Question 1

When working with CAS (Cloud Analytic Services) in SAS Viya, understanding column data types is crucial for appropriate data manipulation. Given a scenario where you are required to perform arithmetic operations on a set of variables within a CAS table, which of the following data types would you ensure these variables are set to before proceeding with the operation?

Options :

A : varchar

B : double

C : binary

D : nvarchar

Answer: B

Question 2

When working with the CAS procedure PROC CASUTIL to load data into the CAS server, what is the effect of setting the DATALIMIT= option to a specific value, such as DATALIMIT=100?

Options :

A : It specifies that only the first 100 bytes of the data set should be loaded.

B : It sets the limit for the maximum number of variables to be included in the output table in the CAS server.

C : It imposes a restriction on the number of observation rows to be processed by the CAS action.

D : It controls the maximum number of characters for string variables to be loaded into the CAS server.

Answer: C

Question 3

When using the CASUSER caslib in a SAS Viya environment, which of the following statements is correct regarding data accessibility?

Options :

A : Data in the CASUSER caslib is private to each individual user and is deleted after the user-s session ends.

B : All users share the same CASUSER caslib, which allows for easy data sharing across the SAS Viya environment.

C : Data in the CASUSER caslib is replicated across all nodes in the CAS cluster to ensure high availability.

D : The CASUSER caslib is read-only, and users can only import data to other caslibs.

Answer: A

Question 4

When analyzing the time between customer purchases, a data analyst needs to extract the month from a date variable 'purchase_date' in the SAS Viya environment. Which function can be appropriately used to extract the month component from the date?

Options :

A : `DATEPART()`

B : `MONTH()`

C : `DAY()`

D : `EXTRACT()`

Answer: B

Question 5

You are working on a project that requires heavy machine learning model training and scoring. You have access to both the SAS server and the CAS server. Which server should you choose for optimal performance of these tasks?

Options :

A : Use the SAS server for model training and the CAS server for model scoring.

B : Use the CAS server for both model training and scoring to leverage its in-memory processing.

C : Use the SAS server for both model training and scoring to ensure model compatibility.

D : Use the SAS server for model training due to its extensive library of procedures and transfer the scored model to the CAS server for deployment.
