A company that runs applications on AWS recently subscribed to a new software-as-a-service (SaaS) data vendor.The vendor provides the data by way of aREST API that the vendor hosts in its AWS environment.The vendor offers multiple options for connectivity to the API and is working with the company to find the best way to connect.The company’s AWS account does not allow outbound internet access from its AWS environment.The vendor’s services run on AWS in the same Region as the company’s applications.A solutions architect must implement connectivity to the vendor’s API so that the API is highly available in the company’s VPC.Which solution will meet these requirements?Read More →

A company wants to run a custom network analysis software package to inspect traffic as traffic leaves and enters a VPC.The company has deployed the solution by using AWS CloudFormation on three Amazon EC2 instances in an Auto Scaling group.All network routing has been established to direct traffic to the EC2 instances.Whenever the analysis software stops working, the Auto Scaling group replaces an instance.The network routes are not updated when the instance replacement occurs.Which combination of steps will resolve this issue? (Choose three.)Read More →
A company’s infrastructure team is using AWS CloudFormation to deploy common infrastructure resources such as VPCs, subnets, Amazon RDS DB cluster endpoints, and Amazon DynamoDB tables for other teams to use.The CloudFormation templates also create AWS Systems Manager Parameter Store parameters to store information about these resources for application developers.The parameters include elements such as RDS DB cluster endpoints for clusters that the templates create.A developer creates a CloudFormation template that includes an AWS Lambda function that reads the SSM parameter value to access RDS DB cluster endpoints.The Lambda function has reserved concurrency configured to match the value of the Parameter Store maximum throughput (transactions per second) quota for the account and the AWS Region that hosts the account.The developer wants to prepare for a potential load increase.The developer expects the Lambda function’s concurrent invocation rate to be two times more than the Parameter Store maximum throughput quota value.Which solution will prepare for the load increase MOST cost-effectively?Read More →
