The correct answer is C. About 100 days. To calculate transfer time: 100 TB = 100 × 1,024 GB = 102,400 GB = 819,200 Gb (gigabits). At 100 Mbps = 0.1 Gbps, time = 819,200 Gb ÷ 0.1 Gbps = 8,192,000 seconds. Dividing by 86,400 seconds/day ≈ 94.8 days, which rounds to approximately 100 days. This illustrates why Google…
Question
A startup client of yours does offline data processing for a few of its clients. They are mi-grating their applications and the associated data to Google Cloud. They have 100TB of data to move. They presently have a very small private data center setup connected to a local internet provider. The maximum bandwidth they are able to get is 100Mbps. How long will it take them to transfer the data over the internet if the transfer goes smoothly?
Options
- About 12 days.
- BAbout 2 years.
- CAbout 100 days.
- DAbout 24 hours.

Explanation
To calculate transfer time: 100 TB = 100 × 1,024 GB = 102,400 GB = 819,200 Gb (gigabits). At 100 Mbps = 0.1 Gbps, time = 819,200 Gb ÷ 0.1 Gbps = 8,192,000 seconds. Dividing by 86,400 seconds/day ≈ 94.8 days, which rounds to approximately 100 days. This illustrates why Google offers Transfer Appliance for large datasets - internet transfer at typical bandwidth speeds is impractical for hundreds of terabytes. 'About 24 hours' (D) would require ~9.5 Gbps. 'About 12 days' (A) would require ~800 Mbps.
