Yes, rebooting with option 4, allowed me to move on. If you have access to Simulate_ONTAP_8.1.2.pdf, it would be great to add this step there.
I still can't ping the simulator, probably because of network adapter setup problems on the VM hosting it. It would be helpful to have more detailed instructions for the adaptor setup in the Simulate_ONTAP_8.1.2.pdf too. For example, why DHCP is needed for using the bridged configuration.
