C. Packets are created when the network layer encapsulates a frame with source and
destination host addresses and protocol-related control information.
D. Packets are created when the network layer adds Layer 3 addresses and control
information to a segment.

Refer to the exhibit. If number 2 is selected from the setup script, what happens when the user
runs setup from a privileged prompt?
A. Setup is additive and any changes will be added to the config script.
B. Setup effectively starts the configuration over as if the router was booted for the first time.
C. Setup will not run if an enable secret password exists on the router.
D. Setup will not run, because it is only viable when no configuration exists on the router.
