Which three actions should you perform?
You have a dataset that has multiple blocks and only numeric variables.
You are computing in a local compute context.
You plan to lag a variable named x to create a new variable named x_lagged by using a transform function. You
will create a new element in the output of the function.
You need to minimize the number of missing values.
Which three actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

You are running a large logistic regression for 1,000 feature variables by using the LoisticRegression() function
in the MicrosoftML package. All of the predictor variables are numeric.Currently, you specify the input variables separately by using the following formula.
Outcome ~ Feature000 + Feature001 + Feature002 + … + Feature999
You discover that it takes 20 minutes to estimate each model.
You need to reduce the amount of time required to estimate each model without losing any information in the
predictors.
What should you do?
Which statement should you use for each environment?
DRAG DROP
You need to set the compute context for three different target environments.
Which statement should you use for each environment? To answer, drag the appropriate statements to the
correct execution contexts. Each statement 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.

Which function should you use?
You have a dataset that has a character variable.
You need to create a bag of counts of n-grams.
Which function should you use?
Which R code segment should you use?
You plan to analyze data on a local computer. To improve performance, you plan to alternate the operation
between a Microsoft SQL Server and the local computer.
You need to run complex code on the SQL Server, and then revert to the local compute context.
Which R code segment should you use?
Which data source should you use?
You need to use the ScaleR distributed processing in an Apache Hadoop environment.

You are planning the compute contexts for your environment.
You need to execute rx-function calls in parallel.
What are three possible compute contexts that you can use to achieve this goal? Each correct answer presents
a complete solution.

You have cloud and on-premises resources that include Microsoft SQL Server and a big data environment in
Apache Hadoop.
You have 50 billion fact records.
You need to build time series models to execute forecasting reports on the fact records.
What should you use?
Which function should you use?
You have a slow Map Reduce job.
You need to optimize the job to control the number of mapper and runner tasks.
