1) The Developer course maps the the CCA175. The CCP DE575 is a difficult exam meant to test development mastery. A data analyst taking this exam would be very unhappy. DE575 most closely maps to our Big Data Applications course (plus some years of experience).
3) The testing objectives for our certifications are close to the learning objectives for the courses, and the courses have exercises that will help you practice for the practical nature of the exam. The training is not required, however.
4) There is no Java on the exam, but there is development work that needs to be done. See question 2.
I knew C++ as well as I took Hadoop training. After I completed my training, I've been practicing for test almost 7-8 months. Now, I feel like I am ready give a shot but I am still hesitant due to the fact that Cloudera changed CDH 410 to CCA-175. This is the reason why I am looking for CCA 175 exercises.
If you do not wish to take our training or cannot afford it, there are hundreds of free resources on the internet. For example, if I point my browser to the List of objectives from our website. I then copy the first objective and search on it, I get dozens of free docs and training on the skill.
This can be done for any of our exams. Of course the quality of materials freely discovered on the internet differs greatly, as does the discount training vendors, which is why we only recommend Cloudera training.
