Refer to the exhibit.

The command set workspace-mode normal enables Workspace (ALL ADOMs). The study guide states that in this mode “All ADOMs can be locked” and workspace mode lets administrators lock ADOMs, devices, policy packages, and objects. The lab guide then gives the exact behavior for ungraceful session closure: “If a session is not closed gracefully … FortiManager does not close the administrator session until it times out or the session is deleted. Until this time, the ADOM remains in a locked state.” That directly proves A.

C is also verified by the lab guide statement: “If an administrator locked one or more ADOMs, and then logs out of FortiManager, all of those ADOMs are unlocked.” The phrase “one or more ADOMs” confirms the same administrator can lock multiple ADOMs at once.

D is a workflow mode approval concept, not workspace normal.
