A financial services company loaded millions of historical stock trades into an Amazon DynamoDB table.The table uses on-demand capacity mode.Once each day at midnight, a few million new records are loaded into the table.Application read activity against the table happens in bursts throughout the day.and a limited set of keys are repeatedly looked up.The company needs to reduce costs associated with DynamoDB.Which strategy should a solutions architect recommend to meet this requirement?Read More →

An entertainment company recently launched a new game.To ensure a good experience for players during the launch period, the company deployed a static quantity of 12 r6g.16xlarge (memory optimized) Amazon EC2 instances behind a Network Load Balancer.The company’s operations team used the Amazon CloudWatch agent and a custom metric to include memory utilization in its monitoring strategy.Analysis of the CloudWatch metrics from the launch period showed consumption at about one quarter of the CPU and memory that the company expected.Initial demand for the game has subsided and has become more variable.The company decides to use an Auto Scaling group that monitors the CPU and memory consumption to dynamically scale the instance fleet.A solutions architect needs to configure the Auto Scaling group to meet demand in the most cost-effective way.Which solution will meet these requirements?Read More →

A team of data scientists is using Amazon SageMaker instances and SageMaker APIs to train machine learning (ML) models.The SageMaker instances are deployed in a VPC that does not have access to or from the internet.Datasets for ML model training are stored in an Amazon S3 bucket.Interface VPC endpoints provide access to Amazon S3 and the SageMaker APIs.Occasionally, the data scientists require access to the Python Package Index (PyPI) repository to update Python packages that they use as part of their workflow.A solutions architect must provide access to the PyPI repository while ensuring that the SageMaker instances remain isolated from the internet.Which solution will meet these requirements?Read More →

A company wants to migrate its website to AWS.The website uses containers that are deployed in an on-premises, self-managed Kubernetes cluster.All data for the website is stored in an on-premises PostgreSQL database.The company has decided to migrate the on-premises Kubernetes cluster to an Amazon Elastic Kubernetes Service (Amazon EKS) cluster.The EKS cluster will use EKS managed node groups with a static number of nodes.The company will also migrate the on-premises database to an Amazon RDS for PostgreSQL database.A solutions architect needs to estimate the total cost of ownership (TCO) for this workload before the migration.Which solution will provide the required TCO information?Read More →

A company has more than 10,000 sensors that send data to an on-premises Apache Kafka server by using the Message Queuing Telemetry Transport (MQTT) protocol.The on-premises Kafka server transforms the data and then stores the results as objects in an Amazon S3 bucket.Recently, the Kafka server crashed.The company lost sensor data while the server was being restored.A solutions architect must create a new design on AWS that is highly available and scalable to prevent a similar occurrence.Which solution will meet these requirements?Read More →

A company is migrating an application to the AWS Cloud.The application runs in an on-premises data center and writes thousands of images into a mounted NFS file system each night.After the company migrates the application, the company will host the application on an Amazon EC2 instance with a mounted Amazon Elastic File System (Amazon EFS) file system.The company has established an AWS Direct Connect connection to AWS.Before the migration cutover, a solutions architect must build a process that will replicate the newly created on-premises images to the EFS file system.What is the MOST operationally efficient way to replicate the images?Read More →

A company processes environmental data.The company has set up sensors to provide a continuous stream of data from different areas in a city.The data is available in JSON format.The company wants to use an AWS solution to send the data to a database that does not require fixed schemas for storage.The data must be sent in real time.Which solution will meet these requirements?Read More →

A company has developed a mobile game.The backend for the game runs on several virtual machines located in an on-premises data center.The business logic is exposed using a REST API with multiple functions.Player session data is stored in central file storage.Backend services use different API keys for throttling and to distinguish between live and test traffic.The load on the game backend varies throughout the day.During peak hours, the server capacity is not sufficient.There are also latency issues when fetching player session data.Management has asked a solutions architect to present a cloud architecture that can handle the game’s varying load and provide low-latency data access.The API model should not be changed.Which solution meets these requirements?Read More →

A company is running several applications in the AWS Cloud.The applications are specific to separate business units in the company.The company is running the components of the applications in several AWS accounts that are in an organization in AWS Organizations.Every cloud resource in the company’s organization has a tag that is named BusinessUnit.Every tag already has the appropriate value of the business unit name.The company needs to allocate its cloud costs to different business units.The company also needs to visualize the cloud costs for each business unit.Which solution will meet these requirements?Read More →

A software development company has multiple engineers who are working remotely.The company is running Active Directory Domain Services (AD DS) on an Amazon EC2 instance.The company’s security policy states that all internal, nonpublic services that are deployed in a VPC must be accessible through a VPN.Multi-factor authentication (MFA) must be used for access to a VPN.What should a solutions architect do to meet these requirements?Read More →
