Topics to focus on for CCA175


I want to know what are the topics which I need to focus on for CCA175.

In exam, does questions related to flume/kafka/spark streaming, creating app jar and running it, writing hive queries come as part of question? Or just related to spark, sqoop and hive queries integrated with spark come?
I have also heard that generally there are 9 questions out of which 2 are realted to sqoop and remaining are related to core spark/dataframe. Is that correct?

Can someone help me with this.
