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.
Select and Place:

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?

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?

You need to use the ScaleR distributed processing in an Apache Hadoop environment.
Which data source should you use?

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.
NOTE: Each correct selection is worth one point.

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?

You have a slow Map Reduce job.
You need to optimize the job to control the number of mapper and runner tasks.
Which function should you use?

You have an Apache Hadoop Hive data warehouse. RevoScalerR is not installed.
You need to sort the data according to the variables in the dataset.
What should you do?

Note: This question is part of a series of questions that use the same scenario. For your convenience, the
scenario is repeated in each question. Each question presents a different goal and answer choices, but the text
of the scenario is exactly the same in each question in this series.
Start of repeated scenario
You are developing a Microsoft R Open solution that will leverage the computing power of the database server
for some of your datasets.
You are performing feature engineering and data preparation for the datasets.
The following is a sample of the dataset.

End of repeated scenario.
You have the following R code.

Which function determines the variable?

Start of repeated scenario
You are developing a Microsoft R Open solution that will leverage the computing power of the database server
for some of your datasets.
You are performing feature engineering and data preparation for the datasets.
The following is a sample of the dataset.

End of repeated scenario.
You need to analyze the dataset without the missing values. The solution must not remove the missing values
from the dataset.
