CCA-131: Need more sample scenarios or videos to practise

Piks — Sat, 12 Aug 2017 05:46:43 GMT

Hi All, Could you please share some scenarios or sample questions/video series with answer that can help to practice before writing exam? So far very few scenarios or use cases are coming to mind. Looking at the cost of test, we need to be very thorough before going for it.

Have you viewed the video and read through the required skills on the CCA-131 certification page?

@Piks I think we may be having a perception issue but lets walk through this and see for sure. When looking over the certification page, the question format is explained:

Exam Question Format

Each CCA question requires you to solve a particular scenario. Some of the tasks require making configuration and service changes via Cloudera Manager, while others demand knowledge of command line Hadoop utilities and basic competence with the Linux environment.

Looking further down the page, the required skills (see below) should be interpreted as potential questions on the exam. So for instance the first item listed Set up a local CDH repository signifies that you will need to be able show proficiency in setting up a local CDH repository. By looking at the required skills list in this manner, there should be sufficient information available to prepare for the exam. The video with the one example is simply to provide greater context for how the questions will be asked and answered. You should be able to take it from there.

Is there something particular you are looking for in terms of guidance over and above this?
