AWS Certified Solutions Architect - Professional Questions and Answers

Question 1

A company provides auction services for artwork and has users across North America and Europe. The company hosts its application in Amazon EC2 instances in the us-east-1 Region. Artists upload photos of their work as large-size, high-resolution image files from their mobile phones to a centralized Amazon S3 bucket created in the us-east-l Region. The users in Europe are reporting slow performance for their Image uploads.

How can a solutions architect improve the performance of the image upload process?

Options:

Redeploy the application to use S3 multipart uploads.

Create an Amazon CloudFront distribution and point to the application as a custom origin

Configure the buckets to use S3 Transfer Acceleration.

Create an Auto Scaling group for the EC2 instances and create a scaling policy.

Question 2

A company has a Windows-based desktop application that is packaged and deployed to the users ' Windows machines. The company recently acquired another company that has employees who primarily use machines with a Linux operating system. The acquiring company has decided to migrate and rehost the Windows-based desktop application lo AWS.

All employees must be authenticated before they use the application. The acquiring company uses Active Directory on premises but wants a simplified way to manage access to the application on AWS (or all the employees.

Which solution will rehost the application on AWS with the LEAST development effort?

Options:

Set up and provision an Amazon Workspaces virtual desktop for every employee. Implement authentication by using Amazon Cognito identity pools. Instruct employees to run the application from their provisioned Workspaces virtual desktops.

Create an Auto Scarlet group of Windows-based Ama7on EC2 instances. Join each EC2 instance to the company ' s Active Directory domain. Implement authentication by using the Active Directory That is running on premises. Instruct employees to run the application by using a Windows remote desktop.

Use an Amazon AppStream 2.0 image builder to create an image that includes the application and the required configurations. Provision an AppStream 2.0 On-Demand fleet with dynamic Fleet Auto Scaling process for running the image. Implement authentication by using AppStream 2.0 user pools. Instruct the employees to access the application by starling browse ' -based AppStream 2.0 streaming sessions.

Refactor and containerize the application to run as a web-based application. Run the application in Amazon Elastic Container Service (Amazon ECS) on AWS Fargate with step scaling policies Implement authentication by using Amazon Cognito user pools. Instruct the employees to run the application from their browsers.

Question 3

A company is migrating a document processing workload to AWS. Client applications upload documents to an Amazon S3 bucket for processing. A document processing engine runs on an Amazon EC2 Linux instance and requires Portable Operating System Interface (POSIX)-compliant file system access to read, generate, and modify files during processing. The processed documents must be automatically available in the S3 bucket for client applications to download.

The company cannot directly modify the document processing engine to use the S3 API. The company needs a solution that provides the EC2 instance with file system access. The solution must maintain automatic synchronization with the S3 bucket for both input and output files.

Which solution will meet these requirements?

Options:

Configure AWS DataSync to connect to the EC2 instance without an agent. Configure a DataSync task in enhanced mode to synchronize the processed documents to and from Amazon S3.

Configure an Amazon FSx for Lustre file system with import and export policies that are linked to the S3 bucket. Install the Lustre client on the EC2 instance and mount the file system.

Create an Amazon EFS file system. Set the data repository associations to the S3 bucket. Install the EFS client and mount the file system. Create an automatic import and export policy for new and changed objects.

Set up an Amazon S3 File Gateway. Initiate a RefreshCache API call to update the S3 File Gateway when changes occur in Amazon S3.

Answer:

Explanation:

B is correct because Amazon FSx for Lustre provides a high-performance, POSIX-compliant file system that can be directly linked with Amazon S3 using data repository integration. This allows the EC2-based processing engine (which requires POSIX file operations) to read/write files through a mounted Lustre file system while automatically importing objects from S3 and exporting results back to S3 using Lustre’s S3 integration policies. This satisfies all requirements: POSIX file access, no need to change the application to use the S3 API, and automated synchronization for both inputs and outputs.

Why the other options are incorrect:

A: DataSync is designed for scheduled or task-based data transfers. It does not provide a mounted POSIX file system interface for the application to read/write “in place,” and the “without an agent” requirement is not a fit for an EC2-hosted POSIX workflow that needs continuous file semantics.

C: Amazon EFS is POSIX and mountable, but “data repository associations to S3” is not an EFS capability in the way described. EFS does not provide native bidirectional automatic sync with S3 using import/export policies like FSx for Lustre’s S3 integration.

D: S3 File Gateway provides a file interface backed by S3, but keeping cache coherent with explicit RefreshCache calls is operationally complex and not truly “automatic synchronization” in the sense required. It also introduces caching behaviors that can complicate immediate availability expectations.
