Hello!!! I'm going through some of the questions in the book so I can re-certify myself again... of of the questions I'm having difficulty is:

For the following set of networks, determine the summary address and the mask to be used that will summarize the subnets...
192.168.1.0 through 192.168.120.0

I'm coming up with an answer of /17 (255.255.128.0) but the book I'm working form is giving me an answer of /25 (255.255.255.128)

I'm correct and the book is wrong.... right???

 
I think you are correct just giving it a quick look. What book are you using? If from ciscopress, go check and see if there is an errata for it. I've learned the hard way, there are mistakes in the books, but they have done a good job of correcting them and adding updates to the website.
