Question 43 of 100 | ← Chapter 10

Q643. A company will migrate 10 PB of data to Amazon S3 in 6 weeks.The current data center has a 500 Mbps uplink to the internet. Other on-premises applications share the uplink. The company can use 80% of the internet bandwidth for this one-time migration task.Which solution will meet these requirements?

Correct Answer: D. Order multiple AWS Snowball devices. Copy the data to the devices. Send the devices to AWS to copy the data to Amazon S3

Explanation

To meet the requirements of migrating 10 PB of data to Amazon S3 in 6 weeks, considering the limited uplink bandwidth and the need to utilize 80% of the internet bandwidth, the most suitable solution is:D. Order multiple AWS Snowball devices, copy the data to the devices, and send the devices to AWS to copy the data to Amazon S3.AWS Snowball is a service designed specifically for large-scale data migrations where transferring data over the internet is not feasible or efficient. By ordering multiple AWS Snowball devices, you can physically transfer the data onto the devices at the data center, taking advantage of the higher data transfer rates available locally. Once the data is loaded onto the Snowball devices, you can securely ship them to AWS, where AWS will copy the data to Amazon S3 on your behalf. This approach significantly reduces the time required for the migration and minimizes the impact on the limited uplink bandwidth.Option A is not the best choice for this scenario:A. Configuring AWS DataSync to migrate the data to Amazon S3 might be a suitable option for ongoing data synchronization, but it may not be the most efficient solution for a one-time migration of such a large volume of data. It would still rely on the limited uplink bandwidth and might take significantly longer than the desired timeframe.Option B is not the best choice either:B. Using rsync to transfer the data directly to Amazon S3 would still rely on the limited uplink bandwidth, which could result in a much longer migration time. It may not be feasible to complete the migration within the given 6-week timeframe.Option C is not the best choice either:C. Using the AWS CLI and multiple copy processes to send the data directly to Amazon S3 would also rely on the limited uplink bandwidth, which might not be sufficient to complete the migration within the desired timeframe.Therefore, option D is the most appropriate solution for migrating 10 PB of data to Amazon S3 within the given timeframe, considering the limited uplink bandwidth and the need to utilize 80% of the internet bandwidth.
