A company is configuring connectivity to a multi-account AWS environment to support application workloads that serve users in a single geographic region.The workloads depend on a highly available, on-premises legacy system deployed across two locations.It is critical for the AWS workloads to maintain connectivity to the legacy system, and a minimum of 5 Gbps of bandwidth is required.All application workloads within AWS must have connectivity with one another.Which solution will meet these requirements?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 →

A company wants to migrate a 30 TB Oracle data warehouse from on premises to Amazon Redshift.The company used the AWS Schema Conversion Tool (AWSSCT) to convert the schema of the existing data warehouse to an Amazon Redshift schema.The company also used a migration assessment report to identify manual tasks to complete.The company needs to migrate the data to the new Amazon Redshift cluster during an upcoming data freeze period of 2 weeks.The only network connection between the on-premises data warehouse and AWS is a 50 Mbps internet connection.Which migration strategy meets these requirements?Read More →

A large company has a business-critical application that runs in a single AWS Region.The application consists of multiple Amazon EC2 instances and an AmazonRDS Multi-AZ DB instance.The EC2 instances run in an Amazon EC2 Auto Scaling group across multiple Availability Zones.A solutions architect is implementing a disaster recovery (DR) plan for the application.The solutions architect has created a pilot light application deployment in a new Region, which is referred to as the DR Region.The DR environment has an Auto Scaling group with a single EC2 instance and a read replica of the RDS DB instance.The solutions architect must automate a failover from the primary application environment to the pilot light environment in the DR Region.Which solution meets these requirements with the MOST operational efficiency?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 →

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 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 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 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 →

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 →
