Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 1 discussion

Keyword: From GLOBAL sites as quickly as possible in a SINGLE S3 bucket. Minimize operational complexity A. is correct because S3 Transfer Acceleration is support for high speed transfer in Edge location and you can upload it immediately. Also with multipart uploads your big file can be uploaded in parallel. B, C, D. is not minimize operational and fast when compare to answer A

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

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.

the simplest way

Eliminating other options, Option A is feasible and cost efficient.

A for sure

chon A

S3 Acceleration is more proper with less operation in this case

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.

I think that should be option A

S3 bucket

Hi All, I have gone through the exam today and it was bit tough, none of the questions in the exam came from examtopics, i have gone mostly around 150 questions. The questions we go through here are quite easy compared to actual ones. i just suggest everyone to go through some youtube ( sthithapragna) videos as well apart from examtopics. YT videos were found quite accurate to the exams which i have attempted today.(1/13/2025).Hope this review helps everyone.

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

Amazon S3 Transfer Acceleration meets the requirements by ensuring fast, secure, and simple global data uploads with minimal operational overhead.

Transfer Aceleration com multpart upload é a opção menos complexa

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.
