AI-103 Information Extraction Solutions Sample Questions with Answers

Sample Question 1 — Implement information extraction solutions

A team is digitizing scanned warehouse inspection checklists. Their rules engine needs table rows, checkbox states, and reading order from each page, but it does not yet need business-specific fields such as an inspection score. Which approach should the developer choose first?

  1. A. Use OCR-only text extraction on each page
  2. B. Use layout analysis to preserve structure and selection marks (Correct answer)
  3. C. Use a prebuilt invoice extraction model for normalized fields
  4. D. Use a chat model to summarize each checklist into free text

Correct answer: B

Explanation: Correct answer (B): Layout analysis is the best first step because the rules engine depends on document structure, not just plain text. It preserves tables, selection marks, and reading order, which are critical for deterministic downstream processing. OCR-only extraction can read text but will not reliably preserve those relationships. Prebuilt invoice extraction targets invoice fields, and summarization would throw away the structure the rules engine needs. Why the other options are wrong: - Option A: OCR-only processing can recover text, but it does not preserve tables, selection marks, or reading order well enough for structural rule processing. - Option C: Prebuilt invoice models are intended for invoice-specific normalized fields, not general checklist structure. - Option D: A free-text summary is not appropriate when the downstream system needs deterministic structural elements from the page.

Sample Question 2 — Implement information extraction solutions

An accounts payable app must process supplier invoices from many vendors. The app needs standardized fields such as vendor name, invoice total, and due date for downstream approval rules. What is the best Azure-native extraction choice?

  1. A. Extract raw text with OCR and parse totals with prompt-based summarization
  2. B. Run layout analysis only and let downstream code infer every field
  3. C. Use a prebuilt document extraction model for invoices (Correct answer)
  4. D. Index scanned PDFs directly in Azure AI Search without field extraction

Correct answer: C

Explanation: Correct answer (C): A prebuilt invoice extraction model is the best fit because invoices are a common document type and the application needs normalized business fields such as totals and due dates. Specialized extraction is more reliable for deterministic invoice fields than OCR plus prompting or layout-only output. Search indexing can support retrieval later, but it does not replace field extraction for approval workflows. Why the other options are wrong: - Option A: OCR plus prompting may work inconsistently, but it is usually less reliable than specialized invoice extraction for deterministic fields. - Option B: Layout analysis preserves structure, but it does not by itself return normalized invoice fields such as vendor name or invoice total. - Option D: Azure AI Search helps with retrieval after extraction, but it does not replace extraction of the fields needed for downstream approval logic.

Sample Question 3 — Implement information extraction solutions

A manufacturer receives compliance certificates from partner labs. The certificates contain company-specific labels and proprietary test-result sections that do not match common invoice, receipt, or ID patterns. The business needs reliable structured JSON mapped to its internal schema. Which approach is best?

  1. A. Use a prebuilt receipt model because both are semi-structured documents
  2. B. Use custom extraction aligned to the organization's schema (Correct answer)
  3. C. Use keyword search across OCR text and infer fields later
  4. D. Use generic document summarization and store the summary as JSON

Correct answer: B

Explanation: Correct answer (B): Custom extraction is the best answer because the documents are domain-specific and must map to a known internal schema. Prebuilt models are best for common document categories such as invoices, receipts, or IDs, but this scenario describes proprietary sections and labels that do not match those patterns. Search and summarization may help later, but they are not reliable substitutes for validated structured JSON. Why the other options are wrong: - Option A: A prebuilt receipt model is designed for a different common document type and is not the best fit for proprietary compliance certificates. - Option C: Keyword search over OCR text can help retrieval, but it is weak when the primary requirement is deterministic structured extraction. - Option D: A summary is not a substitute for schema-aligned, validated structured JSON.

Sample Question 4 — Implement information extraction solutions

A legal assistant app already extracts text and clause metadata from contracts. Users ask natural-language questions such as "Which contracts renew automatically next quarter?" and expect cited passages. Which search design is best for the chat layer?

  1. A. Store only nightly summaries and answer from the summaries
  2. B. Use keyword-only search over raw OCR output
  3. C. Index extracted text and metadata in Azure AI Search with hybrid or vector-assisted retrieval (Correct answer)
  4. D. Skip retrieval and rely on a larger chat model for answers

Correct answer: C

Explanation: Correct answer (C): The chat experience needs grounded answers with citations over extracted contract content. Indexing extracted text plus metadata in Azure AI Search enables retrieval of the right source passages, and hybrid or vector-assisted retrieval is usually better than keyword-only search for natural-language questions. Summaries and a larger model do not replace retrieval from source content when evidence and citations matter. Why the other options are wrong: - Option A: Nightly summaries can omit important evidence and weaken citation quality because the chat layer should retrieve from source content. - Option B: Keyword-only search can miss semantically relevant passages when users ask natural-language questions. - Option D: A larger chat model does not replace retrieval when users need grounded answers over a document corpus.

