Seems fairly straightforward to me. It'll break path MTU discovery. I would hope someone applying for an "IP expert" position would know that. Could HR be mangling the question or something?

I've gotten some "unexpected" answers, so I want to do a sanity check and make sure I'm not asking something unreasonable. And by "unexpected" I don't mean naively incorrect answers, I mean oh-my-God-how-did-you-get-that-cisco-certification answers. The question was: You implement a firewall on which you block all ICMP packets. What part of the TCP protocol (not IP in general, TCP specifically) malfunctions as a result? My questions for you are: 1. As an expert who follows NANOG, do you know the answer? Or is this question too hard? 2. Is the question too vague? Is there a clearer way to word it? 3. Is there a better screening question I could pass to HR to ask and check the candidate's response against the supplied answer? Thanks, Bill Herrin -- William D.

You would be surprised by some of the people I get off the street applying for senior network engineering positions who couldn't connect up a SOHO router and a dumb switch and make them work, let alone understand how PMTU discovery works. -- --- James M Keller
