AZ-305 · Question 29 · Domain 2.4: Non-relational data storage

A legal firm has 2 million scanned PDF documents stored in Azure Blob Storage. These documents contain contracts, court filings, and evidence.

Lawyers need a web portal to search for specific clauses, names, and organizations across all documents. Because the documents are scanned images, the text must be extracted automatically during the indexing process. Additionally, the solution must automatically identify and tag the names of people and organizations found in the text.

Which Azure service should you recommend?

Answer options:

A.

Azure Synapse Analytics

B.

Azure Cognitive Search with AI enrichment

C.

Azure Cosmos DB SQL API

D.

Azure Machine Learning

How to approach this question

Look for the service that combines full-text search indexing with built-in AI capabilities (OCR, Entity Recognition).

Full Answer

B.Azure Cognitive Search with AI enrichment✓ Correct
Azure Cognitive Search (now Azure AI Search) is the only Azure service designed specifically for full-text search over unstructured data. By configuring an AI enrichment pipeline (skillsets), it can automatically apply Optical Character Recognition (OCR) to scanned images/PDFs to extract text, and apply Natural Language Processing (NLP) to extract entities like people, locations, and organizations.

Common mistakes

Thinking you need to build a custom Machine Learning pipeline. Cognitive Search has these AI skills built-in.
