(CCA175) 90%

Today i have cleared CCA175 and Scored 9 out of 10 questions..... I have gone through all the CCA175 Questions and practice the code provided by HadoopExam.com Thanks for your questions and code content. The content was excellent and it helped me a lot.
(Especially I have gone through all the Spark Professional training module as well, i missed your Spark SQL training because it was launched late. But i wish to subscribe this training as well for my further learning). My feedback about real exam, i got 2 questions in Sqoop, 7 questions on Core Spark, file formats, Spark SQL (fantastic scenarios in simulator), and 1 questions on HDFS commands. Your 111 questions is good for somebody to save time as well as very organized learning. Now i am looking for more advanced certification CCP:DE575

Thanks you sooo.. much
