Which of the following is an example of an Expansion Module?

An Expansion Module is a component that enhances the functionality of a system by adding new features, capabilities, or configurations. The IAM, or Identity Access Management, is designed to manage user identities and their access rights across various applications and systems. As an Expansion Module, IAM allows organizations to implement more robust security measures, improve user management, and streamline access control, which is crucial in a modern IT environment.

In contrast, other options like CSM (Customer Service Management), ASM (Application Service Management), and LSM (Lifecycle Service Management) serve different purposes that are not primarily focused on expanding the management of identities and access rights. While they each provide valuable functions within an organization's operational framework, they do not fall under the category of Expansion Modules like IAM does. Thus, IAM is the clear example of an Expansion Module.
