A company is currently in the design phase of an application that will need an RPO of less than 5 minutes and an RTO of less than 10 minutes.The solutions architecture team is forecasting that the database will store approximately 10 TB of data.As part of the design, they are looking for a database solution that will provide the company with the ability to fail over to a secondary Region.Which solution will meet these business requirements at the LOWEST cost?Read More →

A company owns a chain of travel agencies and is running an application in the AWS Cloud.Company employees use the application to search for information about travel destinations.Destination content is updated four times each year.Two fixed Amazon EC2 instances serve the application.The company uses an Amazon Route 53 public hosted zone with a multivalue record of travel.example.com that returns the Elastic IP addresses for the EC2 instances.The application uses Amazon DynamoDB as its primary data store.The company uses a self-hosted Redis instance as a caching solution.During content updates, the load on the EC2 instances and the caching solution increases drastically.This increased load has led to downtime on several occasions.A solutions architect must update the application so that the application is highly available and can handle the load that is generated by the content updates.Which solution will meet these requirements?Read More →

A company needs to store and process image data that will be uploaded from mobile devices using a custom mobile app.Usage peaks between 8 AM and 5 PM on weekdays, with thousands of uploads per minute.The app is rarely used at any other time.A user is notified when image processing is complete.Which combination of actions should a solutions architect take to ensure image processing can scale to handle the load?

A company is collecting a large amount of data from a fleet of IoT devices.Data is stored as Optimized Row Columnar (ORC) files in the Hadoop Distributed File System (HDFS) on a persistent Amazon EMR cluster.The company’s data analytics team queries the data by using SQL in Apache Presto deployed on the same EMR cluster.Queries scan large amounts of data, always run for less than 15 minutes, and run only between 5 PM and 10 PM.The company is concerned about the high cost associated with the current solution.A solutions architect must propose the most cost-effective solution that will allow SQL data queries.Which solution will meet these requirements?Read More →

A company has a website that runs on four Amazon EC2 instances that are behind an Application Load Balancer (ALB).When the ALB detects that an EC2 instance is no longer available, an Amazon CloudWatch alarm enters the ALARM state.A member of the company’s operations team then manually adds a new EC2 instance behind the ALB.A solutions architect needs to design a highly available solution that automatically handles the replacement of EC2 instances.The company needs to minimize downtime during the switch to the new solution.Which set of steps should the solutions architect take to meet these requirements?Read More →

A company wants to manage the costs associated with a group of 20 applications that are infrequently used, but are still business-critical, by migrating to AWS.The applications are a mix of Java and Node.js spread across different instance clusters.The company wants to minimize costs while standardizing by using a single deployment methodology.Most of the applications are part of month-end processing routines with a small number of concurrent users, but they are occasionally run at other times.Average application memory consumption is less than 1 GB.though some applications use as much as 2.5 GB of memory during peak processing.The most important application in the group is a billing report written in Java that accesses multiple data sources and often runs for several hours.Which is the MOST cost-effective solution?Read More →

A company uses an organization in AWS Organizations to manage multiple AWS accounts.The company hosts some applications in a VPC in the company’s shared services account.The company has attached a transit gateway to the VPC in the shared services account.The company is developing a new capability and has created a development environment that requires access to the applications that are in the shared services account.The company intends to delete and recreate resources frequently in the development account.The company also wants to give a development team the ability to recreate the team’s connection to the shared services account as required.Which solution will meet these requirements?Read More →

A company has multiple lines of business (LOBs) that roll up to the parent company.The company has asked its solutions architect to develop a solution with the following requirements:• Produce a single AWS invoice for all of the AWS accounts used by its LOBs.• The costs for each LOB account should be broken out on the invoice.• Provide the ability to restrict services and features in the LOB accounts, as defined by the company’s governance policy.• Each LOB account should be delegated full administrator permissions, regardless of the governance policy.Which combination of steps should the solutions architect take to meet these requirements? (Choose two.)Read More →

A company has migrated an application from on premises to AWS.The application frontend is a static website that runs on two Amazon EC2 instances behind an Application Load Balancer (ALB).The application backend is a Python application that runs on three EC2 instances behind another ALB.The EC2 instances are large, general purpose On-Demand Instances that were sized to meet the on-premises specifications for peak usage of the application.The application averages hundreds of thousands of requests each month.However, the application is used mainly during lunchtime and receives minimal traffic during the rest of the day.A solutions architect needs to optimize the infrastructure cost of the application without negatively affecting the application availability.Which combination of steps will meet these requirements? (Choose two.)Read More →

A large company runs workloads in VPCs that are deployed across hundreds of AWS accounts.Each VPC consists of public subnets and private subnets that span across multiple Availability Zones.NAT gateways are deployed in the public subnets and allow outbound connectivity to the internet from the private subnets.A solutions architect is working on a hub-and-spoke design.All private subnets in the spoke VPCs must route traffic to the internet through an egress VPC.The solutions architect already has deployed a NAT gateway in an egress VPC in a central AWS account.Which set of additional steps should the solutions architect take to meet these requirements?Read More →
