A company runs a serverless application in a single AWS Region.The application accesses external URLs and extracts metadata from those sites.The company uses an Amazon Simple Notification Service (Amazon SNS) topic to publish URLs to an Amazon Simple Queue Service (Amazon SQS) queue.An AWS Lambda function uses the queue as an event source and processes the URLs from the queue.Results are saved to an Amazon S3 bucket.The company wants to process each URL in other Regions to compare possible differences in site localization.URLs must be published from the existing Region.Results must be written to the existing S3 bucket in the current Region.Which combination of changes will produce multi-Region deployment that meets these requirements? (Choose two.)Read More →

A company has a legacy application that runs on multiple NET Framework components.The components share the same Microsoft SQL Server database and communicate with each other asynchronously by using Microsoft Message Queueing (MSMQ).The company is starting a migration to containerized .NET Core components and wants to refactor the application to run on AWS.The .NET Core components require complex orchestration.The company must have full control over networking and host configuration.The application’s database model is strongly relational.Which solution will meet these requirements?Read More →

A company runs a proprietary stateless ETL application on an Amazon EC2 Linux instances.The application is a Linux binary, and the source code cannot be modified.The application is single-threaded, uses 2 GB of RAM, and is highly CPU intensive.The application is scheduled to run every 4 hours and runs for up to 20 minutes.A solutions architect wants to revise the architecture for the solution.Which strategy should the solutions architect use?Read More →

A company runs many workloads on AWS and uses AWS Organizations to manage its accounts.The workloads are hosted on Amazon EC2.AWS Fargate.and AWS Lambda.Some of the workloads have unpredictable demand.Accounts record high usage in some months and low usage in other months.The company wants to optimize its compute costs over the next 3 years.A solutions architect obtains a 6-month average for each of the accounts across the organization to calculate usage.Which solution will provide the MOST cost savings for all the organization’s compute usage?Read More →

A company needs to migrate its website from an on-premises data center to AWS.The website consists of a load balancer, a content management system (CMS) that runs on a Linux operating system, and a MySQL database.The CMS requires persistent NFS-compatible storage for a file system.The new solution on AWS must be able to scale from 2 Amazon EC2 instances to 30 EC2 instances in response to unpredictable traffic increases.The new solution also must require no changes to the website and must prevent data loss.Which solution will meet these requirements?Read More →

A company runs an IoT application in the AWS Cloud.The company has millions of sensors that collect data from houses in the United States.The sensors use the MQTT protocol to connect and send data to a custom MQTT broker.The MQTT broker stores the data on a single Amazon EC2 instance.The sensors connect to the broker through the domain named iot.example.com.The company uses Amazon Route 53 as its DNS service.The company stores the data in Amazon DynamoDB.On several occasions, the amount of data has overloaded the MQTT broker and has resulted in lost sensor data.The company must improve the reliability of the solution.Which solution will meet these requirements?Read More →

A company is using GitHub Actions to run a CI/CD pipeline that accesses resources on AWS.The company has an IAM user that uses a secret key in the pipeline to authenticate to AWS.An existing IAM role with an attached policy grants the required permissions to deploy resources.The company’s security team implements a new requirement that pipelines can no longer use long-lived secret keys.A solutions architect must replace the secret key with a short-lived solution.Which solution will meet these requirements with the LEAST operational overhead?Read More →

A company manages hundreds of AWS accounts centrally in an organization in AWS Organizations.The company recently started to allow product teams to create and manage their own S3 access points in their accounts.The S3 access points can be accessed only within VPCs, not on the internet.What is the MOST operationally efficient way to enforce this requirement?Read More →

A company is currently in the design phase of an application that will need an RPO of less than 5 minutes and an RTO of less than 10 minutes.The solutions architecture team is forecasting that the database will store approximately 10 TB of data.As part of the design, they are looking for a database solution that will provide the company with the ability to fail over to a secondary Region.Which solution will meet these business requirements at the LOWEST cost?Read More →

A company owns a chain of travel agencies and is running an application in the AWS Cloud.Company employees use the application to search for information about travel destinations.Destination content is updated four times each year.Two fixed Amazon EC2 instances serve the application.The company uses an Amazon Route 53 public hosted zone with a multivalue record of travel.example.com that returns the Elastic IP addresses for the EC2 instances.The application uses Amazon DynamoDB as its primary data store.The company uses a self-hosted Redis instance as a caching solution.During content updates, the load on the EC2 instances and the caching solution increases drastically.This increased load has led to downtime on several occasions.A solutions architect must update the application so that the application is highly available and can handle the load that is generated by the content updates.Which solution will meet these requirements?Read More →
