The answer for the second question is wrong. There will be no projection for normalized images. You have to remember object projection is for JSON document not binary raw images. Both projections don’t have the files specified.

I agree. it should be "source" and not "sourceContext" File projections are always binary, normalized images "source" key in JSON https://learn.microsoft.com/en-us/azure/search/knowledge-store-projections-examples#define-a-file-projection

I agree with you, for images you should define a file projection but there is none (https://learn.microsoft.com/en-us/azure/search/knowledge-store-projections-examples#define-a-table-projection)

Correct! https://learn.microsoft.com/en-us/azure/search/knowledge-store-projection-example-long#relationships-among-table-object-and-file-projections If you don't want the data related, define the projections in different projection groups. For example, the following snippet will result in the tables being related, but without relationships between the tables and the object (OCR text) projections. https://learn.microsoft.com/en-us/azure/search/knowledge-store-projections-examples#define-a-file-projection File projections are always binary, normalized images, where normalization refers to potential resizing and rotation for use in skillset execution. File projections, similar to object projections, are created as blobs in Azure Storage, and contain binary data (as opposed to JSON).

First one is correct - 2 Projection Groups. But for the 2nd one the JSON contains projections related to objects and tables, but no projection for files. Normalized images (/document/normalized_images/) are referenced within objects but are not stored in tables or files. Since files are empty ("files": []), the images won't be projected to Blob/File storage. I think it should be "Not be projected"

This is somewhat of a trick question. Its important to note that the term "normalized image" does not refer to the raw binary file of the image, but rather to the transformed version which includes only the text (referred to in the JSON as "/document/normalized_images/*/text"). Hence, the normalized image is in fact being stored to the BLOB storage as an object.

The code you provided contains two projection groups. Here they are: The first projection group includes the following tables: unrelatedDocument unrelatedKeyPhrases The second projection group includes the following objects: unrelatedocrtext unrelatedocrlayout

The correct answer is one projection group. In the provided JSON, there is one projections array, which means there is one projection group. The correct answer is be projected to Azure Blob storage. The storageContainer fields “unrelatedocrtext” and “unrelatedocrlayout” indicate that the normalized images (both text and layout text) are being stored in Azure Blob storage containers. Azure Table storage is not used in this scenario.
