CCD-410 Exam FAQ: What to Know Before You Book
The CCD-410 exam, officially titled Cloudera Certified Developer for Apache Hadoop (CCDH), is the qualifying exam for the Cloudera Certified Developer for Apache Hadoop (CCDH) certification, which sits at the Professional / Intermediate level. Earning it shows employers that you have the skills the credential stands for, and it is a solid step forward on a Cloudera career path. It also connects to Cloudera Certified Administrator for Apache Hadoop (CCAH), Cloudera Certified Data Analyst (CCDA), so the effort you put in now keeps paying off as you advance.
The CCD-410 exam gives you 55-60 questions to complete within 90 minutes. Do the math before exam day: divide the total time by the question count to set a steady per-question pace, and flag any item that stalls you so you can return to it after securing the easier points. The most reliable way to build that rhythm is a full timed practice test under the same limit, which is exactly what TestSimulate's test engines are designed for.
The passing score for Cloudera Certified Developer for Apache Hadoop (CCDH) is 70%, and the official registration fee is $295 USD.

Cloudera Certified Developer for Apache Hadoop (CCDH) Sample Questions:
In the reducer, the MapReduce API provides you with an iterator over Writable values. What does calling the next () method return?
- A. It returns a reference to the same Writable object if the next value is the same as the previous value, or a new Writable object otherwise.
- B. It returns a reference to a Writable object. The API leaves unspecified whether this is a reused object or a new object.
- C. It returns a reference to a Writable object from an object pool.
- D. It returns a reference to the same Writable object each time, but populated with different data.
- E. It returns a reference to a different Writable object time.

You are developing a combiner that takes as input Text keys, IntWritable values, and emits Text keys, IntWritable values. Which interface should your class implement?
- A. Mapper <Text, IntWritable, Text, IntWritable>
- B. Combiner <Text, IntWritable, Text, IntWritable>
- C. Combiner <Text, Text, IntWritable, IntWritable>
- D. Reducer <Text, IntWritable, Text, IntWritable>
- E. Reducer <Text, Text, IntWritable, IntWritable>
You have written a Mapper which invokes the following five calls to the OutputColletor.collect method:
output.collect (new Text ("Apple"), new Text ("Red") ) ;
output.collect (new Text ("Banana"), new Text ("Yellow") ) ;
output.collect (new Text ("Apple"), new Text ("Yellow") ) ;
output.collect (new Text ("Cherry"), new Text ("Red") ) ;
output.collect (new Text ("Apple"), new Text ("Green") ) ;
How many times will the Reducer's reduce method be invoked?
- A. 3
- B. 6
- C. 0
- D. 5
- E. 1

You've written a MapReduce job that will process 500 million input records and generated 500 million key-value pairs. The data is not uniformly distributed. Your MapReduce job will create a significant amount of intermediate data that it needs to transfer between mappers and reduces which is a potential bottleneck. A custom implementation of which interface is most likely to reduce the amount of intermediate data transferred across the network?
- A. Writable
- B. OutputFormat
- C. InputFormat
- D. Partitioner
- E. Combiner
- F. WritableComparable
Explanation: Only visible for TestSimulate members. You can sign-up / login (it's free).
Analyze each scenario below and indentify which best describes the behavior of the default partitioner?
- A. The default partitioner computes the hash of the key and divides that valule modulo the number of reducers. The result determines the reducer assigned to process the key-value pair.
- B. The default partitioner implements a round-robin strategy, shuffling the key-value pairs to each reducer in turn. This ensures an event partition of the key space.
- C. The default partitioner computes the hash of the key. Hash values between specific ranges are associated with different buckets, and each bucket is assigned to a specific reducer.
- D. The default partitioner computes the hash of the value and takes the mod of that value with the number of reducers. The result determines the reducer assigned to process the key-value pair.
- E. The default partitioner assigns key-values pairs to reduces based on an internal random number generator.
