Question 1

You have developed a SAS Viya application that generates several data visualizations. The visualizations need to be updated periodically based on user interactions. What is the best practice for managing the data and scripts for these visualizations?

Options :

A : Maintain the data and scripts on the server-side, and utilize server processing to update visualizations.

B : Store the scripts on the client-side and push them to the server whenever an update is required.

C : Keep the data on the client-side and transfer it to the server every time a visualization update is triggered.

D : Store visualization scripts on the client-side for easier debugging, and use AJAX calls to pull data from the server as needed.

Answer: A

Question 2

A data analyst needs to load a data set named 'sales_data' into the CAS (Cloud Analytic Services) environment to perform data analysis using SAS Viya. The 'sales_data' is currently stored in the 'my_data' library. Which of the following LOAD CASDATA= statement options would correctly load the dataset into the CAS server so it can be accessed using the default casuser library?

Options :

A : load casdata=sales_data casout=casuser;

B : caslib mylib data='my_data.sales_data' casout=casuser;

C : load data=my_data.sales_data casout=casuser;

D : load casdata=my_data.sales_data casout=casuser;

Answer: D

Question 3

A data analyst needs to run a data manipulation task that involves sorting a table by multiple columns, then creating a new column based on a conditional statement. Which of the following sets of actions should be used in the given scenario when programming in SAS Viya?

Options :

A : table.loadTable followed by table.sortTable and then table.addTable

B : table.loadTable followed by table.sort and then column.addDerivedColumn

C : table.fetch followed by column.sort and then column.addCondition

D : fedSql.execDirect for the entire manipulation in a single step

Answer: B

Question 4

A dataset contains the column 'TotalSpent,' which records the total amount of money, including cents, each customer has spent to date. Which of the following data types best ensures accurate arithmetic calculations and comparisons?

Options :

A : Integer

B : VARCHAR

C : Double

D : Boolean

Answer: C

Question 5

A SAS programmer wants to use the SESSREF= option in a DATA step to access an in-memory table within a CAS (Cloud Analytic Services) session that is already loaded with datasets. They define the DATA step as follows:

Which of the following is true regarding the DATA step above?

Options :

A : The DATA step will fail because the SESSREF= option should not be used in this context.

B : The DATA step will execute successfully, and work.queryResult will contain the filtered data from the CAS session.

C : The SESSREF= option is incorrectly formatted; it should be defined within the SET statement.

D : The SESSREF= option is not required as the libref 'mycas' is already used in the SET statement.
