I'd accept those if I was willing to send the candidate to rational IPv6 networking re-education camp. If I expected the candidate to be able to do real work immediately, I would require the correct answer as specified above. Assigning a /56 to an end-site is bad juju. Assigning a /60 is pure useless evil.
5. What is the reason for the 100m distance limit within an ethernet collision domain?What's an ethernet collision domain? Seriously, when was the last time you dealt with a half duplex ethernet?You've never (much less recently) seen a customer misconfigure their end of an ethernet handoff such that you end up with duplex mismatch? Granted, in that case, distance is irrelevant...but it is half half-duplex ethernet :)
Either way, the collision domain itself is irrelevant to the question at hand... The important thing is to find out that the candidate understands what an ethernet pre-amble is and why it is important. Owen