Sample Question 5 — Implement information extraction solutions

A support team upgraded to a larger language model for a document Q&A bot, but answers are still poorly grounded. Citations often point to irrelevant snippets, and some newly uploaded files never appear in answers. What should the team investigate first?

  1. A. Review extraction quality, chunk boundaries, metadata, and index freshness (Correct answer)
  2. B. Increase content filtering to block unsupported answers
  3. C. Fine-tune the chat model on prior conversations
  4. D. Replace Azure AI Search with a longer system prompt

Correct answer: A

Explanation: Correct answer (A): The symptoms point to retrieval-pipeline problems, not model size. Irrelevant citations usually indicate issues such as poor chunking or missing metadata, and newly uploaded files not appearing strongly suggests ingestion or index freshness problems. The best first step is to review extraction quality, chunk boundaries, metadata, and whether the search index is current. Why the other options are wrong: - Option B: Content filters address safety concerns, not retrieval relevance, stale content, or missing citations. - Option C: Fine-tuning is not the best first action when the likely root cause is in retrieval and indexing. - Option D: A longer system prompt does not fix bad extraction, poor chunking, missing metadata, or stale index content.

Sample Question 6 — Implement information extraction solutions

A bank uses document extraction to capture applicant income and ID values. Regulations require that uncertain results are not acted on automatically. What is the best pipeline behavior?

  1. A. Accept all extracted values and log them for later auditing
  2. B. Route low-confidence extractions to human review before approval decisions (Correct answer)
  3. C. Use a larger chat model to rewrite low-confidence fields more confidently
  4. D. Rely on content filters to prevent incorrect field values

Correct answer: B

Explanation: Correct answer (B): In a regulated workflow, uncertain extracted values should not drive automated decisions. The right design is to apply confidence thresholds and send low-confidence results to an exception or human-review path before making approval decisions. Logging, larger models, and content filters do not make uncertain extracted values trustworthy. Why the other options are wrong: - Option A: Logging helps with auditing, but it does not stop incorrect values from affecting regulated decisions. - Option C: A larger model does not make uncertain extracted values reliable enough for regulated automation. - Option D: Content filters are safety controls; they do not validate extraction accuracy for business fields.

Sample Question 7 — Implement information extraction solutions

An internal app extracts employee onboarding packets, stores normalized outputs in Azure Storage, and indexes searchable text in Azure AI Search. Security policy forbids secrets in source code and requires least-privilege access. Which authentication design is best?

  1. A. Store service keys in environment variables for the app
  2. B. Use a managed identity with RBAC on only the required resources (Correct answer)
  3. C. Put shared keys in a configuration file encrypted at rest
  4. D. Give the app contributor access to the whole subscription

Correct answer: B

Explanation: Correct answer (B): Managed identity with RBAC is the preferred Azure-native design because it avoids embedded secrets and supports least-privilege access. The app can be granted only the minimal permissions it needs on Azure Storage and Azure AI Search, which is especially important when extracted content contains sensitive employee data. Why the other options are wrong: - Option A: Environment variables still require secret management and are not preferred when managed identity is available. - Option C: Encryption at rest protects stored secrets, but the design still depends on managing secrets instead of using keyless Azure-native authentication. - Option D: Subscription-wide contributor access violates least-privilege guidance.

Sample Question 8 — Implement information extraction solutions

You're designing a regulated finance workflow that will both automate field capture and support grounded chat over approved documents. Which production sequence is best?

  1. A. Ingest content, summarize with a chat model, index the summaries, then extract fields if users complain
  2. B. Ingest content, extract text, structure, and fields, validate confidence, store normalized outputs, index searchable content, then enable grounded Q&A (Correct answer)
  3. C. Ingest content, send all raw files directly to the chat model, and let the model decide when validation is needed
  4. D. Ingest content, OCR everything, skip field validation, and rely on content filters before indexing

Correct answer: B

Explanation: Correct answer (B): A production extraction workflow should separate deterministic extraction from downstream conversational access. The strongest sequence is to ingest content, extract text, structure, and fields, validate low-confidence results, store normalized outputs, index approved searchable content, and only then enable grounded Q&A. Starting with summarization or raw chat skips validation and weakens both compliance and grounding. Why the other options are wrong: - Option A: Beginning with summarization reduces determinism and makes both field capture and grounded retrieval less reliable. - Option C: Sending raw files directly to a chat model skips structured extraction and validation, which is risky in a regulated workflow. - Option D: OCR alone does not provide normalized business fields, and content filters do not replace extraction validation.
