To answer this question, we need to understand the concept of control areas in VSAM datasets.
Control areas are logical divisions within a VSAM dataset that contain data records. Each control area has a fixed size.
The given question asks for the maximum and minimum sizes of any control area in VSAM datasets.
Option A) Minimum Size: 1 track Maximum Size: 10 cylinders
Option B) Minimum Size: 10 tracks Maximum Size: 1 cylinder
Option C) Minimum Size: 0 tracks Maximum Size: 1 track
Option D) Minimum Size: 1 track Maximum Size: 1 cylinder
Let's analyze each option:
Option A) Minimum Size: 1 track Maximum Size: 10 cylinders - This option is incorrect. The minimum size of a control area cannot be 1 track, and the maximum size cannot be 10 cylinders.
Option B) Minimum Size: 10 tracks Maximum Size: 1 cylinder - This option is incorrect. The minimum size of a control area cannot be 10 tracks, and the maximum size cannot be 1 cylinder.
Option C) Minimum Size: 0 tracks Maximum Size: 1 track - This option is incorrect. The minimum size of a control area cannot be 0 tracks.
Option D) Minimum Size: 1 track Maximum Size: 1 cylinder - This option is correct. The minimum size of a control area is 1 track, and the maximum size is 1 cylinder.
Therefore, the correct answer is Option D. The minimum size of any control area is 1 track, and the maximum size is 1 cylinder.
