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 →

An auction website enables users to bid on collectible items.The auction rules require that each bid is processed only once and in the order it was received.The current implementation is based on a fleet of Amazon EC2 web servers that write bid records into Amazon Kinesis Data Streams.A single t2.large instance has a cron job that runs the bid processor, which reads incoming bids from Kinesis Data Streams and processes each bid.The auction site is growing in popularity, but users are complaining that some bids are not registering.Troubleshooting indicates that the bid processor is too slow during peak demand hours, sometimes crashes while processing, and occasionally loses track of which records is being processed.What changes should make the bid processing more reliable?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 →
