ITPEC IP April 2022 Question 20
ITPEC IP April 2022 — Question 20 of 100
The total backup time is 50 minutes. From Monday through Thursday, 1,000 modified files are copied each day: 4 × 1,000 × 3 MB = 12,000 MB. On Friday all 6,000 files are copied: 6,000 × 3 MB = 18,000 MB. The weekly total is therefore 30,000 MB. At 10 MB/s, the time is 30,000 ÷ 10 = 3,000 seconds, which is 3,000 ÷ 60 = 50 minutes.
Answer (c)
Why not others:
- 25 omits half of the required data
- 35 does not include the four daily incremental backups correctly
- 150 is three times the calculated duration
Key rule: Add the data volumes of all incremental and full backups first, divide by transfer speed for seconds, then convert seconds to minutes.
