Question 108

A company maintains its accounting records in a custom application that runs on Amazon EC2 instances. The company needs to migrate the data to an AWS managed service for development and maintenance of the application data. The solution must require minimal operational support and provide immutable, cryptographically verifiable logs of data changes.

Which solution will meet these requirements MOST cost-effectively?

Options:

Copy the records from the application into an Amazon Redshift cluster.

Copy the records from the application into an Amazon Neptune cluster.

Copy the records from the application into an Amazon Timestream database.

Copy the records from the application into an Amazon Quantum Ledger Database (Amazon QLDB) ledger.

Question 109

A company collects data from sensors. The company needs a cloud-based solution to store and transform the sensor data to make critical decisions. The solution must store the data for up to 2 days. After 2 days, the solution must delete the data. The company needs to use the transformeddata in an automated workflow that has manual approval steps.

Which solution will meet these requirements?

Options:

Load the data into an Amazon Simple Queue Service (Amazon SQS) queue that has a retention period of 2 days. Use an Amazon EventBridge pipe to retrieve data from the queue, transform the data, and pass the data to an AWS Step Functions workflow.

Load the data into AWS DataSync. Delete the DataSync task after 2 days. Invoke an AWS Lambda function to retrieve the data, transform the data, and invoke a second Lambda function that performs the remaining workflow steps.

Load the data into an Amazon Simple Notification Service (Amazon SNS) topic. Use an Amazon EventBridge pipe to retrieve the data from the topic, transform the data, and send the data to Amazon EC2 instances to perform the remaining workflow steps.

Load the data into an Amazon Simple Notification Service (Amazon SNS) topic. Use an Amazon EventBridge pipe to retrieve the data from the topic and transform the data into an appropriate format for an Amazon SQS queue. Use an AWS Lambda function to poll the queue to perform the remaining workflow steps.

Question 110

A company runs a web application on Amazon EC2 instances in an Auto Scaling group that has a target group. The company designed the application to work with session affinity (sticky sessions) for a better user experience.

The application must be available publicly over the internet as an endpoint. A WAF must be applied to the endpoint for additional security. Session affinity (sticky sessions) must be configured on the endpoint.

Options:

Create a public Network Load Balancer. Specify the application target group.

Create a Gateway Load Balancer. Specify the application target group.

Create a public Application Load Balancer. Specify the application target group.

Create a second target group. Add Elastic IP addresses to the EC2 instances.

Create a web ACL in AWS WAF. Associate the web ACL with the endpoint.

Question 111

A company is building a serverless application that processes large volumes of data from a mobile app. The application uses an AWS Lambda function to process the data and store the data in an Amazon DynamoDB table.

The company needs to ensure that the application can recover from failures and continue processing data without losing any records.

Which solution will meet these requirements?

Options:

Configure the Lambda function to use a dead-letter queue with an Amazon Simple Queue Service (Amazon SQS) queue. Configure Lambda to retry failed records from the dead-letter queue. Use a retry mechanism by implementing an exponential backoff algorithm.

Configure the Lambda function to read records from Amazon Data Firehose. Replay the Firehose records in case of any failures.

Use Amazon OpenSearch Service to store failed records. Configure AWS Lambda to retry failed records from OpenSearch Service. Use Amazon EventBridge to orchestrate the retry logic.

Use Amazon Simple Notification Service (Amazon SNS) to store the failed records. Configure Lambda to retry failed records from the SNS topic. Use Amazon API Gateway to orchestrate the retry calls.
