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

Using Amazon CloudFront as a global content delivery network (CDN) caches software updates closer to the remote Outposts servers at AWS edge locations. This significantly reduces latency compared to downloading files directly from S3. ✔ Global Acceleration – CloudFront caches the software in edge locations worldwide, reducing latency for remote locations. ✔ Efficient Distribution – Servers in different regions fetch files from the closest CloudFront edge cache instead of always pulling from ap-northeast-1. ✔ Signed URLs for Security – Ensures only authorized servers can download the software. ✔ Low Operational Overhead – No need for replication, manual distribution, or complex networking setups.

Including "global" makes CloudFront stand out as the obvious choice. But S3 global acceleration requires the least operational overhead while also assisting with latency issues. The mention of hundreds of files also points towards s3 acceleration.

IMO answer is C. A is out because disabling caching, it involves higher latency than C B is out because it doesn't meet the requirements: adds complexity without significant latency reduction D meets the requirements but it requires more operational overhead than C

A - CachingDisabled is the polar opposite of our goal. B - CloudFront with dual-region origins adds unnecessary complexity without significant latency reduction. C - Faster upload/download speeds compared to direct S3 access, but the distribution latency is still there! D - Looks good. Just one small thing: files may take a little longer to propagate to edge locations initially, but this can be mitigated by configuring an appropriate cache invalidation policy. Once cached at edge locations, subsequent downloads would be much faster.

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.
