A software company is using three AWS accounts for each of its 10 development teams.The company has developed an AWS CloudFormation standard VPC template that includes three NAT gateways.The template is added to each account for each team.The company is concerned that network costs will increase each time a new development team is added.A solutions architect must maintain the reliability of the company’s solutions and minimize operational complexity.What should the solutions architect do to reduce the network costs while meeting these requirements?Read More →

Accompany is building an application to collect and transmit sensor data from a factory.The application will use AWS IoT Core to send data from hundreds of devices to an Amazon S3 data lake.The company must enrich the data before loading the data into Amazon S3.The application will transmit the sensor data every 5 seconds.New sensor data must be available in Amazon S3 less than 30 minutes after the application collects the data.No other applications are processing the sensor data from AWS IoT Core.Which solution will meet these requirements MOST cost-effectively?Read More →

A company uses a load balancer to distribute traffic to Amazon EC2 instances in a single Availability Zone.The company is concerned about security and wants a solutions architect to re-architect the solution to meet the following requirements:✑ Inbound requests must be filtered for common vulnerability attacks.✑ Rejected requests must be sent to a third-party auditing application.✑ All resources should be highly available.Which solution meets these requirements?Read More →

A company is running a web-crawling process on a list of target URLs to obtain training documents for machine learning training algorithms.A fleet of Amazon EC2 t2.micro instances pulls the target URLs from an Amazon Simple Queue Service (Amazon SQS) queue.The instances then write the result of the crawling algorithm as a .csv file to an Amazon Elastic File System (Amazon EFS) volume.The EFS volume is mounted on all instances of the fleet.A separate system adds the URLs to the SQS queue at infrequent rates.The instances crawl each URL in 10 seconds or less.Metrics indicate that some instances are idle when no URLs are in the SQS queue.A solutions architect needs to redesign the architecture to optimize costs.Which combination of steps will meet these requirements MOST cost-effectively?
