The correct answer is B. The error occurs because the script is being run on the policy package database, but the failing command is config sys interface, which is a device-level configuration command, not a policy-layer command. The lab guide gives the exact relationship: “Because the scripts target the device database, first, you will run the scripts against the device database, and then install the scripts on the managed devices” and “The scripts contain configuration changes related to device-level settings.”

By contrast, the lab guide shows Policy Package or ADOM Database scripts being used for firewall objects and policies in a policy package.

So this NetFlow script must be run on the device database, then installed. The issue is not VDOM permissions, metadata variables, or normalized interfaces.
