If you’re looking for course materials that you can install for offline viewing, click here to check the CCNA Exploration 4.0 Curriculum / Course Material installers, for offline viewing. They have more explanations that these PPT slides.
Finally, Accessing the WAN! My last CCNA (I really hope that it is already!).
In this page I’m sharing the Powerpoint slides of chapters 1 to 8 for CCNA 4. The .ppt slides (instructors’ materials) are useful if want a quick reading about the chapters or for reviewing before exams.
