Exam Question Format
Each CCA175 certification exam dumps pdf 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. This template is written in either Scala or Python.
You are not required to use the template and may solve the scenario using a language you prefer. Be aware, however, that coding every problem from scratch may take more time than is allocated for the exam.
Evaluation, Score Reporting, and Certificate
Your exam is graded immediately upon submission and you are e-mailed a score report the same day as your CCA175 certification guide exam. Your score report displays the problem number for each problem you attempted and a grade on that problem. If you fail a problem, the score report includes the criteria you failed (e.g., “Records contain incorrect data” or “Incorrect file format”). We do not report more information in order to protect the exam content. Read more about reviewing exam content on the FAQ.
If you pass the exam, you receive a second e-mail within a few days of your exam with your digital certificate as a PDF, your license number, a CCA175 exam experience update, and a link to download your CCA175 study guide logos for use in your personal business collateral and social media profiles
Audience and Prerequisites
There are no prerequisites required to take any Cloudera certification exam. The CCA Spark and Hadoop Developer exam (CCA175 books) follows the same objectives as Cloudera Developer Training for Spark and Hadoop and the training course is an excellent preparation for the exam.

Required Skills
Data Ingest
- The skills to transfer data between external systems and your cluster. This includes the following:
- Import data from a MySQL database into HDFS using Sqoop
- Export data to a MySQL database from HDFS using Sqoop
- Change the delimiter and file format of data during import using Sqoop
- Ingest real-time and near-real-time streaming data into HDFS
- Process streaming data as it is loaded onto the cluster
- Load data into and out of HDFS using the Hadoop File System commands
Transform, Stage, and Store
Convert a set of data values in a given format stored in HDFS into new data values or a new data format and write them into HDFS.
- Load RDD data from HDFS for use in Spark applications
- Write the results from an RDD back into HDFS using Spark
- Read and write files in a variety of file formats
- Perform standard extract, transform, load (ETL) processes on data
Data Analysis
Use Spark SQL to interact with the metastore programmatically in your applications. Generate reports by using queries against loaded data.
- Use metastore tables as an input source or an output sink for Spark applications
- Understand the fundamentals of querying datasets in Spark
- Filter data using Spark
- Write queries that calculate aggregate statistics
- Join disparate datasets using Spark
- Produce ranked or sorted data
Configuration
This is a practical CCA175 exam dumps and the candidate should be familiar with all aspects of generating a result, not just writing code.
- Supply command-line options to change your application configuration, such as increasing available memory
