  C. retrievable, filterable, and sortable

  D. retrievable, facetable, and key

  Correct Answer: B

  Retrievable: Include the category field in the search results.

  Searchable: Ensure that users can search for words in the category field.

  Facetable: Ensure that users can perform drill down filtering based on category.

• Question 2:

  You are building an AI solution that will use Sentiment Analysis results from surveys to calculate bonuses for customer service staff.

  You need to ensure that the solution meets the Microsoft responsible AI principles.

  What should you do?

  A. Add a human review and approval step before making decisions that affect the staff's financial situation.

  B. Include the Sentiment Analysis results when surveys return a low confidence score.

  C. Use all the surveys, including surveys by customers who requested that their account be deleted and their data be removed.

  D. Publish the raw survey data to a central location and provide the staff with access to the location.

  Correct Answer: A

• Question 3:

  You are building a solution that will detect anomalies in sensor data from the previous 24 hours. You need to ensure that the solution scans the entire dataset, at the same time, for anomalies. Which type of detection should you use?

  A. batch

  B. streaming

  C. change points

  Correct Answer: A

  https://learn.microsoft.com/en-us/azure/cognitive-services/anomaly-detector/overview#univariate-anomaly-detection Batch detection Use your time series to detect any anomalies that might exist throughout your data. This operation generates a model using your entire time series data, with each point analyzed with the same model.

• Question 4:

  You have an Azure subscription that contains a Language service resource named ta1 and a virtual network named vnet1. You need to ensure that only resources in vnet1 can access ta1.

  What should you configure?

  A. a network security group (NSG) for vnet1

  B. Azure Firewall for vnet1

  C. the virtual network settings for ta 1

  D. a Language service container for ta1

  Correct Answer: C

• Question 5:

  You are building a chatbot by using Microsoft Bot Framework Composer.

  You need to configure the chatbot to present a list of available options. The solution must ensure that an image is provided for each option.

  Which two features should you use? Each correct answer presents part of the solution.

  NOTE: Each correct selection is worth one point.

  A. an Azure function

  B. an adaptive card

  C. an entity

  D. a dialog

  E. an utterance

  Correct Answer: BD

• Question 6:

  You have an app that analyzes images by using the Computer Vision API.

  You need to configure the app to provide an output for users who are vision impaired. The solution must provide the output in complete sentences.

  Which API call should you perform?

  A. readInStreamAsync

  B. describelmagelnStreamAsync

  C. toglfiagelnStreaaAsync

  D. analyreImageByDomainInStreamAsync

  Correct Answer: B

• Question 7:

  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

  Correct Answer: A

  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

  is important to know the reason why throttling is occurring at all.

• Question 8:

  You are designing a conversational interface for an app that will be used to make vacation requests. The interface must gather the following data:

  1.

  The start date of a vacation

  2.

  The end date of a vacation

  3.

  The amount of required paid time off The solution must minimize dialog complexity. Which type of dialog should you use?

  A. Skill

  B. waterfall

  C. adaptive

  D. component

  Correct Answer: B

• Question 9:

  You are developing a monitoring system that will analyze engine sensor data, such as rotation speed, angle, temperature, and pressure. The system must generate an alert in response to atypical values. What should you include in the solution?

  A. Application Insights in Azure Monitor

  B. metric alerts in Azure Monitor

  C. Multivariate Anomaly Detection

  D. Univariate Anomaly Detection

  Correct Answer: C

  C is the answer.

  https://learn.microsoft.com/en-us/azure/cognitive-services/anomaly-detector/overview#multivariate-anomaly-detection The Multivariate Anomaly Detection APIs further enable developers by easily integrating advanced AI for detecting anomalies from groups of metrics, without the need for machine learning knowledge or labeled data. Dependencies and inter-correlations between up to 300 different signals are now automatically counted as key factors. This new capability helps you to proactively protect your complex systems such as software applications, servers, factory machines, spacecraft, or even your business, from failures.

• Question 10:

  You have an Azure subscription that contains an Anomaly Detector resource.
