Overall CCA 175 Certification exam is easy, but you need a lot of practice to complete on time and for accurate answers to the problem. So, enroll for an online course that provides study materials, tutorials from industry experts, and hands-on projects for CCA175 to get yourself prepared in a month. If you are new, you may take one month and if you are familiar with the Spark and Hadoop then 2-3 weeks are good enough.
If you are preparing for the CCA 175 Certification exam, I recommend this Big Data Online Course by Intellipaat.
