  Which solution will meet these requirements?

  A. Use the EventBridge default event bus. Configure DynamoDB Streams for the DynamoDB table that hosts the customer order data.
  B. Create an EventBridge custom event bus. Create an AWS Lambda function as a target. Configure the Lambda function to forward the customer order data to the DynamoDB table.
  C. Create an EventBridge partner event bus. Create an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe an AWS Lambda function to the SNS topic. Configure the Lambda function to read the customer order data and to forward the data to the DynamoDB table.
  D. Create an EventBridge partner event bus. Create an AWS Lambda function as a target. Configure the Lambda function to forward the customer order data to the DynamoDB table.
  C. Create an EventBridge partner event bus. Create an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe an AWS Lambda function to the SNS topic. Configure the Lambda function to read the customer order data and to forward the data to the DynamoDB table.

  Explanation

  Amazon EventBridge supports routing application-generated events to AWS Lambda targets. The Lambda function can process and insert events into a DynamoDB table. This is a standard design pattern for connecting event-driven applications with DynamoDB. Option A confuses DynamoDB Streams (which streams changes from DynamoDB) with EventBridge (which is for event routing). Options C and D reference partner event buses, which are intended for SaaS integrations, not custom application events.

  Therefore, the correct and simplest solution is to use a custom EventBridge event bus with a Lambda target (B).

• Question 304:

  A company is creating an application. The company stores data from tests of the application in multiple on-premises locations.

  The company needs to connect the on-premises locations to VPCs in an AWS Region in the AWS Cloud.

  The number of accounts and VPCs will increase during the next year. The network architecture must simplify the administration of new connections and must provide the ability to scale.

  Which solution will meet these requirements with the LEAST administrative overhead?

  A. Create a peering connection between the VPCs. Create a VPN connection between the VPCs and the on-premises locations.
  B. Launch an Amazon EC2 instance. On the instance, include VPN software that uses a VPN connection to connect all VPCs and on-premises locations.
  C. Create a transit gateway. Create VPC attachments for the VPC connections. Create VPN attachments for the on-premises connections.
  D. Create an AWS Direct Connect connection between the on-premises locations and a central VPC. Connect the central VPC to other VPCs by using peering connections.
  C. Create a transit gateway. Create VPC attachments for the VPC connections. Create VPN attachments for the on-premises connections.

• Question 305:

  A company is designing a tightly coupled high performance computing (HPC) environment in the AWS Cloud. The company needs to include features that will optimize the HPC environment for networking and storage.

  Which combination of solutions will meet these requirements? (Choose two.)

  A. Create an accelerator in AWS Global Accelerator. Configure custom routing for the accelerator.
  B. Create an Amazon FSx for Lustre file system. Configure the file system with scratch storage.
  C. Create an Amazon CloudFront distribution. Configure the viewer protocol policy to be HTTP and HTTPS.
  D. Launch Amazon EC2 instances. Attach an Elastic Fabric Adapter (EFA) to the instances.
  E. Create an AWS Elastic Beanstalk deployment to manage the environment.
  B. Create an Amazon FSx for Lustre file system. Configure the file system with scratch storage.
  D. Launch Amazon EC2 instances. Attach an Elastic Fabric Adapter (EFA) to the instances.

• Question 306:

  A company has a service that produces event data. The company wants to use AWS to process the event data as it is received. The data is written in a specific order that must be maintained throughout processing. The company wants to implement a solution that minimizes operational overhead.

  How should a solutions architect accomplish this?

  A. Create an Amazon Simple Queue Service (Amazon SQS) FIFO queue to hold messages. Set up an AWS Lambda function to process messages from the queue.
  B. Create an Amazon Simple Notification Service (Amazon SNS) topic to deliver notifications containing payloads to process. Configure an AWS Lambda function as a subscriber.
  C. Create an Amazon Simple Queue Service (Amazon SQS) standard queue to hold messages. Set up an AWS Lambda function to process messages from the queue independently.
  D. Create an Amazon Simple Notification Service (Amazon SNS) topic to deliver notifications containing payloads to process. Configure an Amazon Simple Queue Service (Amazon SQS) queue as a subscriber.
  A. Create an Amazon Simple Queue Service (Amazon SQS) FIFO queue to hold messages. Set up an AWS Lambda function to process messages from the queue.

• Question 307:

  A company runs its critical storage application in the AWS Cloud. The application uses Amazon S3 in two AWS Regions.
