C is correct

'B' cannot be an option as there can be only 3 active Data Category Group at a time.

Data category visibility can be set with roles, permission sets, permission set groups, or profiles.

C is correct

Correct: B
Option B allows for the creation of separate data category groups for each division and assigns the respective category to a division profile. This approach ensures that each division only has access to its own articles when performing a search.

By using separate data category groups, Universal Containers can achieve the following:


Data Segregation: Each division can have its own set of articles organized under its designated data category group. This ensures that articles from one division are not accessible to another division during a search.



Access Control: By assigning the specific data category group to a division profile, Universal Containers can control access to the articles based on user profiles. Only users with the assigned division profile will be able to search and view the articles within their designated division.



Scalability: As Universal Containers has four internal divisions, creating separate data category groups allows for scalability and flexibility in managing articles for each division. It provides a structured and organized approach to categorize and maintain articles specific to each division.


Option A is not recommended because creating a sharing rule for each division to provide access using the role hierarchy may lead to complexity and potential maintenance challenges as the organization grows and the role hierarchy changes.

Option C suggests creating a single data category group for each division and providing access using the role hierarchy. However, this approach may not align with the requirement of ensuring that each division only has access to its own articles.

Option D suggests creating a sharing rule for each division to provide access based on criteria of the article. While this option could potentially restrict access, it may not be as efficient as using separate data category groups to achieve data segregation and control....
