A00-215 Exam Dumps and Practice Questions

The program fails because option C is correct: you must include the dataset height2 in the DATA statement. The DATA step is trying to write to a dataset named height2, which has not been defined in the DATA statement. The correct syntax to create two datasets in one DATA step is to list them both in the DATA statement like so:

data height1 height2;

The use of numbers in dataset names is not a problem in SAS, nor is outputting to different data sets within a single DATA step. Additionally, using two different DATA statements for HEIGHT1 and HEIGHT2 is not required and is not the cause of the failure.

SAS documentation on the DATA statement and creating multiple data sets.

In SAS, datasets can be either temporary or permanent, depending on the library where they are stored. Temporary datasets are stored in the Work library and are deleted at the end of the session, while permanent datasets reside in user-defined libraries or in libraries that refer to a more persistent storage location.

For this question:

B .

Mylib.new: This is a permanent dataset. The prefix 'Mylib' suggests it is stored in a user-defined library (not the temporary 'Work' library), implying that the data persists beyond the current session unless explicitly deleted or if the library's link to the storage location is removed.

D . Temp.new: Despite the potentially misleading name 'Temp', if this dataset is not explicitly stored in the Work library, it could indeed be permanent. The permanence of a dataset is determined by its library reference, not by its name. If 'Temp' is a user-defined library linked to a persistent storage, then 'Temp.new' is also permanent.

C . Work.new: This dataset is explicitly temporary as it is stored in the Work library, which is cleared at the end of the SAS session.

A . New: Without additional context about the library, 'New' does not provide enough information to determine its permanence. It could be either temporary or permanent depending on the library it references.

The correct answer is option D, which uses the LIBNAME statement correctly to assign a library reference to an Excel workbook and specifies the correct syntax for accessing a worksheet within that workbook. The syntax for this option is:

libname exlib xlsx 'c:\class.xlsx';

proc print data=exlib.class_test;

run;

This code snippet assigns the library reference exlib to the Excel workbook located at c:\class.xlsx using the XLSX engine. The PROC PRINT step is then used to display the contents of the worksheet named CLASS_TEST within that workbook. The library reference exlib combined with the dataset name class_test (following the .) correctly specifies the worksheet to be printed. The other options (A, B, C) are incorrect due to various reasons: incorrect syntax for the LIBNAME statement, incorrect specification of the dataset to be printed, and incorrect path specifications.

The PROC SORT step in SAS is used to sort data sets by one or more variables. The syntax for the proc sort step requires the by statement to specify the variable(s) by which to sort the data. The correct answer is option A:

proc sort data=Names;

by Name;

run;

This sorts the data set by the variable 'Name' in alphabetical order, which matches the sorted NAMES data set shown in the question. Option B uses orderby, which is not a valid SAS statement. Option C sorts by 'Age', which would not give the same result as shown in the question. Option D also incorrectly uses orderby.
