B- Three

C- Two

D- One

Explanation

Click "Show Answer" to see the explanation here

Correct Answer:

One is correct.

70 percent of 4TB is 2.8TB; 25 percent of 2.8TB is 0.7TB each year, or 1.4TB over two years. Current used space of 2.8TB plus 1.4TB planned growth equals 4.2TB, and the current disk is only 4TB, so one more 4TB disk is needed.
