A company needs to implement disaster recovery for a critical application that runs in a single AWS Region.The application’s users interact with a web frontend that is hosted on Amazon EC2 instances behind an Application Load Balancer (ALB).The application writes to an Amazon RDS for MySQL DB instance.The application also outputs processed documents that are stored in an Amazon S3 bucket.The company’s finance team directly queries the database to run reports.During busy periods, these queries consume resources and negatively affect application performance.A solutions architect must design a solution that will provide resiliency during a disaster.The solution must minimize data loss and must resolve the performance problems that result from the finance team’s queries.Which solution will meet these requirements?Read More →

A company has a photo sharing social networking application.To provide a consistent experience for users, the company performs some image processing on the photos uploaded by users before publishing on the application.The image processing is implemented using a set of Python libraries.The current architecture is as follows:✑ The image processing Python code runs in a single Amazon EC2 instance and stores the processed images in an Amazon S3 bucket named ImageBucket.✑ The front-end application, hosted in another bucket, loads the images from ImageBucket to display to users.With plans for global expansion, the company wants to implement changes in its existing architecture to be able to scale for increased demand on the application and reduce management complexity as the application scales.Which combination of changes should a solutions architect make? (Choose two.)Read More →

A company’s web application has reliability issues.The application serves customers globally.The application runs on a single Amazon EC2 instance and performs read-intensive operations on an Amazon RDS for MySQL database.During high load, the application becomes unresponsive and requires a manual restart of the EC2 instance.A solutions architect must improve the application’s reliability.Which solution will meet this requirement with the LEAST development effort?Read More →

A company’s factory and automation applications are running in a single VPC.More than 20 applications run on a combination of Amazon EC2, Amazon ElasticContainer Service (Amazon ECS), and Amazon RDS.The company has software engineers spread across three teams.One of the three teams owns each application, and each time is responsible for the cost and performance of all of its applications.Team resources have tags that represent their application and team.The teams use IAM access for daily activities.The company needs to determine which costs on the monthly AWS bill are attributable to each application or team.The company also must be able to create reports to compare costs from the last 12 months and to help forecast costs for the next 12 months.A solutions architect must recommend an AWS Billing andCost Management solution that provides these cost reports.Which combination of actions will meet these requirements?

A company uses a Grafana data visualization solution that runs on a single Amazon EC2 instance to monitor the health of the company’s AWS workloads.The company has invested time and effort to create dashboards that the company wants to preserve.The dashboards need to be highly available and cannot be down for longer than 10 minutes.The company needs to minimize ongoing maintenance.Which solution will meet these requirements with the LEAST operational overhead?Read More →

A company has set up a multi-account AWS environment by using AWS Control Tower.Each AWS account that AWS Control Tower creates has its own VPC.The company is developing an application that will integrate with many microservices.The company has designated a specific account to host the application.The company will deploy the microservices on Amazon EC2 instances and will implement the microservices across multiple AWS accounts.The microservices require a high degree of interconnectivity.The company needs a solution that will give the application the ability to communicate privately with the microservices.The solution also must minimize cost and operational overhead.Which solution will meet these requirements?Read More →

A company uses a load balancer to distribute traffic to Amazon EC2 instances in a single Availability Zone.The company is concerned about security and wants a solutions architect to re-architect the solution to meet the following requirements:• Inbound requests must be filtered for common vulnerability attacks.• Rejected requests must be sent to a third-party auditing application.• All resources should be highly available.Which solution meets these requirements?Read More →

A company uses multiple AWS accounts in a single AWS Region.A solutions architect is designing a solution to consolidate logs generated by Elastic LoadBalancers (ELBs) in the AppDev, AppTest, and AppProd accounts.The logs should be stored in an existing Amazon S3 bucket named s3-elb-logs in the centralAWS account.The central account is used for log consolidation only and does not have ELBs deployed.ELB logs must be encrypted at rest.Which combination of steps should the solutions architect take to build the solution?
