Just passed my exam. 4 new questions in my exam. You need to be careful. Do not just learn the answers by heart. Better to get understanding about why the correct answer is this one not that one. Recommend.

Passed my exam this morning. Only dumps I used was this one. The trick is to read it at about 3 hours a day, so you actually retain what you're reading. It also helps to write down the options and correct answers. I'd recommend it to anyone trying to decide on a dumps. Plus, this thing is a monster so you get a good study guide and built in self defense weapon for only such a little amount.
Valid dumps. Answers are accurate. I come get few new questions in the exam. Maybe 2-3 VERY SIMPLE. Good Luck All!!!!
Answers are correct. Questions are valid.Recommend strongly.

took the exams yesterday and passed. I was very scared at first because the labs came in first so I was spending like 10 to 13mins so I started rushing after the first three labs thinking that I will have more labs. I ended up finishing the exam in an hour..d dumps are valid. I tink there is a new lab. good success
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.
