AWS Certified Solutions Architect - Professional SAP-C02 — Topic 1 Question 397

Question

A company needs to store and process image data that will be uploaded from mobile devices using a custom mobile app. Usage peaks between 8 AM and 5 PM on weekdays, with thousands of uploads per minute. The app is rarely used at any other time. A user is notified when image processing is complete. Which combination of actions should a solutions architect take to ensure image processing can scale to handle the load? (Choose three.)

Accepted Answer

Correct answer: B, C, E. The correct answer is B, C, E. Option B: Upload files from the mobile software directly to Amazon S3. Use S3 event notifications to create a message in an Amazon Simple Queue Service (Amazon SQS) standard queue. Option C: Invoke an AWS Lambda function to perform image processing when a message is available in the queue. Option E: Send a push notification to the mobile app by using Amazon Simple Notification Service (Amazon SNS) when processing is complete. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon S3 provides durable, scalable object storage that is fully managed. Amazon SQS is a fully managed message queue that decouples components and absorbs traffic spikes.
