Question 6. A company wants to implement a data lake in the AWS Cloud. The company must ensure that only specific teams have access to sensitive data in the data lake. The company must have row-level access control for the data lake. Options:
A. Use Amazon RDS to store the data. Use IAM roles and permissions for data governance and access control.
B. Use Amazon Redshift to store the data. Use IAM roles and permissions for data governance and access control.
C. Use Amazon S3 to store the data. Use AWS Lake Formation for data governance and access control.
D. Use AWS Glue Catalog to store the data. Use AWS Glue DataBrew for data governance and access control.

Question 7. A company is building an ecommerce web service on AWS. The web service sends information about new orders to an Amazon API Gateway REST API for processing. The company wants to eliminate duplicate orders within a 5-minute processing window. Which solution will meet this requirement with the LEAST amount of development effort?
A. Configure API Gateway to send a message to an Amazon SNS topic when API Gateway receives an order. Create a filter policy for the SNS topic to deduplicate orders. Subscribe an AWS Lambda function to the SNS topic to process filtered results.
B. Configure API Gateway to send a message to an Amazon SQS FIFO queue when API Gateway receives an order. Include a MessageDeduplicationId token in the order requests. Configure the queue to invoke an AWS Lambda function for processing.
C. Use API Gateway integrations to send messages to an Amazon SQS standard queue. Include OrderID and Timestamp attributes in the order requests. Use an AWS Lambda function to consume the queue. Use the attributes to discard duplicate orders.
D. Use an API Gateway integration to send messages to an Amazon SQS standard queue. Configure an AWS Lambda function to process the queue. Include a MessageDeduplicationId token in the order requests.

Question 8. A company hosts a photo sharing web application on AWS. Users upload and share thousands of photos each hour. The company needs a durable storage solution that provides retrieval mechanisms for the photos. Most uploaded photos are not accessed often after 30 days, but the company does not want to delete older photos. Which solution will meet these requirements in the MOST cost-effective way?
A. Store the photos in an Amazon EFS file system for immediate use. Use AWS Backup with on- demand backups and point-in-time recovery PITR to store photos that are older than 30 days.
B. Store the photos in an Amazon S3 bucket. Use Amazon S3 Lifecycle configurations to move photos that are older than 30 days to S3 Intelligent-Tiering.
C. Store the photos in Amazon DynamoDB for immediate use. Use AWS Backup with on-demand backups and point-in-time recovery PITR to store photos that are older than 30 days.
D. Store the photos in Amazon FSx for Lustre for immediate use. Use AWS Backup with continuous backups and point-in-time recovery PITR to store photos that are older than 30 days.

Question 9. A company is building a new application that uses multiple serverless architecture components. The application architecture includes an Amazon API Gateway REST API and AWS Lambda functions to manage incoming requests. The company needs a service to send messages that the REST API receives to multiple target Lambda functions for processing. The service must filter messages so each target Lambda function receives only the messages the function needs. Which solution will meet these requirements with the LEAST operational overhead?
A. Send the requests from the REST API to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe multiple Amazon Simple Queue Service (Amazon SQS) queues to the SNS topic. Configure the target Lambda functions to poll the SQS queues.
B. Send the requests from the REST API to a set of Amazon EC2 instances that are configured to process messages. Configure the instances to filter messages and to invoke the target Lambda functions.
C. Send the requests from the REST API to Amazon Managed Streaming for Apache Kafka (Amazon MSK). Configure Amazon MSK to publish the messages to the target Lambda functions.
D. Send the requests from the REST API to multiple Amazon Simple Queue Service (Amazon SQS) queues. Configure the target Lambda functions to poll the SQS queues.

Question 10. A company has an on-premises application that uses SFTP to collect financial data from multiple vendors. The company is migrating to the AWS Cloud. The company has created an application that uses Amazon S3 APIs to upload files from vendors. Some vendors run their systems on legacy applications that do not support S3 APIs. The vendors want to continue to use SFTP-based applications to upload data. The company wants to use managed services for the needs of the vendors that use legacy applications. Which solution will meet these requirements with the LEAST operational overhead?
A. Create an AWS Database Migration Service (AWS DMS) instance to replicate data from the storage of the vendors that use legacy applications to Amazon S3. Provide the vendors with the credentials to access the AWS DMS instance.
B. Create an AWS Transfer Family endpoint for vendors that use legacy applications.
C. Configure an Amazon EC2 instance to run an SFTP server. Instruct the vendors that use legacy applications to use the SFTP server to upload data.
D. Configure an Amazon S3 File Gateway for vendors that use legacy applications to upload files to an SMB file share.
