AI-102 Question 387
Select 3You are designing a Knowledge Store for an Azure Cognitive Search solution. The Knowledge Store will be used to analyze and structure data extracted from a set of unstructured documents. You need to configure projections to support different data exploration scenarios. Which projection types should you use to achieve this?
- A
File projection to store enriched content in its original format for downstream processing.
- B
Object projection to create structured JSON documents for data modeling and visualization.
- C
Table projection to store key-value pairs for use in relational database queries.
- D
File projection to convert data into relational database tables.
- E
Object projection to generate tabular data for use in Power BI.
Show answer and explanation
Correct answers: A, B, C
Explanation
Knowledge Store projections allow you to organize enriched data into different formats suitable for specific scenarios: file projections retain original formats for downstream processing, object projections create JSON documents for hierarchical data exploration, and table projections structure data into tabular formats for relational database use. Understanding these projection types is crucial for designing flexible and effective Knowledge Store solutions.
- A. Correct.
File projection is used to store enriched content, such as transformed or annotated data, in its original format. This is useful for downstream processing and reusability.
- B. Correct.
Object projection is used to create structured JSON documents, which are ideal for hierarchical data modeling and visualization in modern applications.
- C. Correct.
Table projection is used to create key-value pairs or tabular representations that can be directly queried or integrated with relational database systems.
- D. Incorrect.
File projection does not convert data into relational database tables; this is not its purpose.
- E. Incorrect.
Object projection does not generate tabular data; that is the purpose of table projections.
