How should an administrator enable the Advance Routing Engine on a Palo Alto Networks firewall?

According to PAN-OS documentation, the Advanced Routing Engine is a global firewall setting. It is enabled from Device > Setup > Management > General Settings by checking “Enable Advanced Routing Engine,” followed by a commit and firewall reboot. Only after this global toggle is on can individual virtual-router objects use the new engine. Therefore, option C is the only path that actually turns the feature on.

A. No “Advanced Routing” control exists under Device > Setup > Session; path is irrelevant.

B. Router-level “Forwarding Mode” appears only after the engine is enabled globally; it cannot enable the engine itself.

D. Redistribution Profiles control route-redistribution, not engine selection; path contains no such setting.
