Question 8: Does Cloudera ask, which particular tool to be used for solving given problem scenario?

Answer: No, Cloudera does not ask to use specific tool for their CDH eco-system, it is your choice in whatever tool you are comfortable, and you should that tool. For example both Hive and Impala are available to work with the data stored in HDFS and it is your choice to use either Impala or Hive. However, Cloudera more interested in that your final and intermediate result should match exactly as per expectations asked in problem scenario.

So now the question is how to prepare for such a scenario so you would be very comfortable for giving your real exam. For that you can use regularly updated certification preparation material and trainings.
