what subnet calculation to use for 70-216?

Cisco and Microsoft do not use the same formula to calculate the number
of possible subnets:

Microsoft: Number of subnets: 2^number-of-subnet-bits

Cisco: Number of subnets: 2^number-of-subnet-bits - 2

http://support.microsoft.com/default.aspx?scid=KB;en-us;q164015
supports this claim but the study guides do not. Not sure which one to
use for the exam

Any help would be appreciated

because the exam is a MS exam you must follow MS guidelines.

Hi,
you should look at the question carefully before answering.

Microsoft: Number of subnets: 2^number-of-subnet-bits
This is the number of subnets that are created.

Cisco: Number of subnets: 2^number-of-subnet-bits - 2
This is the number of subnets you can use to connect devices.

So it depends on what is asked..
