Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point. A. The index size will increase. B. Query times will increase. C. A self-signed X.509 certificate is required. D. The index size will decrease. E. Query times will decrease. F. Azure Key Vault is required. Answer: ABF Explanation: A. The index size will increase. B. Query times will increase. F. Azure Key Vault is required https://docs.microsoft.com/en-us/azure/search/search-security-overview#customer-managed-keys-cmk Customer-managed keys (CMK) Customer-managed keys require an additional billable service, Azure Key Vault, which can be in a different region, but under the same subscription, as Azure Cognitive Search. Enabling CMK encryption will increase index size and degrade query performance. Based on observations to date, you can expect to see an increase of 30%-60% in query times, although actual performance will vary depending on the index definition and types of queries. Because of this performance impact, we recommend that you only enable this feature on indexes that really require it. Question: 13 You are developing a new sales system that will process the video and text from a public-facing website. You plan to notify users that their data has been processed by the sales system. CertyIQ Which responsible AI principle does this help meet? A. transparency B. fairness C. inclusiveness D. reliability and safety Answer: A Explanation: The correct answer is A, transparency: "When an AI application relies on personal data, such as a facial recognition system that takes images of people to recognize them; you should make it clear to the user how their data is used and retained, and who has access to it." from: https://docs.microsoft.com/en-us/learn/paths/prepare-for-ai-engineering/ Question: 14 CertyIQ Note: This question is part of a series of questions that present the same scenario.

Which Azure Cognitive Services API should you use? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. Hot Area: Answer: Explanation: Box1: https://eastus.api.cognitive.microsoft.com Box2: /text/analytics/v3.1/languages Reference: https://learn.microsoft.com/en-us/rest/api/cognitiveservices-textanalytics/3.0/languages/languages? tabs=HTTP. Question: 31 CertyIQ You have an Azure Cognitive Search instance that indexes purchase orders by using Form Recognizer. You need to analyze the extracted information by using Microsoft Power BI. The solution must minimize development effort. What should you add to the indexer? A. a projection group B. a table projection C. a file projection D. an object projection Answer: B Explanation: To analyze the extracted information from the Azure Cognitive Search index with Microsoft Power BI, you should add a table projection to the indexing. This will allow you to present the data in a tabular format that can be easily imported and analyzed by Power BI with minimal development effort. So, the correct answer is: B. a table projection Question: 32 CertyIQ Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You have an Azure Cognitive Search service. During the past 12 months, query volume steadily increased. You discover that some search query requests to the Cognitive Search service are being throttled. You need to reduce the likelihood that search query requests are throttled. Solution: You add replicas. Does this meet the goal? A. Yes B. No Answer: A Explanation: A is the answer. Quote "In Cognitive Search, replicas are copies of your index." at https://learn.microsoft.com/enus/azure/search/search-reliability https://learn.microsoft.com/en-us/azure/search/search-performance-analysis#throttling-behaviors Throttling occurs when the search service is at capacity. Throttling can occur during queries or indexing. From the client side, an API call results in a 503 HTTP response when it has been throttled. During indexing, there's also the possibility of receiving a 207 HTTP response, which indicates that one or more items failed to index. This error is an indicator that the search service is getting close to capacity. A simple fix to most throttling issues is to throw more resources at the search service (typically replicas for query-based throttling, or partitions for indexing-based throttling). However, increasing replicas or partitions adds cost, which is why it's important to know the reason why throttling is occurring at all. Investigating the conditions that cause throttling will be explained in the next several sections.

