After importing IBM Knowledge Accelerator assets, which are a collection of governance artifacts, they are organized into predefined categories within IBM Watson Knowledge Catalog. By default, only the user who performs the import has access to these artifacts. To enable other users to view, use, and manage these assets, they must be explicitly granted permissions. This is accomplished by adding them as collaborators to the top-level Knowledge Accelerators categories. Assigning them a role (e.g., Viewer, Editor, Admin) within the category defines their level of access to the contained artifacts.

A. Ensure a shared credential has been configured.

Shared credentials are used for connecting to data sources, not for managing user access to governance artifacts like business terms or data classes.

B. Add users to the Knowledge Accelerators security group.

There is no default "Knowledge Accelerators security group." While user groups can be added as collaborators, the fundamental action is assigning collaborators to categories, not managing a specific, predefined group.

D. Ensure the user permission role is active.

A user must have an active platform role to access the system, but this does not automatically grant them permission to specific, newly imported governance artifacts. Access is granularly controlled at the category level.

"Setting up access to Knowledge Accelerators."

Section: "Setting up access to Knowledge Accelerators"

Content: "After you import the Knowledge Accelerator content

you must configure who can use the categories. Without being added as a collaborator to the Knowledge Accelerator categories

only the user who imports the content can see and use the artifacts. To grant other users permissions to Knowledge Accelerator categories

add collaborators to the categories." This directly supports that adding collaborators is the required step.

2. IBM Cloud Pak for Data 4.8 Documentation

"Managing access to a category."

Section: "Category collaborators"

Content: "You control which users can view or manage a category and its artifacts by adding users and user groups as collaborators. You assign each collaborator a category role

which controls their permissions." This explains the mechanism for controlling access to artifacts within categories

which is the core of the correct answer.
