What does a registry contain for an organization?

The correct answer is that a registry in the context of an organization typically contains all images deployed by the organization. A registry serves as a centralized repository where various versions of software applications, including container images, are stored. This allows organizations to manage, distribute, and maintain their software images efficiently.

By maintaining a registry, organizations can ensure that they have a consistent and controlled environment for deploying applications. This is particularly critical in environments that utilize containerization, such as Docker, where images are essential for creating and running containers that encapsulate applications and their dependencies.

The other choices do not accurately reflect what a registry contains. While encryption algorithms may be a part of a security policy or system, they are not stored in a standard registry. A list of employees and their roles is typically found in human resources databases or management systems, not in a registry. Similarly, while a registry might keep logs of deployments or version histories, it does not typically track all network security incidents; that would be recorded in a different system, such as a security information and event management (SIEM) system.
