A00-231 Exam Preparation Material | SAS 9.4 Base Programming -- Performance-based exam

Prepare for the A00-231 with reliable study materials, practice questions, and key exam insights.

Prepare for the A00-231 SAS 9.4 Base Programming -- Performance-based exam with CertQueen's independently developed study resources. Review important concepts, practice scenario-based questions, and use clear explanations to identify areas that require further study.

Question#1

The following SAS program is submitted:



What are the values for x and y in the output data set?

A. There is a syntax error: x and y are both set to missing.
B. There is a syntax error: x=2, y is set to missing.
C. There are no errors: x=2, y=200.
D. There is a logic error: x=2, y=27.

Question#2

SIMULATION
Scenario:
Continuing with the previous program (program27), add a PROC SORT step that satisfies the following criteria:
o Creates the output dataset results.output27b
o Sorts the observations by order.
o Removes duplicate values of the first occurrence found during the sort.
What is the value of Employee_ID for observation 98 inresults.output27b?

A. 120779

Explanation:
proc sort data=cert.input27 out=results.output27b nodupkey;
by descending postal_code;
run;
proc print data=results.output27b (firstobs=98 obs=181);
var employee_ID;
run:

Question#3

SIMULATION
Scenario:
This project will use data setcert.input36. At any time, you may save your program asprogram36 in cert\programs.
Write a SAS program that will clean the data incert.input36as follows:
Step 1:
create a temporary data set, cleandata36.
In this data set, convert all case.
Then keep only observations with group equal to 'A' or 'B'.
Step 2:
Determine the MEDIAN value for the Kilograms variable for each group(A,B) in the cleandata36
data set. Round MEDIAN to the nearest whole number.
Step 3:
Create results.output36 from cleandata36
Ensure that all values for variable Kilogramsare between 40 and 200, inclusively.
If the value is missing or out of range, replace the value with the MEDIAN Kilograms value for the respectivegroup(A, B) calculated in step 2

A. 86.5

Explanation:


Question#4

SIMULATION
Scenario:
This project will use data set cert.input08a and cert.input08b. At any time, you may save your program as program08 in cert\programs.
Both data sets contain a common numeric variable named ID.
Write a program that will use a SAS DATA Step to:
o Combine data sets cert.input08a and cert.input08b by
matching values of the ID variable.
o Write only observations that are in both data sets to a
new data set named results.match08.
o Write all other non-matching observations from either data set to a new data set named results.nomatch08. o Exclude all variables that begin with
"ex" from results.nomatch08.
How many variables (columns) are in results.match08

A. 117

Explanation:
proc sort data=cert.input08b out=work.input08b;
by ID;
run:
data results.match08 results.nomatch08 (drop=ex: );
merge work.input08a (in=a) work.input08b (in=b);
by ID;
if a and b then output results.match08;
else output results.nomatch08;
run;
proc contents data=results.match08;
SAS code that could be used to solve this project:
proc
sort data=cert.input08a out=work.input08a;
by ID;
run:
run;
proc contents data=results.nomatch08;
run;
The correct answer is: 117

Question#5

The variable Name in the data set Employeehas a $CHAR10. format. The variable Name in the data set Sales has a $CHAR15. format.
The following SAS program is submitted: data both;
length name $ 20;
merge sales employee;
by id;
run;
What is the format for the variable Name in the data set Both?
Select one:

A. $20
B. $CHAR10
C. $CHAR15
D. $CHAR20
