Question

Which of the following is true of Hadoop? Select one:

a. It is designed to store and retrieve data in a manner that does not rigidly enforce the atomicity, consistency, isolation, and durability (ACID) conditions associated with the relational database model.
b. It is an open-source software framework designed for processing large volumes of data by dividing the work into a set of independent tasks.
c. It is a simple but highly useful way to organize structured data into collections of two-dimensional tables called relations.
d. It is a method to analyze multidimensional data from many different perspectives.

Answer 1

Answer: B. It is an open-source software framework designed for processing large volumes of data by dividing the work into a set of independent tasks.

Step-by-step explanation:

The Correct answer is B because Hadoop is an open source processing software whose purpose is to process and store enormous amounts of information. It counts on great computing power and flexibility.

Answer A is incorrect because Hadoop is not an ACID-Compliant system (Atomicity Consistency Isolation Durability); it is instead a BASE System. (Basically Available Soft State Eventually Consistent)

Answers C and D are incorrect because Hadoop is a very complex software and it is not a method for analysing information, it is a Java-based programming framework.
