The correct answer is A . By default, everyone except guests can send and accept Slack Connect direct message invitations with people outside the organization, unless the Enterprise Grid organization modifies those settings. This distinction matters because Slack Connect DMs are a lower-friction form of external collaboration than shared channels, but they still require governance. Full members are normally allowed to initiate or accept external DMs, while guests are excluded because their membership is already limited and scoped. Option B is too restrictive and describes an admin-only model that is not the default. Option C incorrectly places control with workspace-level admins and owners. Option D is too broad because it includes guests, which conflicts with the default exclusion. The consultant should explain both the default behavior and the client’s ability to tighten policy if the organization’s risk profile requires stricter external collaboration controls. For regulated or security-conscious clients, this setting should be reviewed during the policies and settings workshop.
