Still can you specify which section; we need to prepare specifically for multiple choice questions?

CRT020 Spark Scala Certification CRT020 : PySpark Databricks Certification Hortonworks HDPSCD2019 Spark Scala Certification Exam Spark Professional Training Spark SQL Hands Training  PySpark : HandsOn Professional Training PySpark Structured Streaming Read Spark SQL Fundamental and Cookbook Spark Interview Questions Cloudera CCA175 Hadoop and Spark Developer Certifications

Answer: Ok, for that you should consider the following sections

-          What is the use of Spark Driver component?

-          What is the relation between core and executor?

-          How executor and tasks are related

-          What do you mean by partitioning and how Spark parallel processing affected by partitioning?

-          Understand these three components working in detail

  1. Jobs
  2. Stages
  3. Tasks

-          And how all these are related to each other.

-          What is the caching, and how it can be implemented?

-          You would certainly get multiple choice question based on caching and memory management.

-          Understand the Spark architecture

-          Make yourself well aware about wide and narrow transformation (discussed in this book in depth)
