Sample Questions for Amazon DVA-C02 Exam Preparation

Question 1

A company is using Amazon API Gateway to invoke a new AWS Lambda function The company has Lambda function versions in its PROD and DEV environments. In each environment, there is a Lambda function alias pointing to the corresponding Lambda function version API Gateway has one stage that is configured to point at the PROD alias

The company wants to configure API Gateway to enable the PROD and DEV Lambda function versions to be simultaneously and distinctly available

Which solution will meet these requirements?

AEnable a Lambda authorizer for the Lambda function alias in API Gateway Republish PROD and create a new stage for DEV Create API Gateway stage variables for the PROD and DEV stages. Point each stage variable to the PROD Lambda authorizer to the DEV Lambda authorizer.

BSet up a gateway response in API Gateway for the Lambda function alias. Republish PROD and create a new stage for DEV. Create gateway responses in API Gateway for PROD and DEV Lambda aliases

CUse an environment variable for the Lambda function alias in API Gateway. Republish PROD and create a new stage for development. Create API gateway environment variables for PROD and DEV stages. Point each stage variable to the PROD Lambda function alias to the DEV Lambda function alias.

DUse an API Gateway stage variable to configure the Lambda function alias Republish PROD and create a new stage for development Create API Gateway stage variables for PROD and DEV stages Point each stage variable to the PROD Lambda function alias and to the DEV Lambda function alias

Correct : D

API Gateway Stages:Stages in API Gateway represent distinct environments (like PROD and DEV) allowing different configurations.

Stage Variables:Stage variables store environment-specific information, including Lambda function aliases.

Ease of Management:This solution offers a straightforward way to manage different Lambda function versions across environments.

Question 2

A developer is working on an ecommerce platform that communicates with several third-party payment processing APIs The third-party payment services do not provide a test environment.

The developer needs to validate the ecommerce platform's integration with the third-party payment processing APIs. The developer must test the API integration code without invoking the third-party payment processing APIs.

Which solution will meet these requirements'?

ASet up an Amazon API Gateway REST API with a gateway response configured for status code 200 Add response templates that contain sample responses captured from the real third-party API.

BSet up an AWS AppSync GraphQL API with a data source configured for each third-party API Specify an integration type of Mock Configure integration responses by using sample responses captured from the real third-party API.

CCreate an AWS Lambda function for each third-party API. Embed responses captured from the real third-party API. Configure Amazon Route 53 Resolver with an inbound endpoint for each Lambda function's Amazon Resource Name (ARN).

DSet up an Amazon API Gateway REST API for each third-party API Specify an integration request type of Mock Configure integration responses by using sample responses captured from the real third-party API

Correct : D

Mocking API Responses:API Gateway's Mock integration type enables simulating API behavior without invoking backend services.

Testing with Sample Data:Using captured responses from the real third-party API ensures realistic testing of the integration code.

Focus on Integration Logic:This solution allows the developer to isolate and test the application's interaction with the payment APIs, even without a test environment from the third-party providers.
