B. Randomly split the data into rows for training and rows for evaluation.

C. Use labels for training and features for evaluation.

D. Randomly split the data into columns for training and columns for evaluation.

Question 3:


You build a machine learning model by using the automated machine learning user interface (UI). You need to ensure that the model meets the Microsoft transparency principle for responsible AI. What should you do?

A. Set Validation type to Auto.

B. Enable Explain the best model.

C. Set Primary metric to accuracy.

D. Set Max concurrent iterations to 0.


Correct Answer: B

Model Explain Ability.

Most businesses run on trust and being able to open the ML “black box” helps build transparency and trust. In heavily regulated industries like healthcare and banking, it is critical to comply with regulations and best practices. One key aspect

of this is understanding the relationship between input variables (features) and model output. Knowing both the magnitude and direction of the impact each feature (feature importance) has on the predicted value helps better understand and

explain the model. With model explainability, we enable you to understand feature importance as part of automated ML runs.



Question 4:


You are designing an AI system that empowers everyone, including people who have hearing, visual, and other impairments. This is an example of which Microsoft guiding principle for responsible AI.

A. fairness

B. inclusiveness

C. reliability and safety

D. accountability


Correct Answer: B

Inclusiveness: At Microsoft, we firmly believe everyone should benefit from intelligent technology, meaning it must incorporate and address a broad range of human needs and experiences. For the 1 billion people with disabilities around the world, AI technologies can be a game-changer.

A. Ensure that all visuals have an associated text that can be read by a screen reader.

B. Enable autoscaling to ensure that a service scales based on demand.

C. Provide documentation to help developers debug code.

D. Ensure that a training dataset is representative of the population.


Correct Answer: C

Question 6:


Your company is exploring the use of voice recognition technologies in its smart home devices. The company wants to identify any barriers that might unintentionally leave out specific user groups. This an example of which Microsoft guiding principle for responsible AI?

A. accountability

B. fairness

C. inclusiveness

D. privacy and security


Correct Answer: C



AI systems should empower everyone and engage people. AI should bring benefits to all parts of society, regardless of physical ability, gender, sexual orientation, ethnicity, or other factors.


Question 7:


What are three Microsoft guiding principles for responsible AI? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

A. knowledgeability

B. decisiveness

C. inclusiveness

D. fairness

E. opinionatedness

F. reliability and safety


Correct Answer: CDF

Question 8:


You run a charity event that involves posting photos of people wearing sunglasses on Twitter. You need to ensure that you only retweet photos that meet the following requirements:


Include one or more faces.


Contain at least one person wearing sunglasses. What should you use to analyze the images?

A. the Verify operation in the Face service

B. the Detect operation in the Face service

C. Describe Image operation in the Computer Vision service

D. the Analyze Image operation in the Computer Vision service


Correct Answer: B

Reference: https://docs.microsoft.com/en-us/azure/cognitive-services/face/overview

Question 9:


Which metric can you use to evaluate a classification model?

A. true positive rate

B. mean absolute error (MAE)

C. coefficient of determination (R2)

D. root mean squared error (RMSE)


Correct Answer: A

What does a good model look like?

A ROC curve that approaches the top left corner with a 100% true positive rate and 0% false positive rate will be the best model. A random model would display a flat line from the bottom left to the top right corner. Worse than random

would dip below the y=x line.



Question 10:


Which two components can you drag onto a canvas in Azure Machine Learning designer? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

A. dataset

B. compute

C. pipeline

D. module


Correct Answer: AD

You can drag and drop datasets and modules onto the canvas.

Reference: https://docs.microsoft.com/en-us/azure/machine-learning/concept-designer

Question 11:


You need to create a training dataset and validation dataset from an existing dataset. Which module in the Azure Machine Learning Designer should you use?

A. Select Columns in the Dataset

B. Add Rows

C. Split Data

D. Join Data


Correct Answer: C

A common way of evaluating a model is to divide the data into a training and test set by using Split Data, and then validate the model on the training data. Use the Split Data module to divide a dataset into two distinct sets. The studio currently supports training/validation data splits

Question 12:


You have the Predicted vs. True chart shown in the following exhibit.

AI-900 dumps practice questions 12

Which type of model is the chart used to evaluate?

A. classification

B. regression

C. clustering


Correct Answer: B

What is a Predicted vs. True chart?

Predicted vs. True shows the relationship between a predicted value and its correlating true value for a regression problem. This graph can be used to measure the performance of a model as the closer to the y=x line the predicted values are, the

better the accuracy of a predictive model.



Question 13:


Which type of machine learning should you use to predict the number of gift cards that will be sold next month?

A. classification

B. regression

C. clustering


Correct Answer: B

Clustering, in machine learning, is a method of grouping data points into similar clusters. It is also called segmentation.

Over the years, many clustering algorithms have been developed. Almost all clustering algorithms use the features of individual items to find similar items. For example, you might apply clustering to find similar people by demographics. You

might use clustering with text analysis to group sentences with similar topics or sentiments.



Question 14:


You have a dataset that contains information about taxi journeys that occurred during a given period.

You need to train a model to predict the fare of a taxi journey.

What should you use as a feature?

A. the number of taxi journeys in the dataset

B. the trip distance of individual taxi journeys

C. the fare of individual taxi journeys

D. the trip ID of individual taxi journeys


Correct Answer: B

The label is the column you want to predict. The identified features are the inputs you give the model to predict the Label.


The provided data set contains the following columns:

vendor_id: The ID of the taxi vendor is a feature.

rate_code: The rate type of the taxi trip is a feature.

passenger_count: The number of passengers on the trip is a feature. trip_time_in_secs: The amount of time the trip took. You want to predict the fare of the trip before the trip is completed. At that moment, you don’t know how long the trip

would take. Thus, the trip time is not a feature and you\’ll exclude this column from the model.

trip_distance: The distance of the trip is a feature.

payment_type: The payment method (cash or credit card) is a feature.

fare_amount: The total taxi fare paid is the label.



Question 15:


You need to predict the sea level in meters for the next 10 years. Which type of machine learning should you use?

A. classification

B. regression

C. clustering


Correct Answer: B

In the most basic sense, regression refers to the prediction of a numeric target.

Linear regression attempts to establish a linear relationship between one or more independent variables and a numeric outcome, or dependent variable.

You use this module to define a linear regression method, and then train a model using a labeled dataset.

The trained model can then be used to make predictions.
