A.

{ if( $input.params('integration') == 'mock' ) 'statusCode': 404 else 'statusCode': 500 end }

Answers
A.

{ if( $input.params('integration') == 'mock' ) 'statusCode': 404 else 'statusCode': 500 end }

B.

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

Answers
B.

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

C.

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

Answers
C.

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

D.

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

Suggested answer: D

Explanation:

Comprehensive Detailed Step by Step Explanation with All AWS Developer

Reference:

In this scenario, the developer is configuring a mock integration in API Gateway. The integration request mapping template allows you to map the incoming request data to a format that the API expects. For mock integration, it's common to return specific HTTP status codes based on the conditions.

Using $context.integration.status: The $context.integration.status variable refers to the status of the API Gateway integration, which is useful for generating responses based on the condition. Option D correctly uses this variable to determine the HTTP status code, returning 200 for a successful mock request or 500 for a failure.

Alternatives:

Options A, B, and C do not use the correct context variables for handling mock integrations. These options would not return the correct status codes based on the actual integration status.
