Question #1

You have a 20 node Hadoop cluster, with 18 slave nodes and 2 master nodes running HDFS High Availability (HA). You want to minimize the chance of data loss in you cluster. What should you do?

A. Run a Secondary NameNode on a different master from the NameNode in order to load provide automatic recovery from a NameNode failure

B. Set an HDFS replication factor that provides data redundancy, protecting against failure

C. Configure the cluster's disk drives with an appropriate fault tolerant RAID level

D. Run the ResourceManager on a different master from the NameNode in the order to load share HDFS metadata processing

E. Add another master node to increase the number of nodes running the JournalNode which increases the number of machines available to HA to create a quorum

Question #2

Assuming a cluster running HDFS, MapReduce version 2 (MRv2) on YARN with all settings at their default, what do you need to do when adding a new slave node to a cluster?

A. Add a new entry to /etc/nodes on the NameNode host.

B. Increase the value of dfs.number.of.needs in hdfs-site.xml

C. Restart the NameNode daemon.

D. Nothing, other than ensuring that DNS (or /etc/hosts files on all machines) contains am entry for the new node.

E. Restart the NameNode and ResourceManager deamons and resubmit any running jobs

You are planning a Hadoop cluster and considering implementing 10 Gigabit Ethernet as the network fabric. Which workloads benefit the most from a faster network fabric?

A. When your workload generates a large amount of output data, significantly larger than amount of intermediate data

B. When workload consumers a large amount of input data, relative to the entire capacity of HDFS

D. When your workload consists of processor-intensive tasks

Question #4

You decide to create a cluster which runs HDFS in High Availability mode with automatic failover, using Quorum-based Storage. What is the purpose of ZooKeeper in such a configuration?

A. Clients connect to ZoneKeeper to determine which NameNode is Active

B. It monitors an NFS mount point and reports if the mount point disappears

C. It both keeps track of which NameNode is Active at any given time, and manages the Edits file, which is a log of changes to the HDFS filesystem

D. It manages the Edits file, which is a log changes to the HDFS filesystem.

E. It only keeps track of which NameNode is Active at any given time
