No doubt it is the best ccna dumps there is. But there are a few mistakes in the answers. The question 7 there is an irrelevent answer at the end of the options. I hope those are the only mistakes.

I'm sure this dumps is valid. I check the reviews on the internet and finally choose their site. The dumps proved I made my decision correctly. I passed my exam and got a pretty nice result. I prepare for the 200-310 exam with the latest 400+Qs version. First, I spend about one week in reading the dumps. Then I check some questions on the net. This is enough for you if you just want to pass the exam. Register in a relevant course if you have enough time. Good luck!
