A Company Is Running a High-User-Volume Media-Sharing Application on Premises

question 650

Multiple Choice

A company is running a high-user-volume media-sharing application on premises. It currently hosts about 400 TB of data with millions of video files. The company is migrating this application to AWS to improve reliability and reduce costs. The Solutions Architecture team plans to store the videos in an Amazon S3 bucket and use Amazon CloudFront to distribute videos to users. The company needs to migrate this application to AWS within 10 days with the least amount of downtime possible. The company currently has 1 Gbps connectivity to the Internet with 30 percent free capacity. Which of the following solutions would enable the company to migrate the workload to AWS and meet all of the requirements?

• A) Use a multi-part upload in Amazon S3 client to parallel-upload the data to the Amazon S3 bucket over the Internet. Use the throttling feature to ensure that the Amazon S3 client does not use more than 30 percent of available Internet capacity.
• B) Request an AWS Snowmobile with 1 PB capacity to be delivered to the data center. Load the data into Snowmobile and send it back to have AWS download that data to the Amazon S3 bucket. Sync the new data that was generated while migration was in flight.
• C) Use an Amazon S3 client to transfer data from the data center to the Amazon S3 bucket over the Internet. Use the throttling feature to ensure the Amazon S3 client does not use more than 30 percent of available Internet capacity.
• D) Request multiple AWS Snowball devices to be delivered to the data center. Load the data concurrently into these devices and send it back. Have AWS download that data to the Amazon S3 bucket. Sync the new data that was generated while migration was in flight.
