A company has a website that runs on Amazon EC2 instances behind an Application Load Balancer (ALB).The instances are in an Auto Scaling group.The ALB is associated with an AWS WAF web ACL.The website often encounters attacks in the application layer.The attacks produce sudden and significant increases in traffic on the application server.The access logs show that each attack originates from different IP addresses.A solutions architect needs to implement a solution to mitigate these attacks.Which solution will meet these requirements with the LEAST operational overhead?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 runs a web application on AWS.The web application delivers static content from an Amazon S3 bucket that is behind an Amazon CloudFront distribution.The application serves dynamic content by using an Application Load Balancer (ALB) that distributes requests to a fleet of Amazon EC2 instances in Auto Scaling groups.The application uses a domain name setup in Amazon Route 53.Some users reported occasional issues when the users attempted to access the website during peak hours.An operations team found that the ALB sometimes returned HTTP 503 Service Unavailable errors.The company wants to display a custom error message page when these errors occur.The page should be displayed immediately for this error code.Which solution will meet these requirements with the LEAST operational overhead?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 financial services company loaded millions of historical stock trades into an Amazon DynamoDB table.The table uses on-demand capacity mode.Once each day at midnight, a few million new records are loaded into the table.Application read activity against the table happens in bursts throughout the day.and a limited set of keys are repeatedly looked up.The company needs to reduce costs associated with DynamoDB.Which strategy should a solutions architect recommend to meet this requirement?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 →
