SAS A00-415 Sample Questions:

01. A tax authority runs the following against a CAS table of filings:
proc fedsql; select filer_id, amount_due from taxcas.filings_q2 where amount_due > 5000; quit;
What does this query return?
a) All columns in taxcas.filings_q2, sorted in descending order by amount_due.
b) Every row in taxcas.filings_q2, with amount_due values capped at 5000.
c) A count of the rows in taxcas.filings_q2 where amount_due exceeds 5000, with no individual rows shown.
d) Only the filer_id and amount_due columns, restricted to rows where amount_due exceeds 5000.
 
02. A university research group needs read access, across several researchers' sessions, to a very large dataset that resides on an external network file system and changes only rarely. One researcher proposes loading a full copy into a global caslib; another proposes pointing a DNFS caslib directly at the external file.
Which consideration best supports preferring the DNFS approach here?
a) The global-caslib option would make the data private to only one researcher, which defeats the group's requirement
b) A global caslib cannot be shared across multiple researchers' sessions, so it is disqualified outright for this shared-access need.
c) Reading the large file directly through a DNFS caslib avoids a full copy/load step while still allowing the researchers' sessions to access the data at its external location
d) DNFS caslibs are required by SAS Viya for any dataset larger than a single gigabyte, regardless of whether the file is local or lives on a network location
 
03. An analyst at an insurance company is deciding between saving and dropping a CAS table called CLAIMS_STAGING.
Which statement correctly distinguishes the two operations?
a) Saving persists the table's data back to the caslib's data source, while dropping only removes the table from CAS memory without affecting any already-saved copy.
b) Saving removes the table from memory, while dropping writes it back to the data source, reversing the roles the two PROC CASUTIL actions actually play
c) Saving and dropping both permanently delete the underlying source file, just at different times
d) Dropping a table saves it to the caslib's data source first, so the two operations are functionally identical.
 
04. At a regional bank, a programmer submits a DATA step where both the input and output tables are CAS tables referenced through the caslib mycas, for example data mycas.txn_clean; set mycas.txn_raw; run;.
Where does this DATA step's processing actually execute?
a) Split evenly between the CAS server and the SAS Compute Server for the same step.
b) On the CAS server, distributed across CAS worker nodes and multi-threaded.
c) On the traditional SAS Compute Server, exactly as a SAS 9 DATA step would.
d) On the local desktop running SAS Studio, without involving a server.
 
05. In SAS Viya, a caslib is best described as which of the following?
a) A CAS action that lists every session currently connected to a CAS server, along with each session's owning user and the caslibs currently assigned to it
b) A reference that combines a path to a data source with an access-control layer, used to load, save, and share CAS tables
c) A single in-memory CAS table that has already been loaded and is ready for analysis
d) A temporary scratch area that exists only for the life of one CAS action and is discarded immediately afterward.
 
06. What best characterizes a personal caslib in SAS Viya?
a) A caslib reserved for storing only user-defined formats rather than CAS tables.
b) A caslib whose tables are promoted to global scope the moment they are loaded
c) A caslib that is private to an individual session's user, commonly used as that user's default working area
d) A caslib that can only be created by a CAS server administrator, with no option for an ordinary session's user to define one.
 
07. What is the primary role of PROC CASUTIL in a Viya programming workflow?
a) Managing the lifecycle of CAS tables — listing, loading, saving, dropping, and promoting them
b) Converting a SAS 9 data set into a permanent SAS Viya license file
c) Compiling CASL scripts into a standalone executable file before any action in the script can run.
d) Enforcing row-level security policies on CAS server hardware
 
08. Which statement correctly describes a global caslib in SAS Viya?
a) It restricts access so that only the session that created it can ever reference its tables
b) It makes the caslib, and CAS tables promoted within it, available for use by more than one session or user with appropriate access
c) It is limited to reading a single external file format and cannot host a saved CAS table
d) It deletes any CAS table inside it as soon as the creating session ends, treating every table in the caslib as temporary regardless of how it was loaded.
 
09. Which two statements about SAS Viya caslib types are accurate?
(Choose two.)
a) Any caslib becomes a personal caslib the moment a second user attempts to access it, switching type based on who connects.
b) A personal caslib is private to the session's own user, commonly serving as that user's default working area
c) A global caslib is intended to be shared across multiple sessions/users with appropriate access
d) A DNFS caslib guarantees that every table within it is promoted to global scope as soon as it is loaded.
e) A path-based caslib and a DNFS caslib are entirely unrelated mechanisms with no shared lineage
 
10. While reviewing a CAS session log for a telecom usage-data project, a programmer notices entries such as table.loadTable and table.promote being executed against the CAS server.
What does the two-part naming pattern shown in these log entries represent?
a) The action set the action belongs to, followed by the specific action name within that set.
b) A caslib name followed by the CAS table name it contains, written using the two-level libref-style reference a programmer would use in code.
c) A FEDSQL schema name followed by the query being executed.
d) A SAS 9 libref followed by the data set name being processed.
