FortiManager global policies and objects are shared across ADOMs, but they are not applied automatically to every package. The study guide states that when you create a global policy package, you can choose the ADOMs you want to apply it to, and you can even pick specific policy packages in individual ADOMs. That directly validates B.

A is also correct because the lab guide explicitly says you can promote ADOM objects to global objects by right-clicking an ADOM object and selecting Promote to Global.

C is incorrect because when Automatically Install Policies to ADOM Devices is enabled, FortiManager installs without giving you a preview/accept step first; the lab warns to use it only when you are sure of the changes.

D is incorrect because FortiManager imports device policies into an ADOM policy package, not into the global package for synchronization.
