Click for More Detail) Cloudera CCPDE575 (Hadoop BigData Data Engineer Professional Hands-on Certification available with total 79 solved problem scenarios. Click for More Detail) Cloudera CCA159 Data Analyst Certification Practice Questions (Total 73 HandsOn Practice Questions) Question 1: How frequently CCA175 questions or syllabus updates? Answer: Generally, we don’t see any fixed timeline for syllabus updates, CCA175 exam syllabus are certainly revised time to time. We have seen many times (almost every year) in last few years not only syllabus but questions pattern have changed. Cloudera is pioneer for the Hadoop/BigData framework and we have been following it since 2012 to make our CCA175 Certification product in-line with their syllabus. Regarding updates, you need to continuously check for the syllabus on Cloudera certification page. However, 1000’s of learners use our certification preparation material, so we get update frequently and it is easy to update http://www.HadoopExam.com CCA175 certification simulator. Once the Cloudera update the syllabus, you should always prepare according to that new syllabus. Frequency of syllabus update is once in a year, we have seen till now. Question 2: If I found any issue, with scheduling of CCA175 exam, whom should I contact? Answer: You can use the email id provided at their certification page [email protected] . We have seen many learner face problem for scheduling the exam and they need to contact Cloudera for the same. Currently exam is conducted on AWS platform and some unique AWS ID is assigned/used for each certification aspirants. Once an ID is used on AWS, then Cloudera will not be able to register that particular email again. If you face problem than use above email id, this is one of the best way to resolve this issue. Question 3: I am using Scala for my CCA175 certification, but as I know for submitting application in Scala/Java, I need to first create a Jar out of my code. It will take lot of time and I am not sure that tools will be available to create Jar file, during exam? Answer: Hmm, this is very valid question. Learners who use Scala for CCA175 exam, they always face this concern. However, Cloudera is not going to test, that you have knowledge of building jar or not. Hence, you should not worry about building the jar file for your Scala code, instead use spark-shell to submit your Scala code line by line and produce the desired result. Not creating Jar file, will save your lot of time. You need to consider these questions for preparing for CCA175 certification, because more than 50 Spark practice questions are given, in total you will find 111 questions for CCA175 exam these are always updated based on new syllabus. You can run all the example line by line as well, and same practice you need to follow in real exam. If you are using Python instead of Scala, then you don’t have to build a Jar kind of package to submit your application. Go through this 111 updated questions, you will become very well comfortable with the real exam. Make sure, you practice all questions with valid version of Spark framework, otherwise your practice go wasted, you may have learn to run code with the latest API, but that might not work with Cloudera real exam environment. Based on or learners feedback, we have recently updated these questions and added 16 new questions. Our learners average scoring is 9/10 and even many learners scored 10/10. By completing this 111 questions, you will not only able to clear your exam, but you can use same practices in your daily regular routing work for Big Data Engineering using Spark, Scala, Python, Sqoop, Flume, HDFS, Shell Script, Spark SQL and much more. These CCA175 questions are regularly updated based on our learner’s feedback, hence once you appear in exam, please provide feedback about your experience in real exam on [email protected] , and anything new you find regarding the exam, if we are missing this will help all the future aspirants. You will have to save the code, somewhere which you have used in spark-shell, so that Cloudera can verify your approach. They will provide you the detail, where to submit/save the code. Question 4: Which version of Spark is used in CCA175 certification? Answer: Let me first tell you that Cloudera is not only testing your Spark programming skill, they are testing that you are able to work with currently available CDH (Cloudera Distribution of Hadoop) version. Which is bundled with many eco-system of BigData Hadoop, Spark is one of them, and they wanted to test many of the available components for the developer. Even you see most of the organization use Spark well integrated with the Hadoop distribution either HDP, CDH or MapR Hadoop. Hence, whatever Spark version is available in that particular CDH version, will be tested. Hence, currently you should be able to write code using Spark 1.6 programming API. That is why it is very important that you practice questions based on specific version of Spark and the best approach to follow these 111 questions of CCA175, which has detailed problem statement as well as its step by step solution, which has been executed on that specific Spark platform. Not only you should get acquainted with the Spark 1.6 programming model, but also you should become comfortable working with the CDH platform, how to use path for file stored in HDFS , how to use JDBC connection, specially connection MySQL database using Spark 1.6 only (Don’t use older or newer version, be specific here). Question 5: I am quite comfortable using Sqoop and I practiced all the 111 questions of CCA175, given here. But I cannot remember all the options used in Sqoop import and export command, what to do in this case? Answer: Generally programmer don’t remember all the APIs and options of the commands, but they are aware this particular feature is available and to know the exact syntax they need to use documentation. Cloudera provides the documentation for Sqoop in CCA175 real exam. As you are quite comfortable after practicing these 111 questions, you may not need to go to documentation, to save time. Rather go to terminal and type sqoop help import or sqoop help export etc. This would be quite faster approach and save lot of time. This is very important you are well managed during the exam and no all the possible ways of saving your time. But don’t get panic, and calmly follow the documentation if you forgot to use particular command syntax. Cloudera will provide all the documentation for the products used in their CDH platform. Question 6: Cloudera introduce another exam for Data Analyst CCA159, does it make any difference with the existing CCA175 exam? Answer: Cloudera Hadoop Distribution are used by many different profile of professional, like if you are a data analyst then you should not be writing complex programming in Spark, but rather prefer SQL based solution. If you are a developer than you will be using programming to work with data. Even for the people/learners who are more comfortable with the advance feature of Cloudera Hadoop Distribution most of the Big Data architect and experienced developer use CCP:DE575 exam (this is Cloudera Certified Professional exam). So the main impact of introducing Data Analyst exam is that many type of questions, will be moved out of CCA175 exam like DDL (Data Definition Question) defining tables etc. However, we suggest being a developer you should be able to do this. More complex DML syntax are not expected from you in CCA175 exam, like write very complex Hive and Impala queries, this is expected in CCA159 exam instead. You should be able to use Hive meta-store from Spark, Sqoop etc. and able to write some queries using Spark SQL (But very complex queries, specially analytical functions based queries are not expected). You should be able to filter, format, join the data in CCA175 exam. So the best way to be specific preparation use this 111 questions for practicing your real exam. Average scoring by learners is 9/10 after practicing this CCA175, total 111 questions, which come along with the required data as well as solution and also complimentary videos are available in which solution and problem are explained in detail. Whenever syllabus changed, feedback from previous learners are very helpful and we at http://www.HadoopExam.com integrate that feedback as soon as possible after receiving it from the learners. We have launched this CCA175 certification material with just 50 practice questions and now we have in total 111 questions, which are updated and corrected based on feedback of successful candidates. Question 7: What exactly is the CCA175, 111 question pattern and HadoopExam.com problem scenario follow the same pattern? Answer: Each CCA question requires you to solve a particular scenario. In some cases, a tool such as Impala or Hive may be used. In other cases, coding is required. In order to speed up development time of Spark questions, a template is often provided that contains a skeleton of the solution, asking the candidate to fill in the missing lines with functional code.
