Question 1

Which of the following components is responsible for managing user sessions and ensuring that the processing of SAS tasks is distributed effectively across the SAS Viya environment?

Options :

A : SAS Event Stream Processing (ESP)

B : SAS Micro Analytic Service (MAS)

C : SAS Environment Manager

D : SAS Cloud Analytic Services (CAS)

Answer: D

Question 2

You are working with a large, partitioned dataset in a CAS session and you want to ensure that a PROC MEANS calculation is performed in parallel across all data partitions to enhance performance. Which option would you use to accomplish this?

Options :

A : Use the PARTBY statement in the PROC MEANS code to specify the variable that defines the data partitions.

B : Explicitly define a BY statement and sort the data by the partitioning variable before calling PROC MEANS.

C : Use the NWAY option in the PROC MEANS code to enforce group processing only on the class variables.

D : Implement an ORDER BY clause in a preceding PROC SQL step to arrange the data by partitions.

Answer: A

Question 3

Consider the following SAS code which intends to retrieve values from an array to calculate the average sales for the first quarter: `

data work.quarterly_sales;

array qtr_sales[3];

do i=1 to 3;

set sales_data(keep=jan feb mar);

qtr_sales[i] = sales_data{i};

end;

avg_sales = mean(of qtr_sales[*]);

run;

The dataset `sales_data` has three variables named `jan`, `feb`, and `mar`, containing the sales for each month of the first quarter. Which statement is true regarding this code?

Options :

A : The code will correctly calculate `avg_sales` as the average of the first quarter sales.

B : The `set` statement is incorrectly placed inside the loop, causing an error.

C : The mean function is not used correctly and will result in an error.

D : The array subscript cannot use `sales_data{i}`, it should be `qtr_sales[i] = sales_data[i];`.

Answer: B

Question 4

A SAS Viya data analyst is tasked with selecting a random subset of data from a dataset called 'CustomerData', which contains over 1 million records. The requirement is to analyze a manageable subset without any bias. How should the analyst use the 'subSet=' parameter in a procedure to ensure a random selection?

Options :

A : PROC SURVEYSELECT DATA=CustomerData subSet=/METHOD=SRS SAMPRATE=0.01 OUT=SampleData;

B : PROC SURVEYSELECT DATA=CustomerData METHOD=SRS SAMPRATE=0.01 OUT=SampleData;

C : PROC SURVEYSELECT DATA=CustomerData subSet=(RANDOM 0.01) OUT=SampleData;

D : PROC SURVEYSELECT DATA=CustomerData / subSet=(RANDOM 0.01) OUT=SampleData;

Answer: B

Question 5

Which of the following is a true statement regarding variable scope in CASL?

Options :

A : Global variables declared outside of any function or action block are accessible only within the same script and cannot be accessed by other scripts or sessions.

B : CASL does not support local variables; all variables are global and can be accessed from any part of the program.

C : Variables in CASL are dynamically typed, and their scope is determined at runtime based on the execution context.

D : Local variables in CASL can be accessed and modified by any other blocks of code within the same action set.
