An application stack includes an Elastic Load Balancer in a public subnet, a fleet of Amazon EC2 instances in an Auto Scaling group, and an Amazon RDS MySQL cluster. Users connect to the application from the Internet. The application servers and database must be secure.
How should a Solutions Architect perform this task?

• A.Create a private subnet for the Amazon EC2 instances and a public subnet for the Amazon RDS cluster.
• B.Create a public subnet for the Amazon EC2 instances and a private subnet for the Amazon RDS cluster.
• C.Create a private subnet for the Amazon EC2 instances and a private subnet for the Amazon RDS cluster.
• D.Create a public subnet for the Amazon EC2 instances and a public subnet for the Amazon RDS cluster.

A company has a data ingestion workflow that consists the following:
* An Amazon Simple Notification Service (Amazon SNS) topic for notifications about new data deliveries
* An AWS Lambda function to process the data and record metadata
The company observes that the ingestion workflow fails occasionally because of network connectivity issues.
When such a failure occurs, the Lambda function does not ingest the corresponding data unless the company manually reruns the job.
Which combination of actions should a solutions architect take to ensure that the Lambda function ingests all data in the future? (Select TWO.)

• A.Modify the Lambda function to read from an Amazon Simple Queue Service (Amazon SQS) queue
• B.Create an Amazon Simple Queue Service (Amazon SQS) queue, and subscribe It to me SNS topic.
• C.Configure the Lambda function In multiple Availability Zones.
• D.Increase provisioned throughput for the Lambda function.
• E.Increase the CPU and memory that are allocated to the Lambda function.

A company has applications that are deployed in multiple AWS Regions The applications use an architecture that is based on Amazon EC2, Amazon Elastic Block Store (Amazon EBS). Amazon Elastic File System (Amazon EFS) and Amazon DynamoDB The company lacks a mechanism for centralized data backup A solutions architect must centralize data backup with the least possible operational effort What should the solutions architect do to meet these requirements''

• A.Tag all resources by project Create backup plans in AWS Backup to back up the data by tag name according to each project's needs
• B.Tag all resources by project Create an AWS Lambda function to run on schedule and take snapshots of each EC2 instance, EBS volume and EFS file system by project Configure the function to invoke DynamoDB on-demand backup
• C.Tag all resources by project Use AWS Systems Manager to set up snapshots by project and set DynamoDB incremental backups
• D.Use AWS CloudFormation to create a template for every new project so that all resources can be recreated at any time Set the template to take daily snapshots of each EC2 instance, EBS volume and EFS file system Set the template to use DynamoDB on-demand backup for daily backups.

A company has developed a custom tool used in its workflow that runs within a Docker container. The company must perform manual steps each time the container code is updated to make the container image available to new workflow executions. The company wants to automate this process to eliminate manual effort and ensure a new container image is generated every time the tool code is updated.
Which combination of actions should a solutions architect take to meet these requirements? (Choose three.)

• A.Configure an AWS CodePipeline pipeline that sources the tool code from the AWS CodeCommit repository and initiates an AWS CodeBuild build.
• B.Configure an Amazon ECR repository for the tool. Configure an AWS CodeCommit repository containing code for the tool being deployed to the container image in Amazon ECR.
• C.Configure an AWS CodeDeploy application that triggers an application version update that pulls the latest tool container image from Amazon ECR, updates the container with code from the source AWS CodeCommit repository, and pushes the updated container image to Amazon ECR.
• D.Configuration an AWS CodeBuild project that pulls the latest tool container image from Amazon ECR, updates the container with code from the source AWS CodeCommit repository, and pushes the updated container image to Amazon ECR.
• E.Configure an AWS CodePipeline pipeline that sources the tool code from the AWS CodeCommit repository and initiates an AWS CodeDeploy application update.
• F.Configure an Amazon EventBridge rule that triggers on commits to the AWS CodeCommit repository for the tool. Configure the event to trigger an update to the tool container image in Amazon ECR. Push the updated container image to Amazon ECR.

True or false: In a CloudFormation template, you can reuse the same logical ID several times to reference the resources in other parts of the template.

• A.True, a logical ID can be used several times to reference the resources in other parts of the template.
• B.False, a logical ID must be unique within the template.
• C.False, you can mention a resource only once and you cannot reference it in other parts of a template.
• D.False, you cannot reference other parts of the template.