How should you configure the project in the Custom Vision portal? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. Hot Area: Answer: Explanation: Box 1: Classification Incorrect Answers: An object detection project is for detecting which objects, if any, from a set of candidates are present in an image. Box 2: Multiclass A multiclass classification project is for classifying images into a set of tags, or target labels. An image can be assigned to one tag only. Incorrect Answers: A multilabel classification project is similar, but each image can have multiple tags assigned to it. Box 3: General (compact) https://learn.microsoft.com/en-us/azure/cognitive-services/custom-vision-service/getting-started-build-aclassifier - Select Classification under Project Types. Then, under Classification Types, choose either Multilabel or Multiclass, depending on your use case. Multilabel classification applies any number of your tags to an image (zero or more), while multiclass classification sorts images into single categories (every image you submit will be sorted into the most likely tag). You'll be able to change the classification type later if you want to. Reference: https://cran.r-project.org/web/packages/AzureVision/vignettes/customvision.html Question: 69 CertyIQ You have an Azure Video Analyzer for Media (previously 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? A. Create a person model and associate the model to the videos. B. Create person objects and provide face images for each object. C. Invite the entire staff of the company to Video Indexer. D. Edit the faces in the videos. E. Upload names to a language model. Answer: A Explanation: 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: 70 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. NOTE: Each correct selection is worth one point. A. recall B. F-score C. weighted accuracy D. precision E. area under the curve (AUC) Answer: AD Explanation: CertyIQ Custom Vision provides three metrics regarding the performance of your model: precision, recall, and AP. https://learn.microsoft.com/en-us/azure/cognitive-services/custom-vision-service/getting-started-build-aclassifier#evaluate-the-classifier After training has completed, the model's performance is estimated and displayed. The Custom Vision Service uses the images that you submitted for training to calculate precision and recall. Precision and recall are two different measurements of the effectiveness of a classifier: - Precision indicates the fraction of identified classifications that were correct. For example, if the model identified 100 images as dogs, and 99 of them were actually of dogs, then the precision would be 99%. - Recall indicates the fraction of actual classifications that were correctly identified. For example, if there were actually 100 images of apples, and the model identified 80 as apples, the recall would be 80%. Reference: https://www.tallan.com/blog/2020/05/19/azure-custom-vision/ Question: 71 CertyIQ DRAG DROP You are developing a call to the Face API. The call must find similar faces from an existing list named employeefaces. The employeefaces list contains 60,000 images. How should you complete the body of the HTTP request? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point. Select and Place: Answer: Explanation: Box 1: LargeFaceListID LargeFaceList: Add a face to a specified large face list, up to 1,000,000 faces. Note: Given query face's faceId, to search the similar-looking faces from a faceId array, a face list or a large face list. A "faceListId" is created by FaceList - Create containing persistedFaceIds that will not expire. And a "largeFaceListId" is created by LargeFaceList - Create containing persistedFaceIds that will also not expire. Incorrect Answers: Not "faceListId": Add a face to a specified face list, up to 1,000 faces. Box 2: matchFace Find similar has two working modes, "matchPerson" and "matchFace". "matchPerson" is the default mode that it tries to find faces of the same person as possible by using internal same-person thresholds. It is useful to find a known person's other photos. Note that an empty list will be returned if no faces pass the internal thresholds. "matchFace" mode ignores same-person thresholds and returns ranked similar faces anyway, even the similarity is low. It can be used in the cases like searching celebrity-looking faces.

The method to detect the faces uses the following code. You discover that the solution frequently fails to detect faces in blurred images and in images that contain sideways faces. You need to increase the likelihood that the solution can detect faces in blurred images and images that contain sideways faces. What should you do? A. Use a different version of the Face API. B. Use the Computer Vision service instead of the Face service. C. Use the Identify method instead of the Detect method. D. Change the detection model. Answer: D Explanation: Evaluate different models. The best way to compare the performances of the detection models is to use them on a sample dataset. We recommend calling the Face - Detect API on a variety of images, especially images of many faces or of faces that are difficult to see, using each detection model. Pay attention to the number of faces that each model returns. The different face detection models are optimized for different tasks. See the following table for an overview of the differences. Reference: https://docs.microsoft.com/en-us/azure/cognitive-services/face/face-api-how-to-topics/specify-detection-mo del Question: 76 CertyIQ You have the following Python function for creating Azure Cognitive Services resources programmatically. def create_resource (resource_name, kind, account_tier, location) : parameters = CognitiveServicesAccount(sku=Sku(name=account_tier), kind=kind, location=location, properties= ) result = client.accounts.create(resource_group_name, resource_name, parameters) You need to call the function to create a free Azure resource in the West US Azure region. The resource will be used to generate captions of images automatically. Which code should you use? A. create_resource("res1", "ComputerVision", "F0", "westus") B. create_resource("res1", "CustomVision.Prediction", "F0", "westus") C. create_resource("res1", "ComputerVision", "S0", "westus") D. create_resource("res1", "CustomVision.Prediction", "S0", "westus") Answer: A Explanation: A is the answer. https://learn.microsoft.com/en-us/azure/cognitive-services/cognitive-services-apis-create-account-clientlibrary?pivots=programming-language-python#create-a-cognitive-services-resource-python To create and subscribe to a new Cognitive Services resource, use the Create function. This function adds a new billable resource to the resource group you pass in. When you create your new resource, you'll need to know the "kind" of service you want to use, along with its pricing tier (or SKU) and an Azure location. The following function takes all of these arguments and creates a resource. Question: 77 CertyIQ 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. A. Remove the operation_id parameter. B. Add code to verify the read_results.status value. C. Add code to verify the status of the read_operation_location value. D. Wrap the call to get_read_result within a loop that contains a delay. Answer: BD Explanation: B. Add code to verify the read_results.status value. D. Wrap the call to get_read_result within a loop that contains a delay. Explanation: In order to prevent the GetReadResultAsync method from proceeding until the read operation is complete, we need to check the status of the read operation and wait until it's completed. To do this, we can add code to verify the status of the read_results.status value. If the status is not "succeeded", we can add a delay and then retry the operation until it's complete. This can be achieved by wrapping the call to get_read_result within a loop that contains a delay. Removing the operation_id parameter or adding code to verify the status of the read_operation_location value will not solve the issue of waiting for the read operation to complete before proceeding with the GetReadResultAsync method. Question: 78 CertyIQ HOTSPOT You are building an app that will enable users to upload images. The solution must meet the following requirements: * Automatically suggest alt text for the images. * Detect inappropriate images and block them. * Minimize development effort.
