CompTIA Server+ (SK0-004) — Question 2

A technician performs monthly backups on a file server to a NAS device that can hold 1TB of data. The size of the monthly backups has been as follows:

Month 1 = 50GB -

Month 2 = 65GB -

Month 3 = 80GB -
Starting with Month 1, based on the current rate of growth, in how many months will the NAS run out of available storage space?

Answer options

• A. 4
• B. 5
• C. 9
• D. 11

Correct answer: C

Explanation

The monthly backups are increasing by 15GB each month on average (Month 2 - Month 1 = 15GB, Month 3 - Month 2 = 15GB). Starting from 50GB, the total after 9 months would be approximately 50GB + (8 months * 15GB) = 170GB, which would fill the NAS, making 9 months the correct answer. The other options do not account for the correct growth rate and timing.
