How many extents are possible for a VSAM file
-
123 extents for a VSAM file.
-
113 extents for a VSAM file.
-
133 extents for a VSAM file.
-
143 extents for a VSAM file.
VSAM (Virtual Storage Access Method) files allow a maximum of 123 extents. Extents are additional allocations of disk space when the primary allocation is filled. This is a system limitation for VSAM datasets. The other values (113, 133, 143) are incorrect VSAM extent limits.
To answer this question, we need to understand the concept of extents in VSAM (Virtual Storage Access Method) files.
In VSAM, a file is divided into multiple extents. An extent is a contiguous block of storage allocated to a file. Each extent can contain a certain number of records.
The maximum number of extents that can be allocated to a VSAM file depends on the size of each extent and the total storage available.
Based on the information provided, the correct answer is: Option A) 123 extents for a VSAM file.
This option is correct because it states that a VSAM file can have 123 extents.
