What does the concept of 'Identity and Access Management (IAM)' involve in Google Cloud?

The concept of 'Identity and Access Management (IAM)' in Google Cloud specifically focuses on managing access to resources within the cloud environment. It involves the implementation of roles and permissions to control what actions users and groups can perform on various resources. IAM allows administrators to define who can access what resources and what levels of access or permissions they are granted, such as viewer, editor, or owner.

This capability is critical for maintaining security and governance within cloud environments, ensuring that only authorized users have appropriate access to sensitive resources. By properly configuring IAM roles, organizations can enforce the principle of least privilege, thereby reducing the risk of unauthorized access or actions within their Google Cloud infrastructure. This makes choice C the correct understanding of IAM's function in Google Cloud.
