AWS Identity and Access Management (IAM)

Answer - B.

The AWS Documentation mentions the following:

AWS Identity and Access Management (IAM) is a web service that helps you control access to AWS resources securely.

You use IAM to control who is authenticated (signed in) and authorized (has permissions) to use resources.

The correct answer is B. AWS IAM (Identity and Access Management).

AWS IAM is a web service that helps you securely control access to AWS resources. You can use IAM to manage users (individuals who interact with AWS), groups (collections of users), and permissions (which determine what actions users and groups can perform on specific resources).

With IAM, you can create and manage users and groups, assign and manage permissions, and create and manage roles, which allow temporary access to resources for tasks such as automated deployments or accessing resources across AWS accounts. IAM also integrates with many AWS services, enabling you to control access to resources across your entire AWS infrastructure.

AWS Config is a service that provides a detailed view of the configuration of AWS resources in your account. It enables you to audit, evaluate, and assess the configurations of your resources to ensure compliance with your organizational policies and industry standards. AWS Trusted Advisor is a service that provides recommendations to help optimize your AWS infrastructure for performance, security, cost, and fault tolerance.

AWS, on the other hand, refers to Amazon Web Services, which is a cloud computing platform that provides a wide range of services, including computing, storage, databases, analytics, networking, machine learning, and more. AWS is not specifically designed to manage identities, but rather to provide a comprehensive platform for building and running applications and services in the cloud.
