Which of the following statements is true regarding the default features of Salesforce CMS app?

The statement regarding the support for 20 custom content types in the Salesforce CMS app is accurate because the platform is designed to help organizations create, manage, and publish content efficiently. The ability to define multiple custom content types allows users to tailor the CMS to fit their specific content needs and use cases. This flexibility is crucial for businesses that require varied types of content, such as articles, images, videos, and other formats.

While other statements may contain elements of truth about the CMS app, they do not fully align with its default features. For instance, the CMS app does not offer unlimited content storage, so it has specific limits depending on the organization's plan. Additionally, user access is also limited by the licensing agreements, and the assumption of unlimited access is incorrect. Furthermore, the CMS is not restricted to exclusively hosting public content; it can facilitate both private and public content sharing based on user permissions and settings.

Thus, recognizing the support for a defined number of custom content types not only highlights the app's capabilities but also aligns with its intended strategic use within organizations.
