How many extents are possible for a sequential file?
-
20 extents on a volume for a sequential file
-
26 extents on a volume for a sequential file
-
14 extents on a volume for a sequential file
-
16 extents on a volume for a sequential file
In z/OS DFSMS, a standard sequential dataset (non-extended format) is limited to a maximum of 16 extents per volume. If a sequential file needs to grow beyond 16 extents, it must span across multiple volumes or use extended format.
To answer this question, we need to understand what an extent is in the context of a sequential file.
In a sequential file, data is stored in blocks or units called extents. An extent is a contiguous section of storage space on a storage volume. When a sequential file is created, it can be allocated multiple extents to store its data.
The correct answer is D) 16 extents on a volume for a sequential file. This means that a sequential file can have up to 16 extents allocated on a storage volume to store its data.
