AI-103 Quick Quiz — 10 Questions

Question 1

Your enterprise application uses Custom Vision. Due to compliance policies, you must ensure that your training data and model endpoints reside within a specific Azure region with strict data residency guarantees. Which resource configuration should you use?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Create a Custom Vision training and prediction resource in the targeted Azure region.. Custom Vision resources must be created in an Azure region that supports Custom Vision, and data remains within that region. Using a Cognitive Services multi-service resource or regional Custom Vision resource ensures regional residency.

Answer

Use the Global resource endpoint for Custom Vision.

Answer

Use Azure AI Vision multi-service account with global routing.

Answer

Store images in Azure Blob Storage with geo-replication.

Question 2

You are designing a multimodal solution that combines Azure AI Vision dense captions with Azure OpenAI GPT-4 Vision. You want to extract precise bounding box coordinates for multiple objects in complex scenes and pass them as structured context. Which API feature should you invoke?

Accepted Answer

features=denseCaptions. Dense captions return a set of regional bounding boxes and corresponding descriptive text snippets.

Answer

features=objects

Answer

features=smartCrops

Answer

features=tags

Question 3

Your application uploads images to Azure AI Vision via URLs. One of your URLs is failing with an invalid image error, even though the image opens correctly in web browsers. What is the most likely reason?

Accepted Answer

The URL requires HTTP Basic Authentication or redirects that the vision service cannot resolve.. Azure AI Vision must be able to publicly access the URL without authentication barriers (like cookies, redirects, or private IP spaces).

Answer

Azure AI Vision does not support URL-based inputs; you must upload binary bytes.

Answer

The image file size exceeds 500 MB.

Answer

Image URLs are restricted to PNG format only.

Question 4

You are using Azure AI Vision Read API in your application. You want to ensure that the extracted text blocks return word-level bounding polygons rather than just line-level bounding boxes. What parameter or response structure should you examine?

Accepted Answer

Examine the 'words' array within each returned 'lines' object in the JSON response payload.. The Read API response structure automatically includes word-level details inside each line object (`lines[*].words[*]`), providing bounding polygons for both lines and individual words.

Answer

Add ?wordLevel=true to the query string.

Answer

Call the legacy OCR endpoint instead.

Answer

Set the model-version parameter to v2.0.

Question 5

Your company wants to generate descriptive captions for thousands of product images automatically using Azure AI Vision. Which visual feature parameter should you specify in the analyze request?

Accepted Answer

features=caption. The 'captions' visual feature extracts a human-readable sentence describing the image content.

Answer

features=read

Answer

features=smartCrops

Answer

features=objects

Question 6

You are using Azure AI Vision 4.0. You want to obtain a concise, single-sentence human-readable description of an image. Which feature parameter should you request?

Accepted Answer

features=caption. The 'caption' feature returns a single descriptive sentence about the image content.

Answer

features=tags

Answer

features=denseCaptions

Answer

features=read

Question 7

You are building an agent using Azure AI Agent Service that needs to maintain long-term conversational memory across multiple sessions with a user. Which feature should you utilize to store and retrieve past user interactions?

Accepted Answer

Answer

Recall only

Answer

Precision only

Answer

Model ID

Question 10

Which TWO metrics are reported by Document Intelligence Studio to evaluate model performance?

Accepted Answer

Recall. Precision and Recall are the core metrics provided for every field in a custom model.

Answer
