CCNA exploration course booklet.

Great book for travel or if you do not have internet. It is word for word exactly on the web version.

This book is word for word the same as the online version. Even references the figures same as the online version, but this book doesn't include any of those pictures it refers you back to the online version for them.

I purchased this to supplement a Cisco class I was taking. It's a thin paperback that fits well in a bag, but I have used it exactly once.
