Actually, this is _exactly_ the kind of questions I would be afraid
of. Why? Because I recently passed my CCIE RS exam, and yet I don't know
the default timers Cisco uses for various protocols on various interface
types.
Why is that? Because I do not need that information in order to
_configure_ and _troubleshoot_ that protocol (which should be the
primary objective of the CCIE lab exam). I know that those timers exist.
I know that for some protocols mismatching timers can lead to neighbors
not establishing an adjacency. Therefore, I know that when my neighbors
do not come up, one of the things I need to check is the value of the
timers on both ends.
However, I really don't see a situation in which I need to know that
"Cisco uses a default hello interval of 10 seconds for OSPF on broadcast
links". Even if I am required not to change the hello time on one end of
the link, I can still go to that router, do a "sh ip ospf int", and see
the current value.
