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

You are working on a SAS Viya programming task that involves the manipulation of customer transaction data. You have a numeric variable named 'Trans_Amount', which stores the transaction amounts in dollars and cents (e.g., 123.45). However, you notice that some transaction amounts are incorrectly recorded as negative values due to a data entry error. To ensure accurate analyses, what numeric property of the 'Trans_Amount' variable could you use or modify to correct these values in your programming code?

Options :

A : Set a user-defined format to display negative numbers as positive.

B : Utilize the ABS function to convert negative values to their absolute values.

C : Change the variable-s length to accommodate larger numbers.

D : Implement a WHERE clause to filter out all negative values.

Answer: B

Question 3

When a user attempts to view the contents of a caslib using PROC CASUTIL, they only want to see tables that contain the word "sales" in their name. Which of the following PROC CASUTIL statements would correctly perform this operation while utilizing the most efficient use of resources?

Options :

A : proc casutil; listtables caslib='default' where(name like '%sales%'); run;

B : proc casutil; listtables caslib='default'; run; where name contains 'sales';

C : proc casutil; listtables caslib='default'; run; title 'Tables with sales';

D : proc casutil; listtables caslib='default'; run;

Answer: A

Question 4

During a routine maintenance, a data analyst needs to drop multiple tables from the SAS Viya library named 'analysis'. The analyst has to ensure that a specific table 'temp_results' remains undropped for further review. Which SQL statement should the analyst execute to accomplish this task efficiently while avoiding the deletion of 'temp_results'?

Options :

A : PROC SQL; DROP TABLE analysis._ALL_ EXCEPT temp_results; QUIT;

B : PROC SQL; DROP TABLE analysis. EXCEPT temp_results; QUIT;

C : PROC SQL; DROP ALL TABLES IN analysis WHERE table_name NE 'temp_results'; QUIT;

D : PROC SQL; DROP TABLE analysis.table_name WHERE table_name NE 'temp_results'; QUIT;

Answer: C

Question 5

A data scientist is working on a SAS Viya environment and wants to access data files stored in the default location where personal files are kept when the SAS Viya session starts. Which of the following CASLIB attributes should be considered to directly access these files?

Options :

A : Session
