A company is running a critical stateful web application on two Linux Amazon EC2 instances behind an Application Load Balancer (ALB) with an Amazon RDS for MySQL database.The company hosts the DNS records for the application in Amazon Route 53.A solutions architect must recommend a solution to improve the resiliency of the application.The solution must meet the following objectives:• Application tier: RPO of 2 minutes.RTO of 30 minutes• Database tier: RPO of 5 minutes.RTO of 30 minutesThe company does not want to make significant changes to the existing application architecture.The company must ensure optimal latency after a failover.Which solution will meet these requirements?Read More →

A solutions architect needs to deploy an application on a fleet of Amazon EC2 Instances.The EC2 instances run in private subnets in an Auto Scaling group.The application is expected to generate logs at a rate of 100 MB each second on each of the EC2 instances.The logs must be stored in an Amazon S3 bucket so that an Amazon EMR cluster can consume them for further processing.The logs must be quickly accessible for the first 90 days and should be retrievable within 48 hours thereafter.What is the MOST cost-effective solution that meets these requirements?Read More →

A company wants to use Amazon WorkSpaces in combination with thin client devices to replace aging desktops.Employees use the desktops to access applications that work with Clinical trial data.Corporate security policy states that access to the applications must be restricted to only company branch office locations.The company is considering adding an additional branch office in the next 6 months.Which solution meets these requirements with the MOST operational efficiency?Read More →

A solutions architect is building a web application that uses an Amazon RDS for PostgreSQL DB instance.The DB instance is expected to receive many more reads than writes.The solutions architect needs to ensure that the large amount of read traffic can be accommodated and that the DB instance is highly available.Which steps should the solutions architect take to meet these requirements?

A company is planning to migrate an Amazon RDS for Oracle database to an RDS for PostgreSQL DB instance in another AWS account.A solutions architect needs to design a migration strategy that will require no downtime and that will minimize the amount of time necessary to complete the migration.The migration strategy must replicate all existing data and any new data that is created during the migration.The target database must be identical to the source database at completion of the migration process.All applications currently use an Amazon Route 53 CNAME record as their endpoint for communication with the RDS for Oracle DB instance.The RDS for Oracle DB instance is in a private subnet.Which combination of steps should the solutions architect take to meet these requirements? (Choose three.)Read More →

A company uses AWS Organizations to manage one parent account and nine member accounts.The number of member accounts is expected to grow as the business grows.A security engineer has requested consolidation of AWS CloudTrail logs into the parent account for compliance purposes.Existing logs currently stored in Amazon S3 buckets in each individual member account should not be lost.Future member accounts should comply with the logging strategy.Which operationally efficient solution meets these requirements?Read More →

A solutions architect is reviewing an application’s resilience before launch.The application runs on an Amazon EC2 instance that is deployed in a private subnet of a VPC.The EC2 instance is provisioned by an Auto Scaling group that has a minimum capacity of 1 and a maximum capacity of 1.The application stores data on an Amazon RDS for MySQL DB instance.The VPC has subnets configured in three Availability Zones and is configured with a single NAT gateway.The solutions architect needs to recommend a solution to ensure that the application will operate across multiple Availability Zones.Which solution will meet this requirement?Read More →

A company has a primary Amazon S3 bucket that receives thousands of objects every day.The company needs to replicate these objects into several other S3 buckets from various AWS accounts.A solutions architect is designing a new AWS Lambda function that is triggered when an object is created in the main bucket and replicates the object into the target buckets.The objects do not need to be replicated in real time.There is concern that this function may impact other criticalLambda functions due to Lambda’s regional concurrency limit.How can the solutions architect ensure this new Lambda function will not impact other critical Lambda functions?Read More →
