For the Cisco CCNA exam there are going to be questions regarding subnets. The formula for calculating subnets is 2^n unless the router IOS shows the command "no ip classless" which makes the formula 2^n-2.
So my question is simple. Which mode is Cisco going to use on their testing? By default a Cisco router does enable "ip classless" and you have to specify "no ip classless" manually. The lastest training I went through also said the Cisco test questions would specify "no ip classless", however on the latest pass4sure testing engine the question assumes "no ip classless" although that is not the router default.
