Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 971 discussion

By setting up a CloudFront distribution with the S3 bucket as the origin, the software versions can be cached at edge locations close to the remote AWS Outposts servers. This reduces the latency of downloading new software versions because the servers can access the content from the nearest CloudFront edge location instead of downloading it directly from the S3 bucket in the ap-northeast-1 Region. About option C: S3 Transfer Acceleration optimizes the upload and download of files to S3 by routing through optimized network paths. However, it is primarily designed to improve performance when transferring data over long distances to S3 (uploads). It does not provide the same level of global caching and latency reduction as CloudFront for large-scale distribution.

Option C is correct. Option D brings additional overhead in terms of setting up, so opted out. Also from google : If you want to download software quickly from a large distance, you should generally use S3 Transfer Acceleration to download from your S3 bucket, as it leverages Amazon's global edge network to significantly speed up long-distance data transfers, making it ideal for large file downloads across continents; while CloudFront is better suited for delivering smaller content like website assets to users globally, where faster response times and caching are critical

C : all other options use CloudFront. CloudFront is a CDN, not needed for software download.

Should use S3 Transfer acceleration to avoid CF setup overhead. It will help with improving download speed

What about A? 1. Minimized operational overhead: This option provides the least operational overhead because it only requires setting up a single S3 bucket and a CloudFront distribution in the same region (ap-northeast-1), with a simple configuration to disable caching on the CloudFront distribution, ensuring fresh software updates are always delivered to Outposts servers. 2. Reduced latency: By using a CloudFront distribution with a CachingDisabled policy, the software updates will be delivered from the closest edge location to each Outpost server, significantly reducing latency due to geographical proximity. 3. Signed URLs for security: Using signed URLs ensures that only authorized users can access the software updates, enhancing security.

This approach leverages the global presence of CloudFront to minimize latency and simplifies the deployment process, reducing operational overhead.

S3 Transfer Acceleration speeds up uploads and downloads to S3 over long distances but does not provide the global caching benefits that CloudFront offers. CloudFront is more suitable for reducing latency when distributing content globally.

Correct answer is C Because for new software version we do not use Cloudfront,

The question asks for the solution with the least operational overhead. Option D has minimal setup and maintenance requirements, as CloudFront is a managed service that handles caching and distribution across the globe, reducing latency without requiring additional configurations or services.
