Interview questions for network engineers

A few months back I came across a site that listed the skills and courses that Google considers important on the road to becoming a software engineer - Google Careers Guide For Technical Development.  This morning I stumbled across it again as I was cleaning out my bookmarks (I really don't need to save that link to Chelsea Manning trying to justify her decision to dump a billion documents to Wikileaks) and thought I would do a quick search to see if anyone had put together anything similar for network engineers.

Alas no.  At least not that I found in my 30 seconds of furious googling, but I did find a site called Router-Freak which has a quite a few interesting articles, among them - Interview Questions for Network Engineers:

(I didn't want to steal all their work so I commented most of the questions out.  They didn't do that to get you to pay or something.  It's all me)

It's no 7 of 9 Lectures on OSPF ( +Jeri Ryan  is eventually going to get tired of these references and sue us all, but you can work them into everything.) or Britney Spears Guide to Semiconductor Physics but I find the site sufficiently worthy to be included in my RSS feeds.
