Exhibit

Refer to the exhibit.

```json
{
  "skills": [
    {
      "@odata.type": "#Microsoft.Skills.Text.SplitSkill",
      "name": "#1",

A law firm uses Azure Document Intelligence to extract clauses from legal contracts. They have a custom model trained on 15 labeled contracts. The model extracts clauses with high confidence on similar documents but fails to extract correct clauses from a new batch of contracts that have a different font and layout. The firm needs to improve extraction accuracy without retraining the model from scratch. The solution must minimize manual effort and cost. What should they do?

Trap 1: Use the prebuilt-layout model to extract clauses instead

Prebuilt models do not extract custom clauses.

Trap 2: Increase the OCR confidence threshold in the analysis request

OCR confidence threshold does not affect layout adaptation.

Trap 3: Label 15 more contracts with the original layout and retrain the…

This does not address the new layout variation.

A company uses Azure Cognitive Search to index customer support emails. They need to implement a custom skill that extracts the sentiment of the email body and also identifies the primary product mentioned. The custom skill is a Python function deployed as an Azure Function. They want to ensure the skill can process multiple documents concurrently and handle errors gracefully. Which THREE configurations should they apply?

Trap 1: Set continueOnError to false to ensure that if the skill fails for…

Setting continueOnError to false would cause the entire run to fail; it's better to set it to true to skip failures for individual documents.

Trap 2: Set the context property to '/document/pages/*' to process each…

Emails are not paginated; setting context to '/document' is appropriate to process the entire document.

Study all Implement knowledge mining and document intelligence solutions common traps →

A
Set continueOnError to false to ensure that if the skill fails for one document, the entire indexer run stops.
Why wrong: Setting continueOnError to false would cause the entire run to fail; it's better to set it to true to skip failures for individual documents.
B
Set the inputs of the skill to include the 'text' field from the enriched document and the 'product' field from a previous skill.
Inputs define the data passed to the skill; they should reference fields from the enrichment pipeline.
C
Set the uri of the skill to the HTTP endpoint of the Azure Function, including the function key.
Custom skills must point to the function's endpoint; Azure Functions are typically accessed via an HTTP URL with a code or key.
D
Set the context property to '/document/pages/*' to process each page of the email individually.
Why wrong: Emails are not paginated; setting context to '/document' is appropriate to process the entire document.
E
Set the batchSize of the custom skill definition to 10 to allow parallel processing of multiple documents.
A higher batchSize allows the indexer to send multiple documents per skill invocation, improving throughput.

Question 10mediummultiple choice

Read the full Implement knowledge mining and document intelligence solutions explanation →

You are a developer for a legal firm. The firm uses Azure Cognitive Search to index legal documents. They have a custom skill that performs OCR on scanned PDFs using Azure Form Recognizer. The skill is implemented as an Azure Function. Recently, the indexer has been failing with the error: "The request was canceled due to the configured HttpClient.Timeout of 100 seconds elapsing." The documents are large (up to 200 pages each). The skill calls the Form Recognizer API asynchronously. You need to resolve the timeout issue without losing the ability to process large documents. Current configuration: batchSize = 1, maxPageSize = 100, timeout = 100 seconds. You cannot change the execution time of the Form Recognizer API. What should you do?

Trap 1: Increase the batchSize to 10 to process more documents per…

Increasing batchSize would cause the function to receive more documents per call, making the timeout issue worse.

Trap 2: Increase the maxPageSize to 500 to reduce the number of API calls…

Form Recognizer has its own limits; increasing maxPageSize beyond the maximum supported will result in errors.

Trap 3: Remove the custom skill and use the built-in OCR skill in the…

The built-in OCR skill may not integrate with Form Recognizer's advanced features; the question requires using the existing custom skill.

Study all Implement knowledge mining and document intelligence solutions common traps →

A
Increase the batchSize to 10 to process more documents per invocation, reducing the number of total invocations.
Why wrong: Increasing batchSize would cause the function to receive more documents per call, making the timeout issue worse.
B
Increase the maxPageSize to 500 to reduce the number of API calls to Form Recognizer.
Why wrong: Form Recognizer has its own limits; increasing maxPageSize beyond the maximum supported will result in errors.
C
Decrease the batchSize to 1 and increase the timeout property in the skillset skill definition to PT300S.
Increasing the skill timeout to 300 seconds allows the function more time to process the document. The function's timeout must also be increased in host.json.
D
Remove the custom skill and use the built-in OCR skill in the skillset.
Why wrong: The built-in OCR skill may not integrate with Form Recognizer's advanced features; the question requires using the existing custom skill.
