Answer: Turn on S3 Transfer Acceleration on the destination S3 bucket. Use multipart uploads to directly upload site data to the destination S3 bucket.
## Explanation **Correct Answer: A** **Why Option A is correct:** 1. **S3 Transfer Acceleration** uses Amazon CloudFront's globally distributed edge locations to accelerate data transfers to S3 buckets. This is ideal for global data aggregation scenarios where data needs to be uploaded from multiple locations worldwide to a single S3 bucket. 2. **Multipart uploads** allow parallel uploading of large files (500 GB daily per site), which improves transfer speed and reliability. 3. This solution minimizes operational complexity because: - No intermediate storage or processing steps are required - No manual device management (unlike Snowball) - No complex replication setup or EC2 instance management - Direct upload to the destination bucket **Why Option B is incorrect:** - While S3 Cross-Region Replication can copy data between regions, it adds complexity with multiple buckets and replication rules. - Requires data to be uploaded to intermediate regional buckets first, then replicated, then deleted - adding operational overhead. - Not the fastest solution since it involves two transfer steps. **Why Option C is incorrect:** - AWS Snowball Edge is designed for offline data transfer when internet connectivity is poor or bandwidth is limited. - The scenario states each site has a "high-speed Internet connection," making Snowball unnecessary and overly complex. - Requires physical device management, scheduling, and shipping - adding significant operational complexity. **Why Option D is incorrect:** - This is the most complex solution involving EC2 instances, EBS volumes, snapshots, and volume restoration. - Multiple steps and services increase operational complexity significantly. - Not the fastest approach due to multiple intermediate steps. **Key AWS Services Understanding:** - **S3 Transfer Acceleration**: Optimizes transfer speed for long-distance uploads to S3 by routing through CloudFront edge locations. - **Multipart Uploads**: Enables parallel uploads of large objects for better throughput and reliability. - The combination provides the fastest, simplest solution for aggregating large volumes of data from global locations to a single S3 bucket.

A company collects data for temperature, humidity, and atmospheric pressure in cities across multiple continents. The average volume of data that the company collects from each site daily is 500 GB. Each site has a high-speed Internet connection. The company wants to aggregate the data from all these global sites as quickly as possible in a single Amazon S3 bucket. The solution must minimize operational complexity.
Which solution meets these requirements?
A
Turn on S3 Transfer Acceleration on the destination S3 bucket. Use multipart uploads to directly upload site data to the destination S3 bucket.
B
Upload the data from each site to an S3 bucket in the closest Region. Use S3 Cross-Region Replication to copy objects to the destination S3 bucket. Then remove the data from the origin S3 bucket.
C
Schedule AWS Snowball Edge Storage Optimized device jobs daily to transfer data from each site to the closest Region. Use S3 Cross-Region Replication to copy objects to the destination S3 bucket.
D
Upload the data from each site to an Amazon EC2 instance in the closest Region. Store the data in an Amazon Elastic Block Store (Amazon EBS) volume. At regular intervals, take an EBS snapshot and copy it to the Region that contains the destination S3 bucket. Restore the EBS volume in that Region.
