CCNA ICND2 Official Exam Certification Guide 5 out of 5 based on 0 ratings. 1 reviews.
Chad96 More than 1 year ago
I have used the INCD1 to obtain my CCENT and now using INCD2 to get my CCNA. I found when taking the INCD1 the practice exam on the CD is harder than the actual exam. I am assuming this is the same way for INCD2. I would use this book when trying to get your CCNA because it is made by Cisco Press(the same company that makes the test). There is actually too much information in the book but it is definitly for people who like to truely understand how something works.
