I have people waive the "I'm Cisco Certified" flag in my face all the time. 
Then proceed to ask me if we have a T1. To the point that it's no longer a 
valuable achievement in my eyes.

I'm certified to perform CPR in the state of Florida... I should go apply 
for a surgeon position at the local hospital.

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?

Hi folks,

I gave my HR folks a screening question to ask candidates for an IP
expert position. 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

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.
