Question 1

A programmer needs to execute a series of data preparation steps that rely on traditional SAS data set access, manipulation, and reporting procedures, and some steps are highly I/O intensive due to the data size. Based on these requirements, which environment should the programmer choose for the execution of this code?

Options :

A : The Compute Server, to utilize the traditional SAS programming environment

B : The CAS environment, to benefit from its in-memory processing power

C : The client machine, because I/O intensive tasks are best handled locally

D : The execution environment does not matter as long as enough memory is allocated

Answer: A

Question 2

A programmer wants to accumulate the total sales for each month in a dataset named 'monthly_sales' that has two variables: 'month' and 'sales'. Which DATA Step code properly accumulates the total sales for each month?

Options :

A : data totals;set monthly_sales;retain total_sales;total_sales + sales;run;

B : data totals;set monthly_sales;by month;if first.month then total_sales=0;total_sales + sales;if last.month then output;run;

C : data totals(drop=month);set monthly_sales;total_sales + sales;output;run;

D : data totals;set monthly_sales;retain total_sales 0;total_sales + sales;output;run;

Answer: B

Question 3

You are using the SIMPLE action set in a data analysis task and want to perform a data transformation by applying a mathematical formula to a variable in your dataset. Which action would allow you to create a new variable with these transformed values?

Options :

A : simple.transmute

B : simple.compute

C : simple.modify

D : simple.impute

Answer: A

Question 4

During a CAS session, you want to analyze a large dataset that captures customer interactions. Your objective is to understand the distribution of the duration of these interactions. Considering that you're interested in the frequency distribution and descriptive statistics of a single variable, which procedure would you select?

Options :

A : PROC UNIVARIATE

B : PROC SGPLOT

C : PROC CORR

D : PROC GLM

Answer: A

Question 5

When a user submits a PROC MEANS in a SAS Viya environment, the procedure is automatically directed to run in a specific execution context based on the data's location. Assuming the PROC MEANS is using a dataset that resides within the CAS server, where will the code execute?

Options :

A : The code will execute locally on the user-s machine.

B : The code will execute on the SAS Viya compute server accessing the data via implicit SQL pass-through.

C : The code will execute within the CAS server where the dataset resides.

D : The code execution will prompt the user to choose the execution environment. E. The code will execute within the SAS Viya environment, but the exact location will be determined by the network latency.
