Hi Guys,
Just doing my last minute prep for the 291 (Exam tomorrow at 10:30).
I have a question on maximum number of subnets. Say I get a question in the exam asking for the maximum number of subnets, would the correct answer be the RFC 1812 number ( say /19 = 8 subnets of 8192 ids / 8190 max hosts per sub) or would I need to minus 2 from the maximum (so /19 = 6)?

From my experience it isn't something that you'll run into unless they specifically mention non-compliance or compliance. But if you have to make an assumption I would assume compliance.Jumping on the IT blogging band wagon -- http://www.jefferyland.com/ -

I'd go with the minus 2 answer.

A little late but oh well.
But always do 2n-2 for hosts and 2n for subnets.
