Question 1

An analytics firm is looking to harness the power of in-memory analytics for complex computations and wants to decide between SAS Compute Server and SAS Cloud Analytics Services (CAS). Which scenario best justifies the choice of utilizing CAS over SAS Compute Server?

Options :

A : The firm requires batch processing capabilities for large datasets that do not fit into memory.

B : The company demands a distributed, in-memory analytics engine to analyze big data at unprecedented speeds.

C : There is a need for a traditional analytics environment that supports long-established, disk-based processing.

D : The firm-s analytics workload is light and does not require the advanced, high-performance capabilities of in-memory processing.

Answer: B

Question 2

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

B : Local

C : Active

D : Personal

Answer: D

Question 3

During a SAS Viya programming routine, a programmer attempts to load a dataset named 'customer_info' from a SAS data library named 'saslib' into the CAS environment. However, the programmer receives an error. What could be a possible reason for this if the LOAD CASDATA= statement used was: `load casdata=saslib.customer_info casout=caslib.customer_data;`

Options :

A : The 'saslib' library was not defined in the CAS server.

B : The target CAS library 'caslib' does not exist on the CAS server.

C : The dataset 'customer_info' does not exist in the 'saslib'.

D : All of the above reasons could cause an error.

Answer: D

Question 4

2:** Imagine you are performing data analysis in SAS Viya and you have created several in-memory tables in your session. After performing your analysis, you decide to drop all the in-memory tables you have created to free up resources. Which of the following CAS actions allows you to drop an in-memory table named 'sessionData'?

Options :

A : table.dropTable / name='sessionData';

B : drop / table='sessionData';

C : table.drop / name='sessionData';

D : endSession / dropTables=true;

Answer: C

Question 5

A data analyst is working on a SAS Viya project and needs to read an external CSV file into the SAS Viya environment. The external CSV file is located on a network drive that the SAS Viya environment can access. Which of the following methods would be the best practice for specifying the location of the input data to ensure that the data can be efficiently imported?

Options :

A : Hard-code the full network path to the CSV file in the data step.

B : Use the LIBNAME statement with the CAS engine to assign a libref to the network location.

C : Import the data to a local machine and then upload it to the SAS Viya server using the SAS Studio interface.

D : Store the file on a cloud storage service and use PROC HTTP to access it.

Answer: B
