• Question 883:

  A solutions architect is designing a multi-tier application for a company. The application's users upload images from a mobile device. The application generates a thumbnail of each image and returns a message to the user to confirm that the image was uploaded successfully. The thumbnail generation can take up to 60 seconds, but the company wants to provide a faster response time to its users to notify them that the original image was received. The solutions architect must design the application to asynchronously dispatch requests to the different application tiers.

  What should the solutions architect do to meet these requirements?

  A. Write a custom AWS Lambda function to generate the thumbnail and alert the user. Use the image upload process as an event source to invoke the Lambda function.
  B. Create an AWS Step Functions workflow. Configure Step Functions to handle the orchestration between the application tiers and alert the user when thumbnail generation is complete.
  C. Create an Amazon Simple Queue Service (Amazon SQS) message queue. As images are uploaded, place a message on the SQS queue for thumbnail generation. Alert the user through an application message that the image was received.
  D. Create Amazon Simple Notification Service (Amazon SNS) notification topics and subscriptions. Use one subscription with the application to generate the thumbnail after the image upload is complete. Use a second subscription to message the user's mobile app by way of a push notification after thumbnail generation is complete.
  C. Create an Amazon Simple Queue Service (Amazon SQS) message queue. As images are uploaded, place a message on the SQS queue for thumbnail generation. Alert the user through an application message that the image was received.

• Question 888:

  A company is developing a SaaS solution for customers. The solution runs on Amazon EC2 instances that have Amazon Elastic Block Store (Amazon EBS) volumes attached.

  Within the SaaS application, customers can request how much storage they need. The application needs to allocate the amount of block storage each customer requests.

  A solutions architect must design an operationally efficient solution that meets the storage scaling requirement.

  Which solution will meet these requirements MOST cost-effectively?

  A. Migrate the data from the EBS volumes to an Amazon S3 bucket. Use the Amazon S3 Standard storage class.
  B. Migrate the data from the EBS volumes to an Amazon Elastic File System (Amazon EFS) file system. Use the EFS Standard storage class. Invoke an AWS Lambda function to increase the EFS volume capacity based on user input.
  C. Migrate the data from the EBS volumes to an Amazon FSx for Windows File Server file system. Invoke an AWS Lambda function to increase the capacity of the file system based on user input.
  D. Invoke an AWS Lambda function to increase the size of EBS volumes based on user input by using EBS Elastic Volumes.
  D. Invoke an AWS Lambda function to increase the size of EBS volumes based on user input by using EBS Elastic Volumes.

  Explanation

  EBS Elastic Volumes allow you to dynamically increase storage size, adjust performance, and change volume types without downtime, supporting operational efficiency and scalability for SaaS applications that need to allocate varying storage amounts to customers. Migrating from EBS to S3 (Option A) is not suitable since S3 is object storage, not block storage, and does not support block-level I/O required by many applications. EFS (Option B) and FSx (Option C) are shared file systems, which might add unnecessary complexity and cost, especially if the application depends on block storage semantics.

  Using Lambda to automate Elastic Volumes resizing provides cost efficiency by allocating resources on demand and reduces operational overhead, aligning with AWS operational excellence and cost optimization best practices.
