A company needs to architect a hybrid DNS solution.This solution will use an Amazon Route 53 private hosted zone for the domain cloud.example.com for the resources stored within VPCs.✑ The company has the following DNS resolution requirements:✑ On-premises systems should be able to resolve and connect to cloud.example.com.All VPCs should be able to resolve cloud.example.com.There is already an AWS Direct Connect connection between the on-premises corporate network and AWS Transit Gateway.Which architecture should the company use to meet these requirements with the HIGHEST performance?Read More →

A company plans to migrate many VMs from an on-premises environment to AWS.The company requires an initial assessment of the on-premises environment before the migration, a visualization of the dependencies between applications that run on the VMs, and a report that provides an assessment of the on-premises environment.To get this information, the company has initiated a Migration Evaluator assessment request.The company has the ability to install collector software in its on-premises environment without any constraintsWhich solution will provide the company with the required information with the LEAST operational overhead?Read More →

A company is running a serverless ecommerce application on AWS.The application uses Amazon API Gateway to invoke AWS Lambda Java functions.The Lambda functions connect to an Amazon RDS for MySQL database to store data.During a recent sale event, a sudden increase in web traffic resulted in poor API performance and database connection failures.The company needs to implement a solution to minimize the latency for the Lambda functions and to support bursts in traffic.Which solution will meet these requirements with the LEAST amount of change to the application?Read More →

A company has a serverless multi-tenant content management system on AWS.The architecture contains a web-based front end that interacts with an AmazonAPI Gateway API that uses a custom AWS Lambda authorizer.The authorizer authenticates a user to its tenant ID and encodes the information in a JSON WebToken (JWT) token.After authentication, each API call through API Gateway targets a Lambda function that interacts with a single Amazon DynamoDB table to fulfill requests.To comply with security standards, the company needs a stronger isolation between tenants.The company will have hundreds of customers within the first year.Which solution will meet these requirements with the LEAST operational overhead?Read More →

A company is developing a latency-sensitive application.Part of the application includes several AWS Lambda functions that need to initialize as quickly as possible.The Lambda functions are written in Java and contain initialization code outside the handlers to load libraries, initialize classes, and generate unique IDs.Which solution will meet the startup performance requirement MOST cost-effectively?Read More →

A company has a High Performance Computing (HPC) cluster in its on-premises data center, which runs thousands of jobs in parallel for one week every month, processing petabytes of images.The images are stored on a network file server, which is replicated to a disaster recovery site.The on-premises data center has reached capacity and has started to spread the jobs out over the course of the month in order to better utilize the cluster, causing a delay in the job completion.The company has asked its Solutions Architect to design a cost-effective solution on AWS to scale beyond the current capacity of 5,000 cores and 10 petabytes of data.The solution must require the least amount of management overhead and maintain the current level of durability.Which solution will meet the company’s requirements?Read More →

A company hosts an application that uses several Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer (ALB). During the initial startup of the EC2 instances, the EC2 instances run user data scripts to download critical content for the application from an Amazon S3 bucket.The EC2 instances are launching correctly. However, after a period of time, the EC2 instances are terminated with the following error message: “An instance was taken out of service in response to an ELB system health check failure.” EC2 instances continue to launch and be terminated because of Auto Scaling events in an endless loop.The only recent change to the deployment is that the company added a large amount of critical content to the S3 bucket. The company does not want to alter the user data scripts in production.What should a solutions architect do so that the production environment can deploy successfully?Read More →

A company is running a commercial Apache Hadoop cluster on Amazon EC2.This cluster is being used daily to query large files on Amazon S3.The data onAmazon S3 has been curated and does not require any additional transformations steps.The company is using a commercial business intelligence (BI) tool onAmazon EC2 to run queries against the Hadoop cluster and visualize the data.The company wants to reduce or eliminate the overhead costs associated with managing the Hadoop cluster and the BI tool.The company would like to move to a more cost-effective solution with minimal effort.The visualization is simple and requires performing some basic aggregation steps only.Which option will meet the company’s requirements?Read More →

A company needs to move some on-premises Oracle databases to AWS.The company has chosen to keep some of the databases on premises for business compliance reasons.The on-premises databases contain spatial data and run cron jobs for maintenance.The company needs to connect to the on-premises systems directly from AWS to query data as a foreign table.Which solution will meet these requirements?Read More →
