AWS Certified Solutions Architect – Associate (SAA-C02) — Question 479

A company used an AWS Direct Connect connection to copy 1 PB of data from a colocation facility to an Amazon S3 bucket in the us-east-1 Region. The company now wants to copy the data to another S3 bucket in the us-west-2 Region.
Which solution will meet this requirement?

Answer options

• A. Use an AWS Snowball Edge Storage Optimized device to copy the data from the colocation facility to us-west-2.
• B. Use the S3 console to copy the data from the source S3 bucket to the target S3 bucket.
• C. Use S3 Transfer Acceleration and the S3 copy-object command to copy the data from the source S3 bucket to the target S3 bucket.
• D. Add an S3 Cross-Region Replication configuration to copy the data from the source S3 bucket to the target S3 bucket.

Correct answer: D

Explanation

S3 Cross-Region Replication (CRR), combined with S3 Batch Replication for existing objects, is the most efficient and scalable way to copy 1 PB of data between S3 buckets in different regions. Using the S3 console or individual S3 copy-object commands is impractical for petabyte-scale data due to transfer limits and management overhead. Re-transferring the data from the colocation facility using AWS Snowball Edge is unnecessary and inefficient since the data is already hosted within AWS.
