• Question 701:

  A company runs a shopping application lhat uses Amazon DynamoDB to store customer information. In case of data corruption, a solutions architect needs to design a solution that meets a recovery point objective (RPO) of 15 minutes and a recovery time objective (RTO> of 1 hour.

  What should the solutions architect recommend to meet these requirements?

  A. Configure DynamoDB global tables. For RPO recovery, point the application to a different AWS Region.
  B. Configure DynamoDB point-in-time recovery. For RPO recovery, restore to the desired point in time.
  C. Export the DynamoDB data to Amazon S3 Glacier on a daily basis. For RPO recovery, import the data from S3 Glacier to DynamoDB.
  D. Schedule Amazon Elastic Block Store (Amazon EBS) snapshots for the DynamoDB table every 15 minutes. For RPO recovery, restore the DynamoDB table by using the EBS snapshot.
  B. Configure DynamoDB point-in-time recovery. For RPO recovery, restore to the desired point in time.

• Question 702:

  A solutions architect is designing the architecture for a software demonstration environment. The environment will run on Amazon EC2 instances in an Auto Seating group bel (ALB). The system will experience significant increases in traffic during working hours but is not required to operate on weekends.

  A. Use AWS Auto Scaling to adjust the ALB capacity based on request rate.
  B. Use AWS Auto Scaling to scale the capacity of the VPC internet gateway.
  C. Launch the EC2 instances in multiple AWS Regions to distribute the load across Regions.
  D. Use a target tracking scaling policy to scale the Auto Scaling group based on instance CPU utilization.
  E. Use scheduled scaling to change the Auto Scaling group minimum, maximum, and desired capacity to zero for weekends. Revert to the default values at the start of

• Question 703:

  A company is deploying an application in three AWS Regions using an Application Load Balancer Amazon Route 53 will be used to distribute traffic between these Regions. Which Route 53 configuration should a solutions architect use to provide the MOST high-performing experience?

• Question 704:

  A development team is creating an event-based application that uses AWS Lambda functions. Events will be generated when files are added to an Amazon S3 bucket. The development team currently has Amazon Simple Notification Service (Amazon SNS) configured as the event target from Amazon S3.

  What should a solution architect do to process the events from Amazon S3 in a scalable way?

  A. Create an SNS subscription that processes the event in Amazon Elastic Container Service (Amazon ECS) before the event runs in Lambda.
  B. Create an SNS subscription that processes the event in Amazon Elastic Kubermetes Service (Amazon EKS) before the event runs in Lambda.
  C. Create on SNS subscription that sends the event to AWS Server Migration Service (AWS SQS).Configure the SQS queue to trigger a Lambda function.
  D. Create an SNS subscription that sends the event to AWS Server Migration Service (AWS SMS).Configure the Lambda function to poll from the SMS event
  D. Create an SNS subscription that sends the event to AWS Server Migration Service (AWS SMS).Configure the Lambda function to poll from the SMS event

• Question 705:

  A company hosts an application on an AWS Lambda function that runs a number of processing steps The Lambda function typically takes less than 5 minutes to run unless errors occur The company needs to decouple the application code because of past errors that caused the whole process to fail when a processing step took longer than expected The processing steps must be available to be replayed up to 12 months from when the onginal processing occurred

  How should a solutions architect design the new solution1?

  A. Configure Amazon EventBridge (Amazon CloudWatch Events), and create an archive Split the processes into separate Lambda functions Create rules for the different event patterns from the Lambda functions to perform processing
  B. Keep the Lambda function in place, but increase the timeout to 15 minutes Configure the Lambda function to write each processing step into an Amazon DynamoDB table Replay the steps by using a separate Lambda function and by querying the table when necessary
  C. Keep the Lambda function in place, but increase the timeout to 60 minutes. Configure the Lambda function to write each processing step into a daily file in an Amazon S3 bucket Replay the steps by using a separate Lambda function and by querying the file based on required date
  D. Configure Amazon Simple Queue Service (Amazon SQS) queues, and create an archive Split the processes into separate Lambda functions Pass messages to different queues as each process is completed, and invoke the next Lambda function to poll the queue for new messages Replay the messages from the SQL queue archive when necessary
  D. Configure Amazon Simple Queue Service (Amazon SQS) queues, and create an archive Split the processes into separate Lambda functions Pass messages to different queues as each process is completed, and invoke the next Lambda function to poll the queue for new messages Replay the messages from the SQL queue archive when necessary

• Question 706:

  A company runs an AWS Lambda function in private subnets in a VPC The subnets have a default route to the internet through an Amazon EC2 NAT instance The Lambda function processes input data and saves its output as an object to Amazon S3 intermittently the Lambda function times out while trying to upload the object because of saturated traffic on the NAT instance's network The company wants to access Amazon S3 without traversing the internet

  Which solution will meet these requirements'

  A. Replace the fcC2 NAT instance with an AWS managed NAT gateway
  B. Increase the size of the EC2 NAT instance in the VPC to a network optimized instance type
  C. Provision a gateway endpoint for Amazon S3 in the VPC Update the route tables of the subnets accordingly
  D. Provision a transit gateway Place transit gateway attachments in the private subnets where the Lambda function is running
  C. Provision a gateway endpoint for Amazon S3 in the VPC Update the route tables of the subnets accordingly

• Question 707:

  A company wants to move from many standalone AWS accounts to a consolidated, multi- account architecture. The company plans to create many new AWS accounts for different business units The company needs to authenticate access to these AWS accounts by using a centralized corporate directory service

  Which combination of actions should a solutions architect recommend to meet these requirements? (Select TWO )

  A. Create a new organization in AWS Organizations with all features turned on Create the new AWS accounts in the organization
  B. Set up an Amazon Cognito identity pool Configure AWS Single Sign-On to accept Amazon Cognito authentication
  C. Configure a service control policy (SCP) to manage the AWS accounts Add AWS Single Sign-On to AWS Directory Service
  D. Create a new organization in AWS Organizations Configure the organization's authentication mechanism to use AWS Directory Service directly
  E. Set up AWS Single Sign-On (AWS SSO) in the organization Configure AWS SSO and integrate it with the company's corporate directory service
  A. Create a new organization in AWS Organizations with all features turned on Create the new AWS accounts in the organization
