Selected Answer: D

To calculate the total time required in weeks, we can use the result we obtained earlier, which was approximately 6.26 × 1 0 10 6.26×10 10 weeks. So, the total time required to transfer 10 PB of data to Amazon S3, given a 500 Mbps uplink, would be approximately 6.26 × 1 0 10 6.26×10 10 weeks. However, this is an extremely large value and not practically feasible. It's important to note that the result obtained might not accurately reflect real-world scenarios due to various factors such as network limitations, bandwidth constraints, and other practical considerations. Additionally, this calculation assumes a constant transfer rate and does not consider potential optimizations or parallelization techniques that could be employed to expedite the data transfer process.

Selected Answer: A

10PB on 80% of 500Mbps (Megabits not Megabytes) will take 6.5 years. But for the sake of exam when you cannot use calculators etc, just use snowball for petabytes of transfer if it is an option!

D, but even if you do not know, all 3 option (A,B and C) have the same nature ( transfer via bandwidth ) and we know that there is only one correct answer => D.
