ITPEC IP October 2020 Question 20
ITPEC IP October 2020 — Question 20 of 100
The weekly backup time is 50 minutes. Monday through Thursday copy 4 × 1,000 × 3 = 12,000 MB. Friday's full backup copies 6,000 × 3 = 18,000 MB. The total 30,000 MB at 10 MB/s takes 3,000 seconds, or 50 minutes.
Answer (c)
Why not others:
- 25 minutes counts only the Friday full backup
- 35 minutes does not include the stated daily and full volumes correctly
- 150 confuses the total data or unit conversion
Key rule: Sum every incremental and full backup volume first, divide by transfer speed, and finally convert seconds to minutes.
