A. Bulk Insert SQL Query
B. AzCopy
C. Python script
D. Azure Storage Explorer
E. Bulk Copy Program (BCP)
You are building a regression model tot estimating the number of calls during an event.You need to determine whether the feature values achieve the conditions to build aPoisson regression model.Which two conditions must the feature set contain? I ach correct answer presents part ofthe solution. NOTE: Each correct selection is worth one point.
A. The label data must be a negative value.
B. The label data can be positive or negative,
C. The label data must be a positive value
D. The label data must be non discrete.
E. The data must be whole numbers.
You are determining if two sets of data are significantly different from one another by usingAzure Machine Learning Studio.Estimated values in one set of data may be more than or less than reference values in theother set of data. You must produce a distribution that has a constant Type I error as afunction of the correlation.You need to produce the distribution.Which type of distribution should you produce?
A. Paired t-test with a two-tail option
B. Unpaired t-test with a two tail option
C. Paired t-test with a one-tail option
D. Unpaired t-test with a one-tail option
You are performing a filter based feature selection for a dataset 10 build a multi classclassifies by using Azure Machine Learning Studio.The dataset contains categorical features that are highly correlated to the output label column.You need to select the appropriate feature scoring statistical method to identify the keypredictors. Which method should you use?
A. Chi-squared
B. Spearman correlation
C. Kendall correlation
D. Person correlation
Note: This question is part of a series of questions that present the same scenario. Eachquestion in the series contains a unique solution that might meet the stated goals. Somequestion 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 are creating a new experiment in Azure Machine Learning Studio.One class has a much smaller number of observations than the other classes in the training set.You need to select an appropriate data sampling strategy to compensate for the class imbalance.Solution: You use the Scale and Reduce sampling mode.Does the solution meet the goal?
A. Yes
B. No
You plan to use a Deep Learning Virtual Machine (DLVM) to train deep learning modelsusing Compute Unified Device Architecture (CUDA) computations.You need to configure the DLVM to support CUDA.What should you implement?
A. Intel Software Guard Extensions (Intel SGX) technology
B. Solid State Drives (SSD)
C. Graphic Processing Unit (GPU)
D. Computer Processing Unit (CPU) speed increase by using overcloking
E. High Random Access Memory (RAM) configuration
You are developing a hands-on workshop to introduce Docker for Windows to attendees.You need to ensure that workshop attendees can install Docker on their devices.Which two prerequisite components should attendees install on the devices? Each correctanswer presents part of the solution.NOTE: Each correct selection is worth one point.
A. Microsoft Hardware-Assisted Virtualization Detection Tool
B. Kitematic
C. BIOS-enabled virtualization
D. VirtualBox
E. Windows 10 64-bit Professional

You are a data scientist creating a linear regression model.You need to determine how closely the data fits the regression line.Which metric should you review?
A. Coefficient of determination
B. Recall
C. Precision
D. Mean absolute error
E. Root Mean Square Error
You are building a recurrent neural network to perform a binary classification. You reviewthe training loss, validation loss, training accuracy, and validation accuracy for each training epoch.You need to analyze model performance.Which observation indicates that the classification model is over fitted?
A. The training loss .stays constant and the validation loss stays on a constant value andclose to the training loss value when training the model.
B. The training loss increases while the validation loss decreases when training the model.
C. The training loss decreases while the validation loss increases when training the model.
D. The training loss stays constant and the validation loss decreases when training the model.
