Answer : C

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

  • A. Big data solutions must substitute for the existing enterprise infrastructure; therefore there is no interaction between them.
  • B. Big data solutions are placed on top of the existing enterprise infrastructure, acting as a transparentlayer converting unstructured raw data into structured, readable data, and storing the final results in a traditional data warehouse.
  • C. Big data solutions must be isolated into a separate virtualized environment optimized for sequential workloads, so that it doesn?t interact with existing infrastructure.
  • D. Big data solutions works in parallel with the existing enterprise infrastructure leveraging all the unstructured raw data that cannot be processed and stored in a traditional data warehouse solutions.


Answer : D

Answer : D

What is HADOOP?

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