    I have my CCNA and i am doing N+ to pad out my cv and i like the fact its cert for life if i pass by the end of the year. I am reading Mike Myers ALL IN ONE N+ book and i found some conflicting information on subnetting. Mike is saying you can not use the first of last subnet, Cisco however would say they are usable. I know it used to be the case that the first and last subnets were unsable with Cisco but is now changed. I have used the first and last subnets so i know it can work. So in the N+ exam how should i answer a question ie are the first and last subnets usable or not?

    I have yet to encounter a scenario (from CompTIA or Cisco) where you would be forced to blindly choose one way versus another. Based on the choices provided, you should be able to figure out which way you should answer - meaning, you won't be forced to choose between a "first/last subnet" answer and an "in-between subnet" answer.

    Cheers, I did not want to be in the exam thinking should i make 4 subnets to get 2 usable., when i know i could just creat 2 that would work fine.

    Mike's answer is a good one. I just the N+ this month and I remember very little that actually required subnetting and certainly nothing as sneaky as having to make the can I use the first and last or not.
