D. Allow multiple users to share clusters in a predictable, policy-guided manner.

E. Run jobs at periodic times of the day.

F. Reduce job latencies in an environment with multiple jobs of different sizes.

Answer: BDEF Question: 2 You are running a Hadoop cluster with all monitoring facilities properly configured. Which scenario will go undetected?

A. Map or reduce tasks that are stuck in an infinite loop.

B. HDFS is almost full.

Question: 4 What's the relationship between JobTrackers and TaskTrackers?

A. The JobTracker runs on a single master node and accepts MapReduce jobs from clients. A TaskTracker runs on every slave node and is responsible for managing actual map and reduce tasks.

B. Every node in the cluster runs both a JobTracker and a TaskTracker. The JobTrackers manage jobs, and the TaskTrackers are responsible for managing actual map and reduce tasks.

C. The TaskTrackers runs on a single master node and accepts MapReduce jobs from clients. A JobTracker runs on every slave node and is responsible for managing map and reduce tasks.

D. The JobTracker runs on a single master node, but forks a separate instance of itself for every client MapReduce job. A TaskTracker runs on every slave node and is responsible for managing actual map and reduce tasks.

Answer: B Question: 5 Assuming a large, properly configured multi-rack Hadoop duster, which scenario should not result in loss of HDFS data?

A. Ten percent of DataNodes simultaneously fail.

B. All DataNodes simultaneously fail.

C. An entire rack fails.

D. Multiple racks simultaneously fail.

E. Seventy percent of DataNodes simultaneously fail.
