Hello Roberto
We’re glad that you find NetworkLessons useful, and we’ll do our best to help you in your certification journey.
Officially, Cisco frowns upon the use of exam dumps, that is, those that publish real questions from real Cisco certification exams. Cisco consideres this cheating. Therefore we too, here at NetworkLessons do not condone the use of brain dumps. Here is some info about how Cisco views these dumps:
However, it can be very useful to take practice exams that will simulate, as close as possible, the certification experience. Practice exams, which don’t use exact copies of the questions in the real exams, should be a part of your study process.
Take a look at this practice exam that we have put together here:
Each course on the site has a practice exam at the end, so you can test out your skills.
I hope this has been helpful!
