Question # 4

A company manages a web application that runs on Amazon EC2 instances behind anApplication Load Balancer (ALB). The EC2 instances run in an Auto Scaling group acrossmultiple Availability Zones.

Launch a replica environment of everything except Amazon RDS in a differentAvailability Zone Create an RDS read replica in the new Availability Zone: and configurethe new stack to point to the local RDS DB instance. Add the new stack to the Route 53record set by using a hearth check to configure a failover routing policy.

C. Launch a replica environment of everything except Amazon RDS ma different AWSRegion. In the event of an outage copy and restore the latest RDS snapshot from theprimary. Region to the DR Region Adjust the Route 53 record set to point to the ALB in theDR Region.

D. Launch a replica environment of everything except Amazon RDS in a different AWSRegion. Create an RDS read replica in the new Region and configure the new environmentto point to the local RDS DB instance.

Question # 5

A company uses an Amazon API Gateway regional REST API to host its application API.The REST API has a custom domain. The REST API's default endpoint is deactivated.The company's internal teams consume the API. The company wants to use mutual TLSbetween the API and the internal teams as an additional layer of authentication.Which combination of steps will meet these requirements? (Select TWO.)

A. Use AWS Certificate Manager (ACM) to create a private certificate authority (CA).Provision a client certificate that is signed by the private CA.

B. Provision a client certificate that is signed by a public certificate authority (CA). Importthe certificate into AWS Certificate Manager (ACM).

C. Upload the provisioned client certificate to an Amazon S3 bucket. Configure the APIGateway mutual TLS to use the client certificate that is stored in the S3 bucket as the truststore.

D. Upload the provisioned client certificate private key to an Amazon S3 bucket. Configurethe API Gateway mutual TLS to use the private key that is stored in the S3 bucket as thetrust store.

E. Upload the root private certificate authority (CA) certificate to an Amazon S3 bucket.Configure the API Gateway mutual TLS to use the private CA certificate that is stored in theS3 bucket as the trust store.

Question # 6

A space exploration company receives telemetry data from multiple satellites. Smallpackets of data are received through Amazon API Gateway and are placed directly into anAmazon Simple Queue Service (Amazon SQS) standard queue. A custom application issubscribed to the queue and transforms the data into a standard format.Because of inconsistencies in the data that the satellites produce, the application isoccasionally unable to transform the data. In these cases, the messages remain in theSQS queue. A DevOps engineer must develop a solution that retains the failed messagesand makes them available to scientists for review and future processing.Which solution will meet these requirements?

A. Configure AWS Lambda to poll the SQS queue and invoke a Lambda function to checkwhether the queue messages are valid. If validation fails, send a copy of the data that is notvalid to an Amazon S3 bucket so that the scientists can review and correct the data. Whenthe data is corrected, amend the message in the SQS queue by using a replay Lambdafunction with the corrected data.

B. Convert the SQS standard queue to an SQS FIFO queue. Configure AWS Lambda topoll the SQS queue every 10 minutes by using an Amazon EventBridge schedule. Invokethe Lambda function to identify any messages with a SentTimestamp value that is olderthan 5 minutes, push the data to the same location as the application's output location, andremove the messages from the queue.

C. Create an SQS dead-letter queue. Modify the existing queue by including a redrivepolicy that sets the Maximum Receives setting to 1 and sets the dead-letter queue ARN tothe ARN of the newly created queue. Instruct the scientists to use the dead-letter queue toreview the data that is not valid. Reprocess this data at a later time.

D. Configure API Gateway to send messages to different SQS virtual queues that arenamed for each of the satellites. Update the application to use a new virtual queue for anydata that it cannot transform, and send the message to the new virtual queue. Instruct thescientists to use the virtual queue to review the data that is not valid. Reprocess this data ata later time.
