from serving each inference request This prevents the approach from meeting the stated requirement.
Question 55
An accounts-payable department needs to extract invoice fields and table cells from scanned PDF documents. A pilot uses this approach instead: Use Amazon Rekognition general object labels as the invoice parser. Which limitation MOST DIRECTLY explains why the requirement is not met?
