Question 7 of 100 | ← Chapter 11

Q707. A company has a new mobile app Anywhere in the world, users can see local news on topics they choose. Users also can post photos and videos from inside the app. Users access content often in the first minutes after the content is posted. New content quickly replaces older content, and then the older content disappears. The local nature of the news means that users consume 90% of the content within the AWS Region where it is uploaded. Which solution will optimize the user experience by providing the LOWEST latency for content uploads?

Correct Answer: B. Upload and store content in Amazon S3 Use S3 Transfer Acceleration for the uploads.

Explanation

To optimize the user experience by providing the lowest latency for content uploads in a mobile app where users consume 90% of the content within the AWS Region where it is uploaded, the recommended solutionis:B. Upload and store content in Amazon S3. Use S3 Transfer Acceleration for the uploads. Option B provides a solution that optimizes the user experience with the lowest latency for content uploads:- Upload and store content in Amazon S3: Amazon S3 is a highly scalable and durable object storage service. It is well-suited for storing photos and videos in this scenario.- Use S3 Transfer Acceleration for the uploads: S3 Transfer Acceleration is a feature of Amazon S3 that utilizes Amazon CloudFront's globally distributed edge locations to accelerate uploads to Amazon S3. It optimizes the upload path by using the nearest CloudFront edge location, reducing the latency and improving the upload speed.Option A suggests using Amazon CloudFront for the uploads. While CloudFront can improve the performance for content delivery to end users, it does not directly optimize the upload latency for content being uploaded to S3.Option C suggests uploading content to Amazon EC2 instances in the region closest to the user and then copying the data to Amazon S3. This approach adds unnecessary complexity and introduces additional steps, which can increase latency and operational overhead.Option D suggests uploading and storing content in Amazon S3 in the region closest to the user and using multiple distributions of Amazon CloudFront. While CloudFront can improve content delivery, it does not directly address optimizing the upload latency for content uploads.Therefore, the best solution to optimize the user experience with the lowest latency for content uploads isB: Upload and store content in Amazon S3 and use S3 Transfer Acceleration for the uploads. This solution leverages the global presence of CloudFront edge locations to accelerate the upload process and provide a faster and smoother user experience.
