Identify two features of obfuscation. (Choose two.)
A.
The Import and Export utilities accept wrapped files.
B.
SQL’ Plus cannot process the obfuscated source files.
C.
Only the wrap utility can obfuscate multiple programs at a time.
D.
Both the DBMS_DDL package and the Wrap utility can obfuscate multiple programs at a time.
E.
The source code is visible only through the DBA_SOURCE view and not through the
USER_SOURCE or ALL_SOURCE View
Explanation:
a and c are correct.
Obfuscation, or wrapping, of a PL/SQL unit is the process of hiding the PL/SQL source code. Wrapping can be done with the wrap utility and DBMS_DDL subprograms. The wrap utility is run from the command line and processes an input SQL file, such as a SQL*Plus installation script. The DBMS_DDL subprograms wrap a single PL/SQL unit, such as a single CREATE PROCEDURE command, that has been generated dynamically.
The advantages of obfuscating, or hiding, the source code of PL/SQL units with the wrap utility or wrap subprograms of the DBMS_DDL package are:
It is difficult for other developers to misuse your application, or business competitors to see your algorithms.
Your source code is not visible through the USER_SOURCE, ALL_SOURCE, or DBA_SOURCE data dictionary views.
SQL*Plus can process the obfuscated source files.
The Import and Export utilities accept wrapped files. You can back up or move wrapped procedures.
