2)With an FMC Overlay it is even more of a doddle!
3) In the NG on the one time I did an NDB DME with it not in the box using an ILS based DME I did use Fix on my side and ILS tuned to the PM side for integrity check. Worked and no misleading indications.
May not be a doddle for a cadet starting to fly on a jetliner. I guessed he wanted to present a situation where the ILS indications shouldn't be there for a good reason (training).
