Solutions Architect Professional (Page 112)

A company needs to aggregate Amazon CloudWatch logs from its AWS accounts into one central logging account.The collected logs must remain in the AWS Region of creation.The central logging account will then process the logs, normalize the logs into standard output format, and stream the output logs to a security tool for more processing.A solutions architect must design a solution that can handle a large volume of logging data that needs to be ingested.Less logging will occur outside normal business hours than during normal business hours.The logging solution must scale with the anticipated load.The solutions architect has decided to use an AWS Control Tower design to handle the multi-account logging process.Which combination of steps should the solutions architect take to meet the requirements?

A company is deploying a distributed in-memory database on a fleet of Amazon EC2 instances.The fleet consists of a primary node and eight worker nodes.The primary node is responsible for monitoring cluster health, accepting user requests, distributing user requests to worker nodes, and sending an aggregate response back to a client.Worker nodes communicate with each other to replicate data partitions.The company requires the lowest possible networking latency to achieve maximum performance.Which solution will meet these requirements?Read More →

A company hosts a data-processing application on Amazon EC2 instances.The application polls an Amazon Elastic File System (Amazon EFS) file system for newly uploaded files.When a new file is detected, the application extracts data from the file and runs logic to select a Docker container image to process the file.The application starts the appropriate container image and passes the file location as a parameter.The data processing that the container performs can take up to 2 hours.When the processing is complete, the code that runs inside the container writes the file back to Amazon EFS and exits.The company needs to refactor the application to eliminate the EC2 instances that are running the containers.Which solution will meet these requirements?Read More →

A company built an ecommerce website on AWS using a three-tier web architecture.The application is Java-based and composed of an Amazon CloudFront distribution, an Apache web server layer of Amazon EC2 instances in an Auto Scaling group, and a backend Amazon Aurora MySQL database.Last month, during a promotional sales event, users reported errors and timeouts while adding items to their shopping carts.The operations team recovered the logs created by the web servers and reviewed Aurora DB cluster performance metrics.Some of the web servers were terminated before logs could be collected and the Aurora metrics were not sufficient for query performance analysis.Which combination of steps must the solutions architect take to improve application performance visibility during peak traffic events?

An online survey company runs its application in the AWS Cloud.The application is distributed and consists of microservices that run in an automatically scaled Amazon Elastic Container Service (Amazon ECS) cluster.The ECS cluster is a target for an Application Load Balancer (ALB).The ALB is a custom origin for an Amazon CloudFront distribution.The company has a survey that contains sensitive data.The sensitive data must be encrypted when it moves through the application.The application’s data-handling microservice is the only microservice that should be able to decrypt the dataWhich solution will meet these requirements?Read More →

A company runs a serverless application in a single AWS Region.The application accesses external URLs and extracts metadata from those sites.The company uses an Amazon Simple Notification Service (Amazon SNS) topic to publish URLs to an Amazon Simple Queue Service (Amazon SQS) queue.An AWS Lambda function uses the queue as an event source and processes the URLs from the queue.Results are saved to an Amazon S3 bucket.The company wants to process each URL in other Regions to compare possible differences in site localization.URLs must be published from the existing Region.Results must be written to the existing S3 bucket in the current Region.Which combination of changes will produce multi-Region deployment that meets these requirements? (Choose two.)Read More →

A company hosts a software as a service (SaaS) solution on AWS.The solution has an Amazon API Gateway API that serves an HTTPS endpoint.The API uses AWS Lambda functions for compute.The Lambda functions store data in an Amazon Aurora Serverless v1 database.The company used the AWS Serverless Application Model (AWS SAM) to deploy the solution.The solution extends across multiple Availability Zones and has no disaster recovery (DR) plan.A solutions architect must design a DR strategy that can recover the solution in another AWS Region.The solution has an RTO of 5 minutes and an RPO of 1 minute.What should the solutions architect do to meet these requirements?Read More →

A company is building an image service on the web that will allow users to upload and search random photos.At peak usage, up to 10,000 users worldwide will upload their images.The service will then overlay text on the uploaded images, which will then be published on the company website.Which design should a solutions architect implement?Read More →

An events company runs a ticketing platform on AWS.The company’s customers configure and schedule their events on the platform.The events result in large increases of traffic to the platform.The company knows the date and time of each customer’s events.The company runs the platform on an Amazon Elastic Container Service (Amazon ECS) cluster.The ECS cluster consists of Amazon EC2 On-Demand Instances that are in an Auto Scaling group.The Auto Scaling group uses a predictive scaling policy.The ECS cluster makes frequent requests to an Amazon S3 bucket to download ticket assets.The ECS cluster and the S3 bucket are in the same AWS Region and the same AWS account.Traffic between the ECS cluster and the S3 bucket flows across a NAT gateway.The company needs to optimize the cost of the platform without decreasing the platform’s availability.Which combination of steps will meet these requirements?

A company has a policy that all Amazon EC2 instances that are running a database must exist within the same subnets in a shared VPC.Administrators must follow security compliance requirements and are not allowed to directly log in to the shared account.All company accounts are members of the same organization in AWS Organizations.The number of accounts will rapidly increase as the company grows.A solutions architect uses AWS Resource Access Manager to create a resource share in the shared account.What is the MOST operationally efficient configuration to meet these requirements?Read More →
