ITPEC IP October 2018 Question 22
ITPEC IP October 2018 — Question 22 of 100
The five backups require a total of 50 minutes. From Monday through Thursday, 1,000 files × 3 MB = 3,000 MB are copied each day. At 10 MB/s, that is 300 seconds or 5 minutes per day, totaling 20 minutes. Friday's full backup is 6,000 × 3 MB = 18,000 MB, requiring 1,800 seconds or 30 minutes.
Answer (c)
Why not others:
- 25 and 35 minutes omit part of the incremental or full-backup work
- 150 minutes results from an incorrect size, speed, or seconds-to-minutes conversion
Key rule: Add four daily incremental times and one full-backup time, converting seconds to minutes only after dividing data size by transfer speed.
