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 →

A Solutions Architect is designing a highly available and reliable solution for a cluster of Amazon EC2 instances.The Solutions Architect must ensure that any EC2 instance within the cluster recovers automatically after a system failure.The solution must ensure that the recovered instance maintains the same IP address.How can these requirements be met?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 company is migrating an application to AWS.It wants to use fully managed services as much as possible during the migration.The company needs to store large, important documents within the application with the following requirements:✑ The data must be highly durable and available.✑ The data must always be encrypted at rest and in transit.✑ The encryption key must be managed by the company and rotated periodically.Which of the following solutions should the Solutions Architect recommend?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 company has a legacy application running on servers on premises.To increase the application’s reliability, the company wants to gain actionable insights using application logs.A Solutions Architect has been given following requirements for the solution:✑ Aggregate logs using AWS.✑ Automate log analysis for errors.✑ Notify the Operations team when errors go beyond a specified threshold.What solution meets the requirements?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 →

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 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 →
