The answer is to create a data source that connects to Azure Blob Storage. This is the correct first step because Azure Cognitive Search requires a configured data source object to define the connection string, container, and metadata for the PDFs before any indexing can occur. Without this foundational link, neither an indexer nor a skillset can access the blob content. On the AI-102 exam, this question tests your understanding of the ingestion pipeline order: data source first, then index, then indexer. A common trap is jumping straight to creating an indexer, but the indexer depends on an existing data source to pull documents. Remember the mnemonic "DSI" (Data Source first, then Index, then Indexer) to lock in the correct sequence for indexing PDFs from Azure Blob Storage.
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.
Your company has a large set of PDF documents stored in Azure Blob Storage. You need to index these documents in Azure Cognitive Search so that users can search the text content. What is the first step you should take?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a data source that connects to Azure Blob Storage.
Option A is correct because you need to create a data source that points to the Blob Storage container to fetch the documents. Option B is wrong because you need a data source before creating an indexer. Option C is wrong because the indexer will create the index based on the data source. Option D is wrong because the indexer will handle skillset execution.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Create an index with a field for each metadata property.
Why it's wrong here
The index can be created after or by the indexer, but data source comes first.
✗
Create a skillset to extract text from PDFs.
Why it's wrong here
Skillset is optional and not the first step.
✓
Create a data source that connects to Azure Blob Storage.
Why this is correct
A data source is required to specify where the data is located.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Create an indexer that runs daily.
Why it's wrong here
An indexer requires a data source to be created first.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
