Answers
D.
Use roles that allow a web identity federated user to assume a role that allows access to the Redshift table by providing temporary credentials.
Suggested answer: D

Explanation:

The AWS Documentation mentions the following

"When you write such an app, you'll make requests to AWS services that must be signed with an AWS access key. However, we strongly recommend that you do not embed or distribute long-term AWS credentials with apps that a user downloads t device, even in an encrypted store. Instead, build your app so that it requests temporary AWS security credentials dynamica when needed using web identify federation. The supplied temporary credentials map to an AWS role that has only the permissioi needed to perform the tasks required by the mobile app".

Option A.B and C are all automatically incorrect because you need to use IAM Roles for Secure access to services For more information on web identity federation please refer to the below Link: http://docs.aws.amazon.com/IAM/latest/ UserGuide/id_roles_providers_oidc.html The correct answer is: Use roles that allow a web identity federated user to assume a role that allows access to the RedShift table by providing temporary credentials.
