A finance company hosts a data lake in Amazon S3.The company receives financial data records over SFTP each night from several third parties.The company runs its own SFTP server on an Amazon EC2 instance in a public subnet of a VPC.After the files are uploaded, they are moved to the data lake by a cron job that runs on the same instance.The SFTP server is reachable on DNS sftp.example.com through the use of Amazon Route 53.What should a solutions architect do to improve the reliability and scalability of the SFTP solution?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 →

A solutions architect is designing the data storage and retrieval architecture for a new application that a company will be launching soon.The application is designed to ingest millions of small records per minute from devices all around the world.Each record is less than 4 KB in size and needs to be stored in a durable location where it can be retrieved with low latency.The data is ephemeral and the company is required to store the data for 120 days only, after which the data can be deleted.The solutions architect calculates that, during the course of a year, the storage requirements would be about 10-15 TB.Which storage strategy is the MOST cost-effective and meets the design requirements?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 life sciences company is using a combination of open source tools to manage data analysis workflows and Docker containers running on servers in its on- premises data center to process genomics data.Sequencing data is generated and stored on a local storage area network (SAN), and then the data is processed.The research and development teams are running into capacity issues and have decided to re-architect their genomics analysis platform on AWS to scale based on workload demands and reduce the turnaround time from weeks to days.The company has a high-speed AWS Direct Connect connection.Sequencers will generate around 200 GB of data for each genome, and individual jobs can take several hours to process the data with ideal compute capacity.The end result will be stored in Amazon S3.The company is expecting 10-15 job requests each day.Which solution meets 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 is running a large containerized workload in the AWS Cloud.The workload consists of approximately 100 different services.The company usesAmazon 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 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 Solutions Architect is designing a deployment strategy for an application tier and has the following requirements:✑ The application code will need a 500 GB static dataset to be present before application startup.✑ The application tier must be able to scale up and down based on demand with as little startup time as possible.✑ The Development team should be able to update the code multiple times each day.✑ Critical operating system (OS) patches must be installed within 48 hours of being released.Which deployment strategy meets 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 →
