Cloudera Certified Administrator for Apache Hadoop CDH4 Upgrade Exam (CCAH) Sample Questions:
Question 1
What determines the number of Reduces that run a given MapReduce job on a cluster running MapReduce v1 (MRv1)?
A. It is set by the developer.
B. It is set by the JobTracker based on the amount of intermediate data.
C. It is set and fixed by the cluster administrator in mapred-site.xml. The number set always run for any submitted job.
D. It is set by the Hadoop framework and is based on the number of InputSplits of the job.
Question 2
For a MapReduce job, on a cluster running MapReduce v1 (MRv1), what's the relationship between tasks and task templates?
A. There are always at most as many tasks attempts as there are tasks.
B. There are always exactly as many task attempts as there are tasks.
C. The developer sets the number of task attempts on job submission.
D. There are always at least as many task attempts as there are tasks.
Question 3
You have cluster running with the FIFO Scheduler enabled. You submit a large job A to the cluster, which you expect to run for one hour. Then, you submit job B to cluster, which you expect to run a couple of minutes only.
You submit both jobs with the same priority.
Which two best describes how the FIFO Scheduler arbitrates the cluster resources for a job and its tasks?
A. Tasks are scheduled in the order of their jobs' submission.
B. The order of execution of tasks within a job may vary.
C. Because there is more then a single job on the cluster, the FIFO Scheduler will enforce a limit on the percentage of resources allocated to a particular job at any given time.
D. The FIFO Schedule will pass an exception back to the client when Job B is submitted, since all slots on the cluster are in use.
E. The FIFO Scheduler will give, on average, equal share of the cluster resources over the job lifecycle.
F. Given Jobs A and B submitted in that order, all tasks from job A are guaranteed to finish before all tasks from job B.
Question 4

A. Write data to two clusterssimultaneously
B. Automatically 'fail over' between NameNodes if one goes down
C. Manually 'fail over' between NameNodes
D. Configure unlimited hot standby NameNode.
E. Shut one NameNode down for maintenance without halting the cluster
Question 5
Identify two features/issues that MapReduce v2 (MRv2/YARN) is designed to address:
A. Single point of failure in the NameNode.
B. Standardize on a single MapReduce API.
C. HDFS latency.
D. Reduce complexity of the MapReduce APIs.
E. Ability to run frameworks other than MapReduce, such as MPI.
