Question 20 of 100 | ← Chapter 12

Q820. A data analytics company has 80 offices that are distributed globally. Each office hosts 1 PB of data and has between 1 and 2 Gbps of internet bandwidth.The company needs to perform a one-time migration of a large amount of data from its offices to Amazon S3. The company must complete the migration within 4 weeks.Which solution will meet these requirements MOST cost-effectively?

Correct Answer: B. Use multiple AWS Snowball Edge storage-optimized devices to store and transfer the data to Amazon S3.

Explanation

The most cost-effective solution to meet the requirements would be option B: Use multiple AWS Snowball Edge storage-optimized devices to store and transfer the data to Amazon S3.AWS Snowball Edge is a data transfer and edge computing device that can be used to securely and efficiently transfer large amounts of data to and from AWS. The storage-optimized variant of Snowball Edge is designed specifically for data migration and can handle up to 80 TB of data per device.In this scenario, with 80 offices each hosting 1 PB of data, using multiple Snowball Edge devices would be a practical and cost-effective approach. The data can be transferred to the Snowball Edge devices at each office, and then the devices can be shipped to an AWS region where the data is loaded into Amazon S3. This approach eliminates the need for establishing new high-bandwidth connections or using specialized data transfer services like Snowmobile.By utilizing Snowball Edge, the company can take advantage of the cost-effectiveness of shipping and transferring data in physical devices rather than relying solely on internet bandwidth. It also provides a scalable solution as multiple Snowball Edge devices can be used simultaneously to parallelize the data transfer process, reducing the overall migration time.Option A, establishing new 10 Gbps AWS Direct Connect connections to each office, may be costly and time-consuming to set up across multiple locations.Option C, using an AWS Snowmobile, is typically used for exabyte-scale data transfers and is not the most cost-effective solution for a one-time migration of 80 PB of data.Option D, using an AWS Storage Gateway Volume Gateway, is more suitable for ongoing data synchronization between on-premises and cloud storage rather than a one-time migration of large amounts of data.Therefore, option B is the most cost-effective solution for the one-time migration of a large amount of data from the company's offices to Amazon S3.
