ITPEC IP April 2025 Question 19
ITPEC IP April 2025 — Question 19 of 100
50 minutes — add four daily incremental backups and Friday's full backup.
From Monday through Thursday, each backup copies 1,000 × 3 = 3,000 MB. At 10 MB/s, that takes 300 seconds, or 5 minutes per day, totaling 20 minutes. On Friday all 6,000 × 3 = 18,000 MB are copied, taking 1,800 seconds, or 30 minutes. The weekly total is 20 + 30 = 50 minutes.
Answer (c)
Why not others:
- (a) 25 counts five incremental backups and omits Friday's full backup
- (b) 35 adds just one incremental backup to the full backup
- (d) 150 misapplies the transfer rate or time conversion
Key rule: Calculate the data volume for each backup type, divide by throughput, convert units, and only then sum the scheduled runs.
