AWS Certified Solutions Architect – Associate (SAA-C03) — Question 905

A company that is in the ap-northeast-1 Region has a fleet of thousands of AWS Outposts servers. The company has deployed the servers at remote locations around the world. All the servers regularly download new software versions that consist of 100 files. There is significant latency before all servers run the new software versions.

The company must reduce the deployment latency for new software versions.

Which solution will meet this requirement with the LEAST operational overhead?

Answer options

• A. Create an Amazon S3 bucket in ap-northeast-1. Set up an Amazon CloudFront distribution in ap-northeast-1 that includes a CachingDisabled cache policy. Configure the S3 bucket as the origin. Download the software by using signed URLs.
• B. Create an Amazon S3 bucket in ap-northeast-1. Create a second S3 bucket in the us-east-1 Region. Configure replication between the buckets. Set up an Amazon CloudFront distribution that uses ap-northeast-1 as the primary origin and us-east-1 as the secondary origin. Download the software by using signed URLs.
• C. Create an Amazon S3 bucket in ap-northeast-1. Configure Amazon S3 Transfer Acceleration. Download the software by using the S3 Transfer Acceleration endpoint.
• D. Create an Amazon S3 bucket in ap-northeast-1. Set up an Amazon CloudFront distribution. Configure the S3 bucket as the origin. Download the software by using signed URLs.

Correct answer: D

Explanation

Amazon CloudFront caches content at edge locations worldwide, which drastically reduces latency for globally distributed AWS Outposts servers downloading identical software update files. Using signed URLs ensures secure access to the files stored in the S3 bucket origin with minimal operational overhead. Option A disables caching, Option B introduces unnecessary cross-region replication overhead, and Option C is optimized for uploading to S3 rather than distributing large numbers of downloads globally.
