Question 53
DRAG DROP - You are building an app that will scan confidential documents and use the Language service to analyze the contents. You provision an Azure Cognitive Services resource. You need to ensure that the app can make requests to the Language service endpoint. The solution must ensure that confidential documents remain on-premises. Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Question 54
HOTSPOT - You have an Azure subscription that has the following configurations: • Subscription ID: 8d3591aa-96b8-4737-ad09-00f9b1ed35ad • Tenant ID: 3edfe572-cb54-3ced-ae12-c5c177f39a12 You plan to create a resource that will perform sentiment analysis and optical character recognition (OCR). You need to use an HTTP request to create the resource in the subscription. The solution must use a single key and endpoint. How should you complete the request? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
Question 55
You have an Azure subscription that contains an Anomaly Detector resource. You deploy a Docker host server named Server1 to the on-premises network. You need to host an instance of the Anomaly Detector service on Server1. Which parameter should you include in the docker run command?
Question 56
You are building an app that will use the Speech service. You need to ensure that the app can authenticate to the service by using a Microsoft Azure Active Directory (Azure AD), part of Microsoft Entra, token. Which two actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.
Question 57
HOTSPOT - You are developing an application that will use the Computer Vision client library. The application has the following code. For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point. Hot Area:
Box 1: No - Box 2: Yes - The ComputerVision.analyzeImageInStreamAsync operation extracts a rich set of visual features based on the image content. Box 3: No - Images will be read from a stream.

Question 58
You have a Video Indexer service that is used to provide a search interface over company videos on your company's website. You need to be able to search for videos based on who is present in the video. What should you do?
Video Indexer supports multiple Person models per account. Once a model is created, you can use it by providing the model ID of a specific Person model when uploading/indexing or reindexing a video. Training a new face for a video updates the specific custom model that the video was associated with. Note: Video Indexer supports face detection and celebrity recognition for video content. The celebrity recognition feature covers about one million faces based on commonly requested data source such as IMDB, Wikipedia, and top LinkedIn influencers. Faces that aren't recognized by the celebrity recognition feature are detected but left unnamed. Once you label a face with a name, the face and name get added to your account's Person model. Video Indexer will then recognize this face in your future videos and past videos. Reference: https://docs.microsoft.com/en-us/azure/media-services/video-indexer/customize-person-model-with-api
Question 59
You use the Custom Vision service to build a classifier. After training is complete, you need to evaluate the classifier. Which two metrics are available for review? Each correct answer presents a complete solution. (Choose two.) NOTE: Each correct selection is worth one point.
Custom Vision provides three metrics regarding the performance of your model: precision, recall, and AP. Reference: https://www.tallan.com/blog/2020/05/19/azure-custom-vision/
Question 60
You are developing a method that uses the Computer Vision client library. The method will perform optical character recognition (OCR) in images. The method has the following code. During testing, you discover that the call to the GetReadResultAsync method occurs before the read operation is complete. You need to prevent the GetReadResultAsync method from proceeding until the read operation is complete. Which two actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.
Example code : do { results = await client.GetReadResultAsync(Guid.Parse(operationId)); } while ((results.Status == OperationStatusCodes.Running || results.Status == OperationStatusCodes.NotStarted)); Reference: https://github.com/Azure-Samples/cognitive-services-quickstart-code/blob/master/dotnet/ComputerVision/ComputerVisionQuickstart.cs
