Hi there! I have a rather important question which I hope someone knowledgeable will be able to help me with.
It's a rather important subnetting question. And I'm asking, how do you find the number of subnets?
Ok at this stage I'd like to point out that I do actually know how to find the number of subnets but I'm rather confused which method is acceptable for the CCNA exam.
In all my literature it is stated that in order to find the number of subnets one must do the follwing calculation:
2 to the power of n, minus 2 (where n is the number of borrowed bits).
However, in an official Cisco video made by Yash Bajpai, and incidentally, one can view it in the CCNA Prep Centre, he mentions in order to calculate the number of subnets one must do the following calculation:
2 to the power of n (where n is the number of borrowed bits).
Whilst I understand that on a Cisco router it is possible to create subnets using Yash Bajpai's method, is it now the correct answer for the exam?
Thank you all in advance for your help.
I look forward to hearing from you.
