- A
Index
Why wrong: An index is necessary to store the searchable results, but it is not one of the three pipeline components required for extraction and enrichment. The question asks for the components that extract and enrich, which are data source, skillset, and indexer.
- B
Skillset
Correct. A skillset defines the AI enrichment steps such as OCR, entity recognition, or language detection that transform the raw PDF content into enriched data.
- C
Semantic configuration
Why wrong: Incorrect. Semantic configuration is an optional feature for improving search relevance, not a required component for extraction and enrichment.
- D
Data source
Correct. A data source provides the connection information and credentials to access the PDF files stored in Azure Blob Storage or other locations.
- E
Indexer
Correct. An indexer orchestrates the pipeline by connecting the data source, applying the skillset, and loading the enriched content into the index.
AI-102 Practice Question: Implement knowledge mining and information extraction solutions
This AI-102 practice question tests your understanding of implement knowledge mining and information extraction solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE components are required to build a knowledge mining solution using Azure AI Search that extracts and enriches content from PDF files?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Skillset
To build a knowledge mining solution that extracts and enriches content from PDF files using Azure AI Search, three components are required: a data source (to connect to the PDFs), a skillset (to apply AI enrichment like OCR and entity extraction), and an indexer (to orchestrate the pipeline and ingest the enriched content into the index). While an index is also necessary to store the results, it is not considered a pipeline component in the same context, and the question asks for the three components of the extraction and enrichment pipeline.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often include the index as a required component or overlook the indexer. However, the three core pipeline components are data source, skillset, and indexer. The index is a separate entity that is created as part of the solution but is not one of the three pipeline components asked for.
Detailed technical explanation
How to think about this question
Under the hood, the indexer orchestrates the pipeline by pulling content from the data source, passing it through the skillset for AI enrichment (e.g., OCR, entity recognition), and then writing the output into the index. A real-world scenario is processing a batch of scanned PDF invoices where the data source points to Azure Blob Storage, the skillset extracts text via OCR and detects key fields, and the index stores the results for full-text search.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
