Fastest Way to Aggregate Global S3 Data into One Bucket?
Determine high-performing data ingestion and transformation solutions.
Determine high-performing and/or scalable network architectures.
Determine high-performing and/or scalable storage solutions.
Answer
Correct answer: A — enable S3 Transfer Acceleration on the destination bucket and upload each site's data directly with multipart uploads for the fastest, lowest-complexity global aggregation.
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?
Community Insight
The question tests long-distance S3 ingestion performance versus operational simplicity; the trap is choosing a regional staging bucket plus Cross-Region Replication, which adds a second copy step, cross-Region data-transfer charges, and replication configuration for no real gain when sites already have fast Internet.
For aggregating 500 GB per day from high-bandwidth sites on multiple continents into a single Amazon S3 bucket, S3 Transfer Acceleration combined with multipart uploads is the fastest, lowest-complexity design. Transfer Acceleration routes uploads over the CloudFront edge network to the destination bucket, while Cross-Region Replication staging (option B), Snowball devices (C), and EBS snapshot copying (D) all add hops, cost, and operational overhead.
Option B is the most tempting wrong pick: staging data in the nearest Region bucket and replicating it with S3 CRR appears geographically efficient, but it doubles the write work, adds replication rules, bucket permissions/IAM setup, and cross-Region transfer costs, violating both the 'as quickly as possible' and 'minimize operational complexity' requirements.

Why A is the best solution: S3 Transfer Acceleration uses Amazon CloudFront’s globally distributed edge locations to speed up uploads to an S3 bucket. This significantly improves upload times from geographically dispersed locations. Multipart Uploads are ideal for large files (like the 500 GB daily per site), allowing you to upload parts of a file in parallel, improving speed and reliability. This solution: Minimizes operational complexity (no need to manage replication or EC2 instances). Provides high performance by leveraging AWS’s optimized global infrastructure. Is a fully managed solution — no need for manual cleanup or orchestration.

Options B and D are technically possible solutions, but. B. The cost is high, the process is slower, and it is more complex. C. This option is not feasible. You would need to purchase Snowball devices, wait for them to arrive, upload the 500GB of data, and then ship them back. This process is not practical for daily use. Snowball devices are designed for one-time uploads of terabytes of data, not for routine or smaller-scale transfers. D. Using EC2 instances, EBS volumes, and cross-Region snapshots is also not ideal. The cost is significantly higher, and the process is overly complex for this scenario.

AWS Global Accelerator is a networking service that improves the performance and availability of your applications by leveraging the global infrastructure of AWS. It provides two key benefits: Improved Performance: Global Accelerator uses the AWS global network to direct user traffic to the nearest AWS Region or endpoint, reducing latency. It supports TCP and UDP traffic and can significantly enhance the performance of latency-sensitive applications, such as gaming, IoT, or streaming. Increased Availability: Global Accelerator provides automatic failover between endpoints in multiple AWS Regions or Availability Zones. If one endpoint becomes unavailable, the traffic is rerouted to the next best endpoint.

Correct Answer: A: S3 Transfer Acceleration with multipart uploads is the most efficient solution due to high-speed transfer, minimal operational complexity and large data transfer. Wrong Options: B. Increases operational complexity with additional steps (cross-region replication and data deletion). Not necessary since high-speed connections are available at each site. C. Unnecessary use of physical Snowball devices for data transfer when high-speed internet connections are available on-site. D. More complex solution with unnecessary steps (EC2 instances, EBS volumes, snapshots). Direct S3 upload with Transfer Acceleration is simpler and faster.

S3 Transfer Acceleration service itself will make use of globally distributed edge locations in Amazon CloudFront. So this has similar meaning as "Upload the data from each site to an S3 bucket in the closest Region" of option B. Moreover, option A is a single step action (local --> destination, middle step handled by AWS), while B is 2-step action (local --> closest region bucket --> destination), so option A shall be more appropriate.
Buruguduystunstugudunstuy
👍 1
Option D involves uploading the data from each site to an EC2 instance in the closest Region and storing it in an EBS volume. At regular intervals, you would take an EBS snapshot and copy it to the Region that contains the destination S3 bucket. This option may not be the most efficient solution, as it would require transferring data over the internet multiple times and may require more operational complexity to set up and manage the EC2 instances and EBS volumes. Overall, Option B is a simple and efficient solution for aggregating data from multiple global sites in a single S3 bucket.
Guru4Cloud
👍 2
Selected: B
Explanation: Option B suggests uploading the data from each site to an S3 bucket in the closest Region. This ensures that the data is transferred quickly over high-speed Internet connections. By using S3 Cross-Region Replication, the objects can be automatically copied to the destination S3 bucket, allowing for easy aggregation. Once the data is successfully replicated, it can be removed from the origin S3 bucket to minimize storage costs and reduce complexity. Option A is not the best choice because it only focuses on optimizing the upload to the destination S3 bucket by using S3 Transfer Acceleration and multipart uploads. However, it doesn't address the requirement of aggregating data from multiple sites.

But B requires manual intervention (removal from original bucket), that does meet the 'minimize operational complexity' requirement.
pentium75

A specifically mentions "multipart upload", but the stem says nothing about large files. We have "sites" that collect a lot of sensor data. Wouldn't C be an option? Snowball Edge is tied to a region, so it can't upload directly to the central bucket. Copying the files onto Snowball Edge, then let Snowball Edge upload them to a bucket in its own region from where they would be replicated to the central bucket. This would meet the requirement of minimizing operational overhead. (Options B and D are clearly out as they require manual intervention.)

