Solutions Architect Professional (Page 113)

A company is running a large containerized workload in the AWS Cloud.The workload consists of approximately 100 different services.The company uses Amazon Elastic Container Service (Amazon ECS) to orchestrate the workload.Recently the company’s development team started using AWS Fargate instead of Amazon EC2 instances in the ECS cluster.In the past, the workload has come close to running the maximum number of EC2 instances that are available in the account.The company is worried that the workload could reach the maximum number of ECS tasks that are allowed.A solutions architect must implement a solution that will notify the development team when Fargate reaches 80% of the maximum number of tasks.What should the solutions architect do to meet this requirement?Read More →

A large company is migrating its on-premises applications to the AWS Cloud.All the company’s AWS accounts belong to an organization in AWS Organizations.Each application is deployed into its own VPC in separate AWS accounts.The company decides to start the migration process by migrating the front-end web services while keeping the databases on premises.The databases are configured with local domain names that are specific to the on-premises environment.The local domain names must be resolvable from the migrated web services.Which solution will meet these requirements with the LEAST operational overhead?Read More →

A company’s interactive web application uses an Amazon CloudFront distribution to serve images from an Amazon S3 bucket.Occasionally, third-party tools ingest corrupted images into the S3 bucket.This image corruption causes a poor user experience in the application later.The company has successfully implemented and tested Python logic to detect corrupt images.A solutions architect must recommend a solution to integrate the detection logic with minimal latency between the ingestion and serving.Which solution will meet these requirements?Read More →

A company runs applications on Amazon EC2 instances.The company plans to begin using an Auto Scaling group for the instances.As part of this transition, a solutions architect must ensure that Amazon CloudWatch Logs automatically collects logs from all new instances.The new Auto Scaling group will use a launch template that includes the Amazon Linux 2 AMI and no key pair.Which solution meets these requirements?Read More →

A solutions architect is importing a VM from an on-premises environment by using the Amazon EC2 VM Import feature of AWS Import/Export.The solutions architect has created an AMI and has provisioned an Amazon EC2 instance that is based on that AMI.The EC2 instance runs inside a public subnet in a VPC and has a public IP address assigned.The EC2 instance does not appear as a managed instance in the AWS Systems Manager console.Which combination of steps should the solutions architect take to troubleshoot this issue? (Choose two.)Read More →

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? (Choose two.)Read More →

A company needs to implement a patching process for its servers.The on-premises servers and Amazon EC2 instances use a variety of tools to perform patching.Management requires a single report showing the patch status of all the servers and instances.Which set of actions should a solutions architect take to meet these requirements?Read More →
