It doesn't matter.
The MIB handler can explicitly return a noSuchInstance or
noSuchObject exception, or simply return without setting a
value at all. The main agent driving code will recognise
this, and move on to the next registered MIB region.

The main agent driving code will move on to the next MIB region.

Correct.
The agent will move on to the next registered region.
If there isn't one, then it will respond with endOfMibView.
