Hello,

I am struggling with some of the questions in the practice E20-324 tests, I have been uisng the video based course. Can anyone help and explain how to calculate the answer of this example please?

A customer wants to add a SnapView snapshot to a 600 GiB LUN. Captured data show that the LUN has an access rate of 1000 IOPs with a read/write ratio of 4:1, and 8 KiB IOs. What is the expected initial bandwidth at which data chunks will be written into the Reserved LUN Pool?

A. 12.500 MiB/s

B. 1.563 MiB/s

C. 6.250 MiB/s

D. 25.000 MiB/s

Many thanks
