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 has an online shop that uses an Amazon API Gateway API, AWS Lambda functions, and an Amazon DynamoDB table provisioned with 900 RCUs.The API Gateway API receives requests from customers, and the Lambda functions handle the requests.Some of the Lambda functions read data from theDynamoDB table.During peak hours, customers are reporting timeout errors and slow performance.An investigation reveals that the Lambda functions that read the DynamoDB table occasionally time out.Amazon CloudWatch metrics show that the peak usage of the DynamoDB table is just below 900 RCUs.Which solution will resolve this issue MOST cost-effectively?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 has a large on-premises Apache Hadoop cluster with a 20 PB HDFS database.The cluster is growing every quarter by roughly 200 instances and 1PB.The company’s goals are to enable resiliency for its Hadoop data, limit the impact of losing cluster nodes, and significantly reduce costs.The current cluster runs 24/7 and supports a variety of analysis workloads, including interactive queries and batch processing.Which solution would meet these requirements with the LEAST expense and down time?Read More →

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 Solutions Architect is designing a multi-account structure that has 10 existing accounts.The design must meet the following requirements:✑ Consolidate all accounts into one organization.✑ Allow full access to the Amazon EC2 service from the master account and the secondary accounts.✑ Minimize the effort required to add additional secondary accounts.Which combination of steps should be included in the solution? (Choose two.)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’s compliance audit reveals that some Amazon Elastic Block Store (Amazon EBS) volumes that were created in an AWS account were not encrypted.A solutions architect must implement a solution to encrypt all new EBS volumes at rest.Which solution will meet this requirement with the LEAST effort?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 large industrial company has two AWS accounts.One account is for production, and one account is for development.The company manages the production account under its corporate organization in AWS Organizations.The development account is an isolated environment that developers use for testing.The company stores all the application configuration information in an Amazon S3 bucket in the production account.All developers in the development account are members of a single IAM group.A solutions architect must ensure that the developers can update the application configuration information in real time.What is the MOST operationally efficient solution that meets these requirements?Read More →
