has now newer version of Spark 3.x Certification
in which they would be testing your concepts, underline Spark
Engine Knowledge, How Spark works, What is Catalyst optimizer and
how it works, and extensively on DataFrame API and Some part of
Spark SQL functions. See FAQ at the end of the page and Syllabus
for more detail. And for that in the same 2 Hrs. exam they are

HadoopExam is delighted to announce the availabilty of certification preparation material for this new exam as well. All questions and answers are based on the completely new syllabus, currently we are providing 230+ multiple choice questions and few of the fill in the blanks questions to test DataFrame API extensively. In this Exam your knowledge would be tested for the Spark 3.x using Python. Since last 8 years in the BigData world, one of the fastest growing technology is Spark for sure. Every BigData solution provider has to adopt Spark technology on their platform whether its Cloudera, Hortonworks, HP-MapR, Azure Cloud, IBM etc. All these companies knows the power of Spark and the way Spark had changed the BigData, Analytics and Data Science industry. At the same time Spark itself had changed a lot to make itself gold standard BigData technology and one big driver behind that is Databricks. There are mainly two topics which would be tested for this certification and these are below.
of Spark Architecture and Adaptive Query Execution Framework
Be able to apply the Spark DataFrame API to complete individual data manipulation task, including:
Selecting, renaming and manipulating columns
Filtering, dropping, sorting, and aggregating rows
Joining, reading, writing and partitioning DataFrames
Working with UDFs and Spark SQL functions
|During the exam you
will be given input and expected output and you
need to select the correct code segment which can
produce the output result. Even you would be given
sample data and need to find the min, max, avg,
rename column, add new column in the final output.
Another possible couple of questions would be on
Join. Hence, you must be aware about all kind of
joins like left, right, outer, inner, semi, anti
joins. There would be many questions in which you
would be asked to find the correct code segment
for achieving desired result.
|No, keep in mind in this new certification exam Databricks is not asking any question based on the RDD. Hence, you can safely ignore the RDD API while preparing for this certification exam.|
|You would find 3-4
questions around Spark Architecture. Specially
prepare for the Adaptive Query Execution
framework. You will certainly have questions
around that. HadoopExam certification simulator
has around 25+ questions based on AQE framework.

questions you would find in practice questions.

It is not expected from you to have extensive
knowledge of Scala or Python programming knowledge.
But you must have basic understanding of the either
programming language. If you want to learn Python or
Scala. You can consider the below trainings provided
There would be in total 60 questions given which
would be MCQ (Multiple Choice Questions). You would
be given 120 minutes to solve the same.
You need to score 70% which is equivalent to the 42
questions. So, each question has equal weightage.
No, this is not an open book exam. But to help you
with the API. You would be provided PDF version of
Apache Spark Documentation. Which we don’t think
highly useful. Because if you go through
documentation then it would be good amount of time
wastage. And should be avoided and must be used only
during question review which are tough to answer.
But this is not open book exam and you would not be
able to search answer on the Google.
Below material would be provided during the real
exam would be graded immediately and receive a score
report immediately. And within a week you would be
receiving your certificate in digital format.

No, you need to complete all 60 Questions in 120
minutes. HadoopExam recommends that you spend less
amount of time on Architecture section as there you
don’t have to solve the problem and just your
concepts would be tested. So, all architecture based
16/17 questions should not take more than 15
minutes. But DataFrame API based questions are
complex and matter a lot for passing your exam. And
you need to spend more time on that.
this exam is testing Open Source Apache Spark and no
questions would be asked based on the Databricks
in this exam you would be choosing either Scala or
Python programming language. And language specific
