I am teaching CCNA2v7:Switching, Routing, and Wireless Essentials and I noticed that the answers to the Module Quizzes at the end of each chapter are not always correct. Specifically, every time you choose the option "Show Me" you get a different answer as the correct one. This was discovered by one of my students and I actually verified it myself. Do you experience the same problem? It is very annoying and very confusing for the students. We need a solution asap!
