Question 1

A company stores customer credit reports in an Amazon S3 bucket. An analytics service uses standardAmazon S3 GET requests to access the reports. A developer must implement a solution to redact personallyidentifiable information (PII) from the reports before the reports reach the analytics service.

A : Load the S3 objects into Amazon Redshift by using a COPY command. Implement dynamic data masking. Refactor the analytics service to read from Amazon Redshift.

B : Set up an S3 Object Lambda function. Attach the function to an S3 Object Lambda Access Point. Program the function to call a PII redaction API.

C : Use AWS Key Management Service (AWS KMS) to implement encryption in the S3 bucket. Re-upload all the existing S3 objects. Give the kms permission to the analytics service.

D : Create an Amazon Simple Notification Service (Amazon SNS) topic. Implement message data protection. Refactor the analytics service to publish data access requests to the SNS topic.

Answer: B

Question 2

A developer is updating an Amazon API Gateway REST API to have a mock endpoint. The developer wants to update the integration request mapping template so the endpoint will respond to mock integration requests with specific HTTP status codes based on various conditions.

A : { if( $input.params(‘integration’) == "mock" ) "statusCode": 404 else "statusCode": 500 end }

B : { if( $input.params('scope') == "internal" ) "statusCode": 200 else "statusCode": 500 end }

C : { if( $input.path("integration") ) "statusCode": 200 else "statusCode":404 end }

D : { if( $context.integration.status ) "statusCode": 200 else "statusCode": 500 end }

Answer: D

Question 3

A company follows collaborative development practices. The engineering manager wants to isolate the development effort by setting up simulations of API components owned by various development teams.

Which API integration type is best suited for this requirement?

A : AWS_PROXY

B : HTTP

C : MOCK

D : HTTP_PROXY

Answer: C

Question 4

company has a mobile app. The app includes an Amazon API Gateway REST API that invokes AWS Lambda functions. The Lambda functions process data from the app.

The company needs to test updated Lambda functions that have new features. The company must conduct these tests with a subset of users before deployment. The tests must not affect other users of the app.

Which solution will meet these requirements with the LEAST amount of operational effort?

A : Create a new version of each Lambda function with a weighted alias. Configure a weight value for each version of the Lambda function. Update the new weighted alias Amazon Resource Name (ARN) in the REST API.

B : Create a new REST API in API Gateway. Set up a Lambda proxy integration to connect to multiple Lambda functions. Enable canary settings on the deployment stage. Specify a smaller percentage of API traffic to go to the new version of the Lambda function.

C : Create a new version of each Lambda function. Integrate a predefined canary deployment in AWS CodeDeploy to slowly shift the traffic to the new versions automatically.

D : Create a new REST API in API Gateway. Set up a Lambda non-proxy integration to connect to multiple Lambda functions. Specify the necessary parameters and properties in API Gateway. Enable canary settings on the deployment stage. Specify a smaller percentage of API traffic to go to the new version of the Lambda function.
