Refer to the exhibit.

A customer starts a test running on a thick LUN. The test generates random 4 kB I/Os with a
R/W ratio of 2:1. A VNX Snapshot is started on the thick LUN at 09:37. The customer notes
a decrease in LUN performance and asks for an explanation.
Which explanation is correct?

A.
New writes are redirected to slices outside of the thick LUN area.

B.
The read/write ratio changes once a VNX Snapshot is started on a LUN.

C.
Write coalescing causes the physical disks to perform longer seeks.

D.
Prefetching causes the physical disks to perform fewer seeks.
