Microsoft Microsoft Certifications AI-100 Questions & Answers

• Question 91:

  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, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

  You need to create an IoT solution that performs the following tasks:

  1.

  Identifies hazards

  2.

  Provides a real-time online dashboard

  3.

  Takes images of an area every minute

  4.

  Counts the number of people in an area every minute

  Solution: You configure the IoT devices to send the images to an Azure IoT hub, and then you configure an Azure Functions call to Azure Cognitive Services that sends the results to an Azure event hub. You configure Microsoft Power BI to

  connect to the event hub by using Azure Stream Analytics.

  Does this meet the goal?

  A. Yes

  B. No

  Correct Answer: B

  Instead use Cognitive Services containers on the IoT devices.

• Question 93:

  You plan to deploy Azure IoT Edge devices. Each device will store more than 10,000 images locally. Each image is approximately 5 MB.

  You need to ensure that the images persist on the devices for 14 days.

  What should you use?

  A. Azure Stream Analytics on the IoT Edge devices

  B. Azure Database for Postgres SQL

  C. Azure Blob storage on the IoT Edge devices

  D. Microsoft SQL Server on the IoT Edge devices

  Correct Answer: C

  Azure Blob Storage on IoT Edge provides a block blob and append blob storage solution at the edge. A blob storage module on your IoT Edge device behaves like an Azure blob service, except the blobs are stored locally on your IoT Edge

  device.

  This e is useful where data needs to be stored locally until it can be processed or transferred to the cloud. This data can be videos, images, finance data, hospital data, or any other unstructured data.

• Question 94:

  You have an Azure Machine Learning experiment.

  You need to validate that the experiment meets GDPR regulation requirements and stores documentation about the experiment.

  What should you use?

  A. Compliance Manager

  B. an Azure Log Analytics workspace

  C. Azure Table storage

  D. Azure Security Center

  Correct Answer: A

  Compliance Manager for Azure helps you assess and manage GDPR compliance. Compliance Manager is a free, Microsoft cloud services solution designed to help organizations meet complex compliance obligations, including the GDPR, ISO 27001, ISO 27018, and NIST 800-53. Generally available today for Azure customers, the Compliance Manager GDPR dashboard enables you to assign, track, and record your GDPR compliance activities so you can collaborate across teams and manage your documents for creating audit reports more easily.

• Question 95:

  You are designing a solution that will integrate the Bing Web Search API and will return a JSON response. The development team at your company uses C# as its primary development language.

  You provide developers with the Bing endpoint.

  Which additional component do the developers need to prepare and to retrieve data by using an API call?

  A. the subscription ID

  B. the API key

  C. a query

  D. the resource group ID

  Correct Answer: C

  The Bing Web Search SDK makes it easy to integrate Bing Web Search into your C# application. You instantiate a client, send a request, and receive a response.

• Question 96:

  You have an app that records meetings by using speech-to-text capabilities from the Speech Services API.

  You discover that when action items are listed at the end of each meeting, the app transcribes the text inaccurately.

  You need to improve the accuracy of the meeting records.

  What should you do?

  A. Add a phrase list

  B. Create a custom wake word

  C. Parse the text by using the Language Understanding (LUIS) API

  D. Train a custom model by using Custom Translator

  Correct Answer: D

  Speech Services API with subscribtion to the Microsoft Text Translation API enables you to use Custom Translator to use your own data for more accurate translations.

• Question 97:

  You need to create a new app that will consume resources from the following Azure Cognitive Services APIs:

  1.

  Face API

  2.

  Bing Search

  3.

  Text Analytics

  4.

  Translator Text

  5.

  Language Understanding (LUIS)

  The solution must prepare the development environment as quickly as possible.

  B. a Cognitive Services resource

  C. an Azure Kubernetes Service (AKS) resource

  D. Face and Language Understanding (LUIS) resources

  Correct Answer: B

  After creating a Cognitive Service resource in the Azure portal, you'll get an endpoint and a key for authenticating your applications. Create a new Azure Cognitive Services resource

  Which tool should you use?

  A. the .NET Core CLI

  B. the Azure CLI

  C. the Git CLI

  D. the AzCopy toll

  Correct Answer: B

  The deployment process documented here uses one of the ARM templates to provision required resources for the bot in Azure by using the Azure CLI.

  Note: When you create a bot using the Visual Studio template, Yeoman template, or Cookiecutter template the source code generated includes a deploymentTemplates folder that contains ARM templates.

  https://docs.microsoft.com/en-us/azure/bot-service/bot-builder-deploy-az-cli

• Question 99:

  You have an existing Language Understanding (LUIS) model for an internal bot.

  Which component of LUIS should you recommend?

  A. domain

  B. intents

  C. entities

  Correct Answer: C

  LUIS includes a set of prebuilt entities for recognizing common types of information, like dates, times, numbers, measurements, and currency. Prebuilt entity support varies by the culture of your LUIS app.

  Note: LUIS provides three types of prebuilt models. Each model can be added to your app at any time.

  Model type: Includes

  1.

  Domain: Intents, utterances, entities

  2.

  Intents: Intents, utterances

  3.

  Entities: Entities only
