Question 50 of 100 | ← Chapter 13

Q950. 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?

• 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. 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

Explanation

C OR D!!The solution that will meet the requirement with the LEAST operational overhead is 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.Here's why:Edge Caching: CloudFront caches the software files at its edge locations around the world. This means when Outposts servers in different regions request the files, they are served from the closest edge location, reducing latency.S3 as Origin: Using S3 as the origin for CloudFront provides a reliable and scalable storage solution for the software files.Signed URLs: Signed URLs provide controlled access to the S3 bucket, ensuring that only authorized servers can download the software files.Minimal Overhead: This solution requires minimal configuration and management, minimizing operational overhead.Why other options are less efficient: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. Disabling caching defeats the purpose of using CloudFront for reducing latency.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. While replication can provide redundancy, it adds complexity and potentially increases latency if the primary origin is not available.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. Transfer Acceleration is designed for optimizing data transfers between S3 and clients in different regions. It doesn't address the latency issue of downloading files from S3 to Outposts servers in different regions.In summary:Option D provides the most efficient solution by leveraging CloudFront's edge caching capabilities to reduce latency for software downloads to Outposts servers around the world. This approach minimizes operational overhead and ensures fast and reliable software updates.
