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?

A company is running a containerized application in the AWS Cloud.The application is running by using Amazon Elastic Container Service (Amazon ECS) on a set of Amazon EC2 instances.The EC2 instances run in an Auto Scaling group.The company uses Amazon Elastic Container Registry (Amazon ECR) to store its container images.When a new image version is uploaded, the new image version receives a unique tag.The company needs a solution that inspects new image versions for common vulnerabilities and exposures.The solution must automatically delete new image tags that have Critical or High severity findings.The solution also must notify the development team when such a deletion occurs.Which solution meets these requirements?Read More →

An international delivery company hosts a delivery management system on AWS.Drivers use the system to upload confirmation of delivery.Confirmation includes the recipient’s signature or a photo of the package with the recipient.The driver’s handheld device uploads signatures and photos through FTP to a single Amazon EC2 instance.Each handheld device saves a file in a directory based on the signed-in user, and the file name matches the delivery number.The EC2 instance then adds metadata to the file after querying a central database to pull delivery information.The file is then placed in Amazon S3 for archiving.As the company expands, drivers report that the system is rejecting connections.The FTP server is having problems because of dropped connections and memory issues in response to these problems, a system engineer schedules a cron task to reboot the EC2 instance every 30 minutes.The billing team reports that files are not always in the archive and that the central system is not always updated.A solutions architect needs to design a solution that maximizes scalability to ensure that the archive always receives the files and that systems are always updated.The handheld devices cannot be modified, so the company cannot deploy a new application.Which solution will meet these requirements?Read More →

A company wants to migrate its website from an on-premises data center onto AWS.At the same time, it wants to migrate the website to a containerized microservice-based architecture to improve the availability and cost efficiency.The company’s security policy states that privileges and network permissions must be configured according to best practice, using least privilege.A solutions architect must create a containerized architecture that meets the security requirements and has deployed the application to an Amazon ECS cluster.What steps are required after the deployment to meet the requirements? (Choose two.)Read More →

A company provides a software as a service (SaaS) application that runs in the AWS Cloud.The application runs on Amazon EC2 instances behind a Network Load Balancer (NLB).The instances are in an Auto Scaling group and are distributed across three Availability Zones in a single AWS Region.The company is deploying the application into additional Regions.The company must provide static IP addresses for the application to customers so that the customers can add the IP addresses to allow lists.The solution must automatically route customers to the Region that is geographically closest to them.Which solution will meet these requirements?Read More →

A company hosts a web application on AWS in the us-east-1 Region.The application servers are distributed across three Availability Zones behind an Application Load Balancer.The database is hosted in a MySQL database on an Amazon EC2 instance.A solutions architect needs to design a cross-Region data recovery solution using AWS services with an RTO of less than 5 minutes and an RPO of less than 1 minute.The solutions architect is deploying application servers in us-west-2, and has configured Amazon Route 53 health checks and DNS failover to us-west-2.Which additional step should the solutions architect take?Read More →

A company has mounted sensors to collect information about environmental parameters such as humidity and light throughout all the company’s factories.The company needs to stream and analyze the data in the AWS Cloud in real time.If any of the parameters fall out of acceptable ranges, the factory operations team must receive a notification immediately.Which solution will meet these requirements?Read More →

A retail company wants to improve its application architecture.The company’s applications register new orders, handle returns of merchandise, and provide analytics.The applications store retail data in a MySQL database and an Oracle OLAP analytics database.All the applications and databases are hosted on Amazon EC2 instances.Each application consists of several components that handle different parts of the order process.These components use incoming data from different sources.A separate ETL job runs every week and copies data from each application to the analytics database.A solutions architect must redesign the architecture into an event-driven solution that uses serverless services.The solution must provide updated analytics in near real time.Which solution will meet these requirements?Read More →

An online magazine will launch its latest edition this month.This edition will be the first to be distributed globally.The magazine’s dynamic website currently uses an Application Load Balancer in front of the web tier, a fleet of Amazon EC2 instances for web and application servers, and Amazon Aurora MySQL.Portions of the website include static content and almost all traffic is read-only.The magazine is expecting a significant spike in internet traffic when the new edition is launched.Optimal performance is a top priority for the week following the launch.Which combination of steps should a solutions architect take to reduce system response times for a global audience? (Choose two.)Read More →

A company has millions of objects in an Amazon S3 bucket.The objects are in the S3 Standard storage class.All the S3 objects are accessed frequently.The number of users and applications that access the objects is increasing rapidly.The objects are encrypted with server-side encryption with AWS KMS keys (SSE-KMS).A solutions architect reviews the company’s monthly AWS invoice and notices that AWS KMS costs are increasing because of the high number of requests from Amazon S3.The solutions architect needs to optimize costs with minimal changes to the application.Which solution will meet these requirements with the LEAST operational overhead?Read More →
