Re: Interview question

I agree. I think the way the question was asked with the added detail of the "hung switch" would be consfusing even to someone who is a route/switch guru.

If the interviewer was looking for a Portfast BPDU-Guard answer, this was not the best way to pose the question.

Re: Interview question

It sounds like the interviewer was looking for an answer about the spanning tree protection feature PortFast BPDU-Guard.

Re: Interview question

What was his answer? Not saying I’m a switch guru but if the switch is not responding or “hung” how else would you get it to respond without rebooting?

Re: Interview question

Hello,

what about disabling the port on the other switch thus breaking the loop, getting switch responsive again and then BPDU guard?

Again I agree, that there are better ways of asking for the feature (if it was the intention).

Hope this helps! Pllease rate all posts.
