Question 6

A company has to design a new data system. They will need to support several OLTP applications. Every three days a batch job will run to load specific data into a set of 10 large tables (with historical data) where OLAP analytics will be performed. Performance for both OLTP and OLAP queries is important. Which of the following designs would you suggest to the company?

AUse a NoSQL data store such as MongoDB or Cloudant on the cloud to provide needed scalability

BUse DB2 Data Partition Feature (DPF), partitioning all tables into different partitions

CUse DB2 Data Partition Feature (DPF), only partitioning the 10 tables where Analytics will be run

DUse DB2 with BLU Acceleration, use columnar store for the 10 tables where Analytics will be run

Answer : D

Question 7

Faced with a wide area network implementation, you have a need for asynchronous remote updates. Which one of the following would best address this use case?

AGPFS Active File Management allows data access and modifications even when remote storage cluster is unavailable

BHDFS Cluster rebalancing is compatible with data rebalancing schemes. A scheme might automatically move data from one DataNode to another if the free space on a DataNode falls below a certain threshold

CGPFS File clones can be created from a regular file or a file in a snapshot using the mmclone command

DHDFS NameNode The NameNode keeps an image of the entire file system namespace and file Blockmap in memory. This key metadata item is designed to be compact, such that a NameNode with 4 GB of RAM is plenty to support a huge number of files and directories
