ADRDSSU Utility is used
-
To reduce free space fragmentation
-
To copy or move Datasets from one DASD to another
-
All of the above
-
None of the above
To answer this question, the user needs to know what ADRDSSU Utility is used for.
The ADRDSSU Utility is a tool used for backup, restore, and copying datasets. It can be used to copy or move datasets from one DASD to another, and can also be used to reduce free space fragmentation.
Therefore, the correct answer is:
C. All of the above
"All of the above" is correct. ADRDSSU is the program name behind DFSMSdss, the z/OS data-set/volume movement and space-management utility. It performs DUMP/RESTORE and COPY functions to move or copy data sets (and whole volumes) between DASD devices, and it also provides a DEFRAG/COMPRESS-type function that consolidates free space and reduces free-space fragmentation on a volume. Since both listed capabilities (copying/moving data sets, and reducing free-space fragmentation) are genuine ADRDSSU functions, "All of the above" correctly captures its scope rather than either function alone.
