An application is using an Amazon RDS for MySQL Multi-AZ DB instance in the us-east-1 Region.After a failover test, the application lost the connections to the database and could not re-establish the connections.After a restart of the application, the application re-established the connections.A solutions architect must implement a solution so that the application can re-establish connections to the database without requiring a restart.Which solution will meet these requirements?Read More →

A video streaming company recently launched a mobile app for video sharing.The app uploads various files to an Amazon S3 bucket in the us-east-1 Region.The files range in size from 1 GB to 10 GB.Users who access the app from Australia have experienced uploads that take long periods of time.Sometimes the files fail to completely upload for these users.A solutions architect must improve the app’s performance for these uploads.Which solutions will meet these requirements?

A company has AWS accounts that are in an organization in AWS Organizations.The company wants to track Amazon EC2 usage as a metric.The company’s architecture team must receive a daily alert if the EC2 usage is more than 10% higher the average EC2 usage from the last 30 days.Which solution will meet these requirements?Read More →

A company runs a highly available data collection application on Amazon EC2 in the eu-north-1 Region.The application collects data from end-user devices and writes records to an Amazon Kinesis data stream and a set of AWS Lambda functions that process the records.The company persists the output of the record processing to an Amazon S3 bucket in eu-north-1.The company uses the data in the S3 bucket as a data source for Amazon Athena.The company wants to increase its global presence.A solutions architect must launch the data collection capabilities in the sa-east-1 and ap-northeast-1 Regions.The solutions architect deploys the application, the Kinesis data stream, and the Lambda functions in the two new Regions.The solutions architect keeps the S3 bucket in eu-north-1 to meet a requirement to centralize the data analysis.During testing of the new setup, the solutions architect notices a significant lag on the arrival of data from the new Regions to the S3 bucket.Which solution will improve this lag time the MOST?Read More →

A company wants to migrate its website to AWS.The website uses microservices and runs on containers that are deployed in an on-premises, self-managed Kubernetes cluster.All the manifests that define the deployments for the containers in the Kubernetes deployment are in source control.All data for the website is stored in a PostgreSQL database.An open source container image repository runs alongside the on-premises environment.A solutions architect needs to determine the architecture that the company will use for the website on AWS.Which solution will meet these requirements with the LEAST effort to migrate?Read More →

A company has deployed an application on AWS Elastic Beanstalk.The application uses Amazon Aurora for the database layer.An Amazon CloudFront distribution serves web requests and includes the Elastic Beanstalk domain name as the origin server.The distribution is configured with an alternate domain name that visitors use when they access the application.Each week, the company takes the application out of service for routine maintenance.During the time that the application is unavailable, the company wants visitors to receive an informational message instead of a CloudFront error message.A solutions architect creates an Amazon S3 bucket as the first step in the process.Which combination of steps should the solutions architect take next to meet the requirements? (Choose three.)Read More →

A life sciences company is using a combination of open source tools to manage data analysis workflows and Docker containers running on servers in its on-premises data center to process genomics data.Sequencing data is generated and stored on a local storage area network (SAN), and then the data is processed.The research and development teams are running into capacity issues and have decided to re-architect their genomics analysis platform on AWS to scale based on workload demands and reduce the turnaround time from weeks to days.The company has a high-speed AWS Direct Connect connection.Sequencers will generate around 200 GB of data for each genome, and individual jobs can take several hours to process the data with ideal compute capacity.The end result will be stored in Amazon S3.The company is expecting 10-15 job requests each day.Which solution meets these requirements?Read More →

A solutions architect must analyze a company’s Amazon EC2 instances and Amazon Elastic Block Store (Amazon EBS) volumes to determine whether the company is using resources efficiently.The company is running several large, high-memory EC2 instances to host database clusters that are deployed in active/passive configurations.The utilization of these EC2 instances varies by the applications that use the databases, and the company has not identified a pattern.The solutions architect must analyze the environment and take action based on the findings.Which solution meets these requirements MOST cost-effectively?Read More →

An external audit of a company’s serverless application reveals IAM policies that grant too many permissions.These policies are attached to the company’s AWS Lambda execution roles.Hundreds of the company’s Lambda functions have broad access permissions such as full access to Amazon S3 buckets and Amazon DynamoDB tables.The company wants each function to have only the minimum permissions that the function needs to complete its task.A solutions architect must determine which permissions each Lambda function needs.What should the solutions architect do to meet this requirement with the LEAST amount of effort?Read More →

A software company hosts an application on AWS with resources in multiple AWS accounts and Regions.The application runs on a group of Amazon EC2 instances in an application VPC located in the us-east-1 Region with an IPv4 CIDR block of 10.10.0.0/16.In a different AWS account, a shared services VPC is located in the us-east-2 Region with an IPv4 CIDR block of 10.10.10.0/24.When a cloud engineer uses AWS CloudFormation to attempt to peer the application VPC with the shared services VPC, an error message indicates a peering failure.Which factors could cause this error? (Choose two.)Read More →