The Snowball family is used for petabyte-scale migrations so using Snowball is overkill. You can simply use transfer acceleration AND multi-part uploads to speed up S3 uploads as they are already features of the service.

A is the best answer, especially going with multi-part upload, transferring the data to the destination bucket using transfer accelerator.

A. Despite this option can be valid, it implies a bit of operational overhead compared with other options. Additionally, there is no need to aggregate that change to the existing architecture because we are already working in S3, and using other storage services incurs unnecessary costs. B. To collect the logs, we use CloudTrail over CloudWatch. Running SQL queries from the Amazon CloudWatch console is not recommended for this use case, since it is more used for filtering. C. Athena integrates seamlessly with S3 and allows you to run simple SQL queries in no time. When working with Apache Spark or with SQL in S3, using this service is the best option. D. This option incurs elevated operational overhead. Glue is not used to catalog the logs. Analyzing logs with Spark on an EMR cluster is very common, but you can do it faster with the Athena service integrated with S3 directly.

General line: Collect huge amount of the files across multiple continents Conditions: High speed Internet connectivity Task: aggregate the data from all in a single S3 bucket Requirements: as quick as possible, minimize operational complexity Correct answer A: S3 Transfer Acceleration because: - ideally works with objects for long-distance transfer (uses Edge Locations) - can speed up content transfers to and from S3 as much as 50-500% - use cases: mobile & web application uploads and downloads, distributed office transfers, data exchange with trusted partners. Generally for sharing of large data sets between companies, customers can set up special access to their S3 buckets with accelerated uploads to speed data exchanges and the pace of innovation. B - about disaster recovery C - about transferring data between your local environment and the AWS Cloud D - about disaster recovery

C, we DO have a "local environment" (a "site") that collect data, and THAT data must go to "the AWS cloud". Why not C? The stem says nothing about large objects, which would be a requirement for the "multipart upload" that is mentioned.

C wouldn't apply because it increases complexity. No if during the investigative process you found that Snowball was present then you could discuss this. But chances are if snowball is present then transfer rate isn't an issue in the first place. The same could be said for Private Link connections per site.

Correct answer is A that is S3 Transfer Acceleration considering the points like 1) Having high internet speed 2) Need to transfer GBs of data regularly from different cities in different continents 3) With minimum operational cost. It is basically used when you have very fast internet service and collecting data from all over the world in GB or TB on regular basis. It first transfer the data to nearest Edge location and then this data is transferred to the target S3 bucket over an optimized network path.

Expert Analysis
Why the Answer Is Correct
Option A turns on S3 Transfer Acceleration on the destination bucket and uploads directly from each site with multipart uploads. Transfer Acceleration uses CloudFront edge locations so that long-distance traffic travels over AWS's optimized backbone instead of the public Internet, typically boosting 500 GB-scale transfers over continents by roughly 50–500%. Multipart upload lets each site's large daily payload upload in parallel parts and resume on failure, which shortens the total transfer window further. This is a single-step, fully managed path from each site straight into the one destination bucket, so it also satisfies the 'minimize operational complexity' constraint with no extra buckets, replication rules, or hardware logistics.Why the Other Options Are Wrong
Option B requires a second regional bucket per site, S3 Cross-Region Replication with versioning enabled, lifecycle/cleanup of the origin objects, and pays cross-Region data-transfer charges — three moving parts for data that could have gone straight to the destination. Option C schedules daily AWS Snowball Edge Storage Optimized devices, which are designed for offline/limited-connectivity or multi-terabyte offline transfers; since every site has a high-speed Internet connection, daily device logistics and shipping are far slower and operationally heavy. Option D routes data through EC2 and EBS, then snapshots and copies volumes across Regions before restoring them to move data into S3 — an indirect pipeline with snapshot copy windows and restore delays that is neither fast nor simple. As thewalker noted, "Cross region replication attracts extra costs to transfer data across regions" while pentium75's concern about multipart upload misses that 500 GB/day sites routinely push multi-gigabyte files, and AWS supports multipart for objects well above the minimum threshold.Community Comment Notes
PhucVuu's top-voted explanation matches the verdict, pointing to "S3 Transfer Acceleration is support for high speed transfer in Edge location" plus parallel multipart uploads for large files. goodmail correctly observes that Transfer Acceleration's edge locations behave like option B's nearest-Region upload but that "option A is a single step action" while B is two steps. sandhyaejji cites the official 50–500% long-distance speedup figure, and Naneyerocky quotes that Transfer Acceleration "is designed to optimize transfer speeds from across the world into S3 buckets." Buruguduystunstugudunstu argued for B on latency grounds, but that reasoning ignores replication overhead and cost; pentium75's C vote is unsupported because each site has high-speed Internet, which eliminates the Snowball use case entirely.Official Reference
Exam Strategy
On SAA-C03 design questions, scan for the qualifiers 'high-speed Internet connection' and 'minimize operational complexity' — they signal a direct, fully managed path (Transfer Acceleration, direct upload) rather than staging, replication, or appliance-based transfers. Eliminate any option that introduces a second storage tier, a copy job, or manual logistics unless connectivity or scale genuinely requires it.
Frequently Asked Questions
Why is S3 Cross-Region Replication (option B) not the best choice here?
CRR needs a staging bucket per site, versioning, replication rules, and origin cleanup, and it charges cross-Region transfer fees. Transfer Acceleration gets data to the destination bucket in one hop using AWS's edge network.
Does multipart upload require very large objects to be valid in option A?
Multipart upload works for any object above the minimum part sizes and is recommended for large or parallel uploads. Sites pushing 500 GB daily routinely exceed these thresholds, so it is a valid performance booster.
