I remembered that the NDIS and ODI question. The NDIS is a standard developed by Microsoft which includes NWLink - Microsoft's implemented driver for Novell Networks. The ODI standard is developed by Apple and Novell. The purpose of both NDIS and ODI is to support multiple protocols on a single network adapter card. There is a 50-ohm terminator on each end of each trunk segment for a total of six terminators.
Answer is three.
You'll notice that each trunk has two terminator and each trunk must be grounded at one end of each trunk to prevent ground loops. That means that if you have four trunks of 10Base5, you need to ground four terminators from each trunk. That's all I remember for now. See the braindump if the site I just gave to you publishes it. I'm a bit disappointed with the score, but I passed the exam and that's what counts.
