Question 1

A data analyst is creating a SAS Viya program that requires the user to input a date value at the beginning of the session, which will then be used to filter a dataset showing sales within a certain range. The date format expected is "YYYY-MM-DD". Which method allows the program to prompt the user for an input parameter and ensures the value is stored in a macro variable with the appropriate format for further use in the program?

A : %let sales_date = %sysget(YYYY-MM-DD);

B : %let sales_date = %str(YYYY-MM-DD);

C : %let sales_date = %sysfunc(inputn(&sysparm.;, yymmdd10.));

D : %let sales_date = %window('Enter sales date in format YYYY-MM-DD');

Answer: C

Question 2

Given a dataset named 'orders' with variables 'orderId', 'customerId', and 'orderValue', you are tasked with writing a DATA Step to accumulate the total order value per customer. Which of the following codes will correctly produce a dataset with a total for each customer?

A : data customerTotals;set orders;by customerId;retain totalValue;if first.customerId then totalValue=0;totalValue + orderValue;if last.customerId then output;run;

B : data customerTotals;set orders;by customerId;totalValue + orderValue;if last.customerId then output;run;

C : data customerTotals;set orders;by customerId;retain totalValue 0;if first.customerId then call missing(totalValue);totalValue + orderValue;if last.customerId then output;run;

D : data customerTotals;set orders;retain totalValue 0;totalValue = totalValue + orderValue;output;run;

Answer: A

Question 3

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?

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 4

An analyst is developing a data manipulation task that involves sorting a large dataset and merging it with another. Given two environments, one using serial processing and the other using parallel processing, which of the following statements would be true regarding performance expectations?

A : Sorting and merging would take longer in the parallel processing environment, as these tasks are I/O intensive.

B : There would be no difference in performance between the two environments as the types of operations involved do not benefit from parallel execution.

C : Sorting and merging would be faster in the serial processing environment due to the simpler nature of the computation.

D : Sorting and merging would benefit from the parallel processing capabilities leading to potential decreases in execution time.

Answer: D

Question 5

An analyst is working with a CAS session and needs to save a table permanently in a CAS library. What statement must the analyst append to ensure the data will not be lost when the session ends?

A : The analyst must use the SAVE statement specifying the library: SAVE TABLE mytable TO CASLIB mycaslib;

B : The analyst should save the table as a SAS data set in the DATA step and then assign it a libref using CASLIB statement.

C : The analyst must use the TABLESAVE statement in PROC CAS to direct the CAS engine to save the data: PROC CAS; TABLESAVE / caslib="mycaslib" name="mytable"; RUN;

D : The analyst has to use the CAS Engine's "PERSIST" statement to ensure persistence: PROC CASUTIL; SAVE caslib=mycaslib; persist=true; RUN;
