Hi Few of my friends did ccna exam last month and passed it but they told me that now dumps cannot be trusted much you get lots of new questions very quickly the dump can be trusted around 70% so when you get around 10 new questions automatically you fail the exam because to pass the exam you must get 82%
so the only trusted way to pass the exam is understand the subject 100% do the labs and after that go through dumps then you can pass the exam
also if you have any doubt or any question on any subject post your question on the forum so I and others here can help you pass the exam
