Exam AWS Certified Developer Associate topic 1 question 271 discussion

Exam question from Amazon's AWS Certified Developer Associate
Question #: 271
Topic #: 1
[All AWS Certified Developer Associate Questions]

A company is building a serverless microservice for an existing application that uses AWS Lambda functions and Amazon API Gateway. The microservice needs to automate an on-premises identity provider (IdP) that supports the OpenID Connect (OIDC) standard.

What should the company do to implement the API authorization mechanism with the LEAST operational overhead?

  • A. Use an API Gateway HTTP API to invoke the Lambda functions. Set the JSON Web Token (JWT) issuer as the public OIDC endpoint of the on-premises IdP.
  • B. Use an API Gateway HTTP API to invoke the Lambda functions. Create an Amazon Cognito identity pool. Create a federation between the identity pool and the on-premises IdP. Set the identity pool as the JSON Web Token (JWT) issuer.
  • C. Use an API Gateway REST API to invoke the Lambda functions. Configure the JSON Web Token (JWT) issuer to link to the on-premises IdP over the public internet.
  • D. Use an API Gateway REST API to invoke the Lambda functions. Create an Amazon Cognito identity pool. Create a federation between the identity pool and the on-premises IdP. Set Amazon Cognito as the authorizer.

The answer should be A. Only HTTP api support OpenID Connect. Also, API gateway does not integrated with Cognito Identity pool (in fact it is user pool)
