You are hosting a Slack training for your client, Elevated Enterprises, who just completed their...

The correct answer is B . After an Enterprise Grid migration, users may belong to different workspaces inside the same grid. A public channel is discoverable only to members who have access to the workspace where that channel exists, unless it is made available as a multi-workspace or org-wide channel. In this scenario, some users can find and join the training channel, while others cannot. That pattern strongly indicates the channel itself is public, but it lives in a workspace that not all attendees belong to. Option A is possible in isolated cases, but it would not explain a consistent split across attendees. Option C is irrelevant because Slack Connect is used for collaboration with external organizations, not internal training-channel discovery. Option D would prevent users from joining through search unless invited, but it would generally affect all attendees who were not invited. The training setup should either invite all participants or place the training channel in a workspace accessible to the full training audience.
