A solutions architect is designing the cloud architecture for a new application that is being deployed on AWS.The application’s users will interactively download and upload files.Files that are more than 90 days old will be accessed less frequently than newer files, but all files need to be instantly available.The solutions architect must ensure that the application can scale to store petabytes of data with maximum durability.Which solution meets these requirements?Read More →

A solutions architect needs to design the architecture for an application that a vendor provides as a Docker container image.The container needs 50 GB of storage available for temporary files.The infrastructure must be serverless.Which solution meets these requirements with the LEAST operational overhead?Read More →

A company’s facility has badge readers at every entrance throughout the building.When badges are scanned, the readers send a message over HTTPS to indicate who attempted to access that particular entrance.A solutions architect must design a system to process these messages from the sensors.The solution must be highly available, and the results must be made available for the company’s security team to analyze.Which system architecture should the solutions architect recommend?Read More →

A company hosts its application in the AWS Cloud.The application runs on Amazon EC2 instances behind an Elastic Load Balancer in an Auto Scaling group and with an Amazon DynamoDB table.The company wants to ensure the application can be made available in another AWS Region with minimal downtime.What should a solutions architect do to meet these requirements with the LEAST amount of downtime?Read More →

A solutions architect needs to design a solution that retrieves data every 2 minutes from a third-party web service that is accessible through the internet.A Python script runs the data retrieval in less than 100 milliseconds for each retrieval.The response is a JSON object that contains sensor data that is less than 1 KB in size.The solutions architect needs to store the JSON object along with the timestamp.Which solution meets these requirements MOST cost-effectively?Read More →

A company wants to migrate its MySQL database from on premises to AWS.The company recently experienced a database outage that significantly impacted the business.To ensure this does not happen again, the company wants a reliable database solution on AWS that minimizes data loss and stores every transaction on at least two nodes.Which solution meets these requirements?Read More →

A company is using a fleet of Amazon EC2 instances to ingest data from on-premises data sources.The data is in JSON format and ingestion rates can be as high as 1 MB/s.When an EC2 instance is rebooted, the data in-flight is lost.The company’s data science team wants to query ingested data in near-real time.Which solution provides near-real-time data querying that is scalable with minimal data loss?Read More →

The financial application at a company stores monthly reports in an Amazon S3 bucket.The vice president of finance has mandated that all access to these reports be logged and that any modifications to the log files be detected.Which actions can a solutions architect take to meet these requirements?Read More →

An ecommerce website is deploying its web application as Amazon Elastic Container Service (Amazon ECS) container instances behind an Application LoadBalancer (ALB).During periods of high activity, the website slows down and availability is reduced.A solutions architect uses Amazon CloudWatch alarms to receive notifications whenever there is an availability issue so they can scale out resources.Company management wants a solution that automatically responds to such events.Which solution meets these requirements?Read More →

A company has an application workflow that uses an AWS Lambda function to download and decrypt files from Amazon S3.These files are encrypted using AWSKey Management Service (AWS KMS) keys.A solutions architect needs to design a solution that will ensure the required permissions are set correctly.Which combination of actions accomplish this? (Choose two.)Read More →
