This SAA-C03 practice question tests your understanding of design high-performing architectures. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. A key principle to apply: s3 Transfer Acceleration uses AWS Edge Locations to speed up uploads.. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A latency-sensitive video platform uploads large files to S3 from users around the world. Which two features can improve upload performance? The architecture review board prefers a managed AWS-native control.
S3 Object Lock
Why wrong: Object Lock enforces retention and does not speed uploads.
S3 Transfer Acceleration
Transfer Acceleration uses optimized edge paths into AWS for long-distance S3 transfers.
S3 multipart upload
Multipart upload parallelizes large object upload parts and improves reliability.
S3 Inventory
Why wrong: Inventory reports object metadata and does not accelerate transfers.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
S3 Transfer Acceleration
S3 Transfer Acceleration (B) uses AWS edge locations to accelerate uploads over long distances by routing traffic through the AWS global network, reducing latency and packet loss compared to the public internet. Multipart upload (C) improves performance by splitting large files into smaller parts that can be uploaded in parallel, increasing throughput and allowing retries of individual parts without restarting the entire upload.
Key principle: S3 Transfer Acceleration uses AWS Edge Locations to speed up uploads.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
S3 Object Lock
Why it's wrong here
Object Lock enforces retention and does not speed uploads.
S3 Transfer Acceleration
Why this is correct
Transfer Acceleration uses optimized edge paths into AWS for long-distance S3 transfers.
Related concept
S3 Transfer Acceleration uses AWS Edge Locations to speed up uploads.
S3 multipart upload
Why this is correct
Multipart upload parallelizes large object upload parts and improves reliability.
Related concept
S3 Transfer Acceleration uses AWS Edge Locations to speed up uploads.
S3 Inventory
Why it's wrong here
Inventory reports object metadata and does not accelerate transfers.
Common exam traps
The trap here is that candidates may confuse S3 Transfer Acceleration with CloudFront or think multipart upload is only for reliability, not performance, while overlooking that both features are managed AWS-native controls that directly address latency and throughput for large file uploads.
Detailed technical explanation
S3 Transfer Acceleration leverages TCP optimizations and persistent connections over AWS's private backbone, often reducing upload times by 50-80% for cross-region transfers. Multipart upload is recommended for objects larger than 100 MB and required for objects over 5 GB; each part can be uploaded concurrently, and failed parts are retried independently, which is critical for large files over unreliable networks.
Key takeaway
S3 Transfer Acceleration uses AWS Edge Locations to speed up uploads.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
