Question 2

You are managing a multi-tenant SaaS application that uses Azure AI Vision. Each tenant has their own isolated data, and you want to track costs per tenant. How should you provision Azure AI services to achieve granular cost attribution?

Accepted Answer

Deploy a dedicated Azure AI Services resource per tenant and use Azure Cost Management for billing attribution.. Provisioning separate Azure AI Services resources per tenant (or using resource tags with Azure Cost Management) allows granular cost tracking, though separate resources provide strict billing isolation.

Answer

Use a single global Azure AI Services resource and parse tenant IDs from request user-agent headers for billing.

Answer

Store tenant IDs in Custom Vision project tags.

Answer

Use Azure Blob Storage cost allocation tags to cover AI API costs.

Question 3

Answer

Store API keys in plain text configuration files on public GitHub repositories.

Answer

Disable TLS encryption to improve API response latency.

Question 6

You are preparing training images for a Custom Vision object detection project. Which THREE data preparation practices should you follow to ensure high model accuracy? (Choose three.)

Accepted Answer

Vary object angles, lighting, and scale across your training images.. Good practices for Custom Vision include providing variety in backgrounds, ensuring multiple instances of objects across different angles and lighting, and meeting minimum tag counts.

Answer

Use identical background images for all training samples to maintain consistency.

Answer

Keep all training images under 100x100 pixels to speed up training.

Question 7

You are troubleshooting a Custom Vision object detection model that exhibits poor performance in production. Which THREE actions can you take using the Custom Vision portal or APIs to diagnose and improve the model? (Choose three.)

Accepted Answer

Examine prediction suggestions to find low-confidence or incorrectly predicted images and add them to training data.. Portal diagnostics include reviewing prediction performance metrics (Precision, Recall, mAP), tagging missed detections (Smart Labeling / Suggested Tags), and adjusting probability thresholds.

Answer

Delete all project iteration history to reset model weights to random initialization.

Answer

Manually edit model neural network weights via the REST API.

Question 8

You are developing a .NET application that interacts with Azure AI Vision Read API. Which TWO objects or properties would you inspect in the asynchronous response to retrieve extracted text lines and their confidence scores? (Choose two.)

Accepted Answer

text. The Read API response contains `analyzeResult.readResults` or `readResult.blocks`/`lines`, where each line has `text`, `boundingBox`, and `confidence` (in older versions) or text content.

Answer

dominantColors

Answer

adultScore

Answer

smartCrops

Question 9

Which TWO image file formats are natively supported by Azure AI Vision for image analysis? (Choose two.)

Accepted Answer

JPEG. Azure AI Vision supports standard web formats including JPEG, PNG, GIF, BMP, WEBP, and TIFF (for Read).

Answer

MP3

Answer

MKV

Answer

WAV

Question 10

You are deploying Custom Vision containers on-premises using Docker. Which THREE prerequisites and configuration steps are required? (Choose three.)

Accepted Answer

Ensure internet connectivity or periodic connection to Azure for billing metering.. Custom Vision containers require an Azure AI Services or Custom Vision billing endpoint/key, acceptance of the EULA, and proper Docker runtime environment variables.

Answer

Install the full Azure CLI inside every prediction container.

Answer

Grant root access to the Azure subscription billing portal from inside the container.

Question 11

When designing an automated document processing pipeline using Azure AI Vision Read API, which THREE architectural considerations should you account for? (Choose three.)

Accepted Answer

Ensure document files adhere to supported page count and file size limits.. Read API is asynchronous, returns HTTP 202, requires polling the Operation-Location URL, and processes documents page-by-page or up to supported multi-page limits.

Answer

Expect synchronous JSON responses containing all extracted text directly on the initial POST call.

Answer

Configure the API to store extracted text permanently in local memory without pagination.

Question 12

You are creating a Custom Vision project and need to select a domain. Your project involves classifying images of various food dishes. Which domain should you select to optimize model accuracy for food classification?

Question 13

You need to extract text from a multi-page PDF document using Azure AI Vision Read API. How are pages represented in the JSON response structure?

Accepted Answer

They are organized under a 'readResult.pages' or 'pages' array in the analyze result.. The Read API output organizes results by pages, where each page object contains dimensions, language, lines, and words.

Answer

All text from all pages is merged into a single unstructured string without page separation.

Answer

Pages are returned as separate JPEG files in a ZIP archive.

Answer

Each page requires a separate API transaction starting with a new POST request.

Question 14

Your enterprise application uses Azure AI Vision. Security policies require that all API keys are rotated every 30 days without causing application downtime. How should you manage the key rotation?
