Question 1

You are designing an algorithm that will perform a series of matrix multiplication operations for a large-scale machine learning application. Which processing technique would likely yield a better performance given the computational requirements of matrix multiplication in this context, and why?

Options :

A : Serial processing, because matrix multiplication operations are inherently sequential.

B : Parallel processing, because matrix multiplication is computationally demanding and can be effectively distributed among processors.

C : Serial processing, because parallel processing incurs a synchronization overhead that negates the benefits of distributing the matrix multiplication tasks.

D : Parallel processing, because it avoids the overhead of context switching associated with serial processing.

Answer: B

Question 2

You are designing a table to store customer information for a loyalty program. One of the fields is 'BirthDate,' which stores the date of birth of each customer. What data type should you assign to 'BirthDate' to ensure proper date operations can be performed?

Options :

A : Char

B : Numeric

C : Date

D : VARCHAR

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 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 5

You are tasked to join two datasets named 'sales' and 'returns' in the CAS server to analyze the returned items and their original sales data. The 'sales' dataset contains a variable 'OrderID', and the 'returns' dataset contains a variable 'ReturnID', which maps to the sales order. What code snippet would efficiently join these two tables using SAS Viya's capabilities?

Options :

A : proc sql; create table sales_return as select * from sales join returns on sales.OrderID = returns.ReturnID; quit;

B : proc casutil; load data=sales return=returns out=sales_return; join condition="OrderID = ReturnID"; quit;

C : data sales_return; merge sales(in=a) returns(in=b); by OrderID; if b; run;

D : proc fedsql; create table sales_return as select * from sales inner join returns on sales.OrderID = returns.ReturnID; quit;
