AWS Certified DevOps Engineer - Professional DOP-C02 — Topic 1 Question 197

Question

A company is refactoring applications to use AWS. The company identifies an internal web application that needs to make Amazon S3 API calls in a specific AWS account. The company wants to use its existing identity provider (IdP) auth.company.com for authentication. The IdP supports only OpenID Connect (OIDC). A DevOps engineer needs to secure the web application's access to the AWS account. Which combination of steps will meet these requirements? (Choose three.)

Accepted Answer

Correct answer: B, D, E. The correct answer is B, D, E. Option B: Create an IAM IdP by using the provider URL, audience, and signature from the existing IP. Option D: Create an IAM role that has a policy that allows the necessary S3 actions. Configure the role's trust policy to allow the OIDC IP to assume the role if the auth.company.com:aud context key is appid_from_idp. Option E: Configure the web application to use the AssumeRoleWithWebIdentity API operation to retrieve temporary credentials. Use the temporary credentials to make the S3 API calls. Amazon S3 provides durable, scalable object storage that is fully managed. An IAM role grants temporary, least-privilege permissions to AWS resources without long-term credentials. AWS IAM controls authenticated and authorized access to AWS resources with fine-grained policies.
