A company uses AWS Organizations.The company creates a central VPC in an AWS account that is designated for networking in a single AWS Region.The central VPC has an AWS Site-to-Site VPN connection to the company’s on-premises network.A solutions architect must create another AWS account that uses the same networking resources that the central VPC uses.Which solution meets these requirements MOST cost-effectively?Read More →

A company needs to migrate 60 on-premises legacy applications to AWS.The applications are based on the NET Framework and run on Windows.The company needs a solution that minimizes migration time and requires no application code changes.The company also does not want to manage the infrastructure.Which solution will meet these requirements?Read More →

A company is running an application in the AWS Cloud.The company has several third-party services that integrate with the application through a RESTful API.The API is a serverless implementation with an Amazon API Gateway regional API endpoint that integrates with several different AWS Lambda functions.The application’s data is nonrelational and is stored in an Amazon DynamoDB table.The application and the API are running in the eu-west-1 Region.The company needs the API to also be available in the us-east-1 Region.All data must be available in both Regions.A solutions architect already has deployed all the Lambda functions in us-east-1.Which additional steps should the solutions architect take to meet these requirements? (Choose two.)Read More →

A company has an application in the AWS Cloud.The application runs on a fleet of 20 Amazon EC2 instances.The EC2 instances are persistent and store data on multiple attached Amazon Elastic Block Store (Amazon EBS) volumes.The company must maintain backups in a separate AWS Region.The company must be able to recover the EC2 instances and their configuration within 1 business day, with loss of no more than 1 day’s worth of data.The company has limited staff and needs a backup solution that optimizes operational efficiency and cost.The company already has created an AWS CloudFormation template that can deploy the required network configuration in a secondary Region.Which solution will meet these requirements?Read More →

A solutions architect needs to improve an application that is hosted in the AWS Cloud.The application uses an Amazon Aurora MySQL DB instance that is experiencing overloaded connections.Most of the application’s operations insert records into the database.The application currently stores credentials in a text-based configuration file.The solutions architect needs to implement a solution so that the application can handle the current connection load.The solution must keep the credentials secure and must provide the ability to rotate the credentials automatically on a regular basis.Which solution will meet these requirements?Read More →

A company wants to optimize AWS data-transfer costs and compute costs across developer accounts within the company’s organization in AWS Organizations.Developers can configure VPCs and launch Amazon EC2 instances in a single AWS Region.The EC2 instances retrieve approximately 1 TB of data each day from Amazon S3.The developer activity leads to excessive monthly data-transfer charges and NAT gateway processing charges between EC2 instances and S3 buckets, along with high compute costs.The company wants to proactively enforce approved architectural patterns for any EC2 instance and VPC infrastructure that developers deploy within the AWS accounts.The company does not want this enforcement to negatively affect the speed at which the developers can perform their tasks.Which solution will meet these requirements MOST cost-effectively?Read More →

A company needs to move its write-intensive Amazon RDS for PostgreSQL database from the eu-west-1 Region to the eu-north-1 Region.As part of the migration, the company needs to change from Amazon RDS for PostgreSQL to Amazon Aurora PostgreSQL.The company is using a new AWS account to host a new Aurora PostgreSQL DB cluster.The RDS database is encrypted with an AWS managed AWS Key Management Service (AWS KMS) key.There must be no interruption to applications that use the RDS for PostgreSQL DB instance.Which solution will meet these requirements?Read More →

An ecommerce company runs an application on AWS.The application has an Amazon API Gateway API that invokes an AWS Lambda function.The data is stored in an Amazon RDS for PostgreSQL DB instance.During the company’s most recent flash sale, a sudden increase in API calls negatively affected the application’s performance.A solutions architect reviewed the Amazon CloudWatch metrics during that time and noticed a significant increase in Lambda invocations and database connections.The CPU utilization also was high on the DB instance.What should the solutions architect recommend to optimize the application’s performance?Read More →

A company has an Amazon S3 bucket that contains millions of unencrypted objects.To comply with a recent security audit, a solutions architect needs to ensure that all objects are encrypted and needs to compile a list of objects that contain sensitive data.Many applications access objects in the S3 bucket, and the development team has limited resources.Which solution will meet these requirements with the LEAST development effort?Read More →

A company recently completed a successful proof of concept of Amazon WorkSpaces.A solutions architect needs to make the solution highly available across two AWS Regions.Amazon WorkSpaces is deployed in a failover Region, and a hosted zone is deployed in Amazon Route 53.What should the solutions architect do to configure high availability for the solution?Read More →
