What is Hadoop?

• A.Hadoop is programming language capable of transforming raw, unstructured data into plain, regular data readable by traditional data warehouses.
• B.Hadoop is a single-node file system used as a base for storing traditional formatted data.
• C.Hadoop is a framework that allows for the distributed processing of large data sets across clusters of computers using a simple programming model.
• D.Hadoop is a universal Big Data programming language used to query large datasets.

Which of the following options is CORRECT in regards to integrating InfoSphere BigInsights and warehousing environments?

• A.InfoSphere BigInsights Enterprise Edition also comes with a standard Java Database Connectivity (JDBC) connector, making it possible for organizations to quickly integrate with a wide variety of data and information systems, including Oracle, Microsoft SQL Server, MySQL and Teradata.
• B.There is no direct interaction between InfoSphere BigInsighs and data warehousing environments. However, InfoSphere Streams can be used to stream data between the two environments.
• C.Frequently accessed data should be maintained in the BigInsights environment while old?or outdated information can be offloaded to the Frequently accessed data should be maintained in the BigInsights environment while ?old?or outdated information can be offloaded to the warehouse environment.
• D.There is no integration between InfoSphere BigInsights and warehousing environments since they deal with different type of data.

How do big data solutions interact with the existing enterprise infrastructure?

• A.Big data solutions must substitute the existing enterprise infrastructure; therefore there is no interaction between them.
• B.Big data solutions are only plug-ins and additions to existing data warehouses, and therefore cannot work with any other enterprise infrastructure.
• C.Big data solutions must be isolated into a separate virtualized environment optimized for sequential workloads, so that it does not interact with existing infrastructure.
• D.Big data solutions works in parallel and together with the existing enterprise infrastructure, where pre-existing connectors are used to integrate big data technologies together with other enterprise solutions.

Which of the following options DOES NOT describe an advantage of InfoSphere BigInsights on top of regular standalone Hadoop distributions?

• A.Support to HiveQL and PigLatin languages.
• B.BigSheets
• C.Adaptive MapReduce
• D.Integrated install

Which of the following options best describes the differences between a traditional data warehouse environment and a Hadoop environment?

• A.Hadoop environments are mostly ideal for analyzing structured and semi-structured data from a single system, while traditional data warehousing environment is well suited to deal with unstructured data, as well as when a data discovery process is needed.
• B.Typically, data stored in data warehousing environments is rarely filtered and pre-processed. On the other hand, data injected into Hadoop environments is always pre-processed and filtered.
• C.Traditional data warehousing environments are mostly ideal for analyzing structured data from various systems, while a Hadoop environment is well suited to deal with structured, semi-structured, and unstructured data, as well as when a data discovery process is needed.
• D.Typically, data stored in Hadoop environments is cleaned up before storing in the distributed file-system.
