The developer uses the AWS Serverless Application Model (AWS SAM) to build and run serverless applications on AWS. Each time the developer pushes of changes for only to the Lambda functions, all the artifacts in the application are rebuilt.
The developer wants to implement AWS SAM Accelerate by running a command to only redeploy the Lambda functions that have changed.
Which command will meet these requirements?
A developer must cache dependent artifacts from Maven Central, a public package repository, as part of an application's build pipeline. The build pipeline has an AWS CodeArtifact repository where artifacts of the build are published. The developer needs a solution that requires minimum changes to the build pipeline.
Which solution meets these requirements?
A company regularly receives route status updates from its delivery trucks as events in Amazon EventBridge. The company is building an API-based application in a VPC that will consume and process the events to create a delivery status dashboard. The API application must not be available by using public IP addresses because of security and compliance requirements.

Which solution will meet these requirements?
A company has deployed an application on AWS Elastic Beanstalk.

What is the MOST cost-effective way to solve the deployment issue?
A company is building a scalable data management solution by using AWS services to improve the speed and agility of development. The solution will ingest large volumes of data from various sources and will process this data through multiple business rules and transformations.
The solution requires business rules to run in sequence and to handle reprocessing of data if errors occur when the business rules run. The company needs the solution to be scalable and to require the least possible maintenance.
Which AWS service should the company use to manage and automate the orchestration of the data flows to meet these requirements?
A developer is using AWS CodeDeploy to launch an application onto Amazon EC2 instances. The application deployment fails during testing. The developer notices an IAM_ROLE_PERMISSIONS error code in Amazon CloudWatch logs.
