My question is there are thousands of websites which are pursuing candidates that they have 100% real guaranteed exam questions and dumps like;

If they are true in this regard, these certifications have lost their worth?

There are some folk that can't learn the skills in these topics but can recall questions and answers so for them this is the only way for them to pass these exams.

What happens next is they land a job but can't perform since they are now in the real world. I used to think such sites to be terrible but now think that anyone foolish enough to use such gets what they deserve later.
