To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) IEBGENER, IEBCOPY - These system utilities are used for copying and generating datasets, but they do not specifically deal with maintaining and managing catalogs. Therefore, this option is incorrect.
Option B) IEBCOPY, IEBCOMPR - IEBCOPY is a system utility used for copying, moving, and merging datasets. IEBCOMPR is a system utility used for comparing datasets. While IEBCOPY can be used for managing catalogs, IEBCOMPR does not specifically deal with catalog maintenance. Therefore, this option is partially correct.
Option C) IEHPROGM, IEBGENER - IEHPROGM is a system utility used for program management and does not specifically deal with catalog maintenance. IEBGENER is used for generating datasets but not for catalog maintenance. Therefore, this option is incorrect.
Option D) IEHLIST, IEHPROGM - IEHLIST is a system utility used for listing datasets and their attributes, including catalog information. IEHPROGM is a system utility used for program management. Both IEHLIST and IEHPROGM can be used for maintaining and managing catalogs. Therefore, this option is correct.
Option E) IEHPROGM, IEBCOPY - IEHPROGM is a system utility used for program management and does not specifically deal with catalog maintenance. IEBCOPY can be used for managing catalogs, but this option does not include the utility that specifically deals with catalog maintenance. Therefore, this option is incorrect.
The correct answer is D) IEHLIST, IEHPROGM. This option is correct because both IEHLIST and IEHPROGM are system utilities that can be used to maintain and manage catalogs.
