Question 1

A data analyst is using the fedSQL action set to combine data from separate tables stored in a distributed environment. They want to perform a left join on two tables, 'customers' and 'orders', based on the customer ID. Which of the following fedSQL statements accomplishes this?

A : PROC FEDSQL; CREATE TABLE results AS SELECT * FROM customers INNER JOIN orders ON customers.customer_id = orders.customer_id; QUIT;

B : PROC FEDSQL; CREATE TABLE results AS SELECT * FROM customers LEFT JOIN orders ON customers.id = orders.customer_id; QUIT;

C : PROC FEDSQL; CREATE TABLE results AS SELECT * FROM customers t1 LEFT JOIN orders t2 ON t1.customer_id = t2.customer_id; QUIT;

D : PROC FEDSQL; CREATE TABLE results AS SELECT * FROM customers FULL JOIN orders ON customers.customer_id = orders.customer_id; QUIT;

Answer: C

Question 2

Assume that you are working with a large dataset in CAS, and you have a need to create a flag variable that indicates whether certain criteria are met. This flag is based on a calculation that you do not want to repeat in multiple places throughout your DATA step code. How can the `computedVarsProgram=` parameter be utilized to optimize performance and maintainability?

A : Use the `computedVarsProgram=` parameter to define the flag calculation and reference the flag variable later in the DATA step without redefining the calculation.

B : Set the `computedVarsProgram=` parameter to create a macro variable with the desired flag value so it can be used throughout the DATA step.

C : Apply the `computedVarsProgram=` parameter in multiple DATA steps so each one can perform the flag calculation independently.

D : Invoke the `computedVarsProgram=` parameter at the end of the DATA step to store the results of the flag calculation for subsequent steps.

Answer: A

Question 3

You have a dataset that includes a character column named 'char_income' which contains numeric values formatted as strings, such as "34500", "29800", etc. You need to convert this to a numeric column 'num_income' to perform calculations. Which code snippet would correctly perform this conversion?

A : data new_dataset; set old_dataset; num_income = input(char_income, 8.); run;

B : data new_dataset; set old_dataset; num_income = input(char_income, comma8.); run;

C : data new_dataset; set old_dataset; num_income = char_income * 1; run;

D : data new_dataset; set old_dataset; num_income = put(char_income, 8.); run;

Answer: A

Question 4

When defining a variable in a CAS table using PROC CAS, which of the following data types requires specifying the maximum length attribute?

A : double

B : varchar

C : int64

D : numeric

Answer: B

Question 5

When setting up a data step in a SAS Viya environment, your code needs to read a database table hosted on a remote server, which is registered as a library in SAS Viya's library manager. What would be the appropriate LIBNAME statement to ensure that your data step can access this table?

A : libname mylib base 'server_path_to_data';

B : libname mylib meta LIBRARY="RemoteServerLib";

C : libname mylib sasiohttp HOSTNAME="remoteserver.com";

D : libname mylib v9 'server_path_to_data';

Answer: B
