Query: Discrepancies

After reading other Network+ books, I found this one to have many errors. I thought it's test questions at the end of the chapters looked like they were going to be better training material. Big mistake. One answer tells you one thing and the very next answer contradicts what the previous one just stated. I also read Ron Gilster's Network+ for Dummies so you would think the material would contain the same information. The Dummies book tells you a Brouter is found in the Data Link and Network Layer, while this book says it's on the Physical and Data Link layer. Inconstistent information and it's definitely not worth the money I paid. This book will be returned.
