Refer to the exhibits.

The best conclusion is A. From the exhibit, B is clearly incorrect because policy sequence #1 Ping_Access is targeted to ISFW root and ISFW Student, not to root NAT and Trainer NAT. Also, C is incorrect because FortiManager allows a rule to inherit Installation Targets. The study guide explains that a policy package can target one or more devices or VDOMs, and the Install On column is used only for per-rule exceptions in a shared policy package. A rule does not need explicit devices listed if it is meant to apply to the package’s installation targets.

D is also incorrect because global header policies are created in the Global Database ADOM and placed at the top only when a global package is assigned. The exhibit shows a shared policy package, not a global ADOM header-policy assignment.
