To answer this question, you need to understand the utilities available in mainframe environments for managing PS (Physical Sequential) and PDS (Partitioned Data Set).
Let's go through each option to understand why it is correct or incorrect:
Option A) IEWL - This option is incorrect because IEWL (Interactive Edit and Link) is a utility used for linking and editing programs, not for creating, deleting, or copying PS/PDS.
Option B) DSNHPC - This option is incorrect because DSNHPC (Data Set High-Level Programming Control) is a utility used for managing DB2 objects, not for creating, deleting, or copying PS/PDS.
Option C) IGYCRCTL - This option is incorrect because IGYCRCTL (COBOL Compiler Control) is a utility used for controlling the compilation of COBOL programs, not for creating, deleting, or copying PS/PDS.
Option D) IEFBR14 - This option is correct because IEFBR14 (Dummy Utility) is a utility used for creating, deleting, or copying PS/PDS. It is commonly used to create a new PS or PDS, delete an existing PS or PDS, or copy a PS or PDS to another location.
The correct answer is D) IEFBR14. This option is correct because IEFBR14 is the utility used to create, delete, or copy PS/PDS.
