23.A system administrator is trying to develop a logical volume strategy based on
availability, performance, and cost that is appropriate to the site. Which of the
following statements is not true?
A. Performance is the average speed at which data is accessed. Policies such as write-verify and mirroring add to system processing load; and thus degrade performance.
B. Specifying mirrored logical volumes with a parallel-scheduling policy may improve I/O read-operation performance because multiple copies allow the system to direct the read operation to the copy that can be most quickly accessed.
C. The parallel-scheduling policy starts the write operation for all the physical partitions in a logical partition at the same time. When the write operation to a partition that takes the longest to finish is complete, the write operation is considered complete.
D. The sequential-scheduling policy performs writes to multiple copies or mirrors in order. In sequential scheduling; the physical partitions are written to in sequence. The system does not wait for the write operation to complete before starting the write operation for the next one.
