The Solutions Architect manages a serverless application that consists of multiple API gateways, AWS Lambda functions, Amazon S3 buckets, and AmazonDynamoDB tables.Customers say that a few application components slow while loading dynamic images, and some are timing out with the `504 GatewayTimeout` error.While troubleshooting the scenario, the Solutions Architect confirms that DynamoDB monitoring metrics are at acceptable levels.Which of the following steps would be optimal for debugging these application issues? (Choose two.)Read More →

A company is migrating a subset of its application APIs from Amazon EC2 instances to run on a serverless infrastructure.The company has set up Amazon APIGateway, AWS Lambda, and Amazon DynamoDB for the new application.The primary responsibility of the Lambda function is to obtain data from a third-partySoftware as a Service (SaaS) provider.For consistency, the Lambda function is attached to the same virtual private cloud (VPC) as the original EC2 instances.Test users report an inability to use this newly moved functionality, and the company is receiving 5xx errors from API Gateway.Monitoring reports from the SaaS provider shows that the requests never made it to its systems.The company notices that Amazon CloudWatch Logs are being generated by the Lambda functions.When the same functionality is tested against the EC2 systems, it works as expected.What is causing the issue?Read More →

A company is migrating a legacy application from an on-premises data center to AWS.The application consists of a single application server and a Microsoft SQLServer database server.Each server is deployed on a VMware VM that consumes 500 TB of data across multiple attached volumes.The company has established a 10 Gbps AWS Direct Connect connection from the closest AWS Region to its on-premises data center.The Direct Connect connection is not currently in use by other services.Which combination of steps should a solutions architect take to migrate the application with the LEAST amount of downtime? (Choose two.)Read More →

A company has an application that sells tickets online and experiences bursts of demand every 7 days.The application has a stateless presentation layer running on Amazon EC2, an Oracle database to store unstructured data catalog information, and a backend API layer.The front-end layer uses an Elastic Load Balancer to distribute the load across nine On-Demand instances over three Availability Zones (AZs).The Oracle database is running on a single EC2 instance.The company is experiencing performance issues when running more than two concurrent campaigns.A solutions architect must design a solution that meets the following requirements:✑ Address scalability issues.✑ Increase the level of concurrency.✑ Eliminate licensing costs.✑ Improve reliability.Which set of steps should the solutions architect take?Read More →

A company that provisions job boards for a seasonal workforce is seeing an increase in traffic and usage.The backend services run on a pair of Amazon EC2 instances behind an Application Load Balancer with Amazon DynamoDB as the datastore.Application read and write traffic is slow during peak seasons.Which option provides a scalable application architecture to handle peak seasons with the LEAST development effort?Read More →

A company has implemented an ordering system using an event driven architecture.During initial testing, the system stopped processing orders.Further log analysis revealed that one order message in an Amazon Simple Queue Service (Amazon SQS) standard queue was causing an error on the backend and blocking all subsequent order messages.The visibility timeout of the queue is set to 30 seconds, and the backend processing timeout is set to 10 seconds.A solutions architect needs to analyze faulty order messages and ensure that the system continues to process subsequent messages.Which step should the solutions architect take to meet these requirements?Read More →
