CISSP · Question #1238
When determining data and information asset handling, regardless of the specific toolset being used, which of the following is one of the common components of big data?
The correct answer is C. Distributed data collection. Big data is characterized by several defining traits, one of which is that data is collected from many distributed sources rather than a single consolidated point.

Why each option
Big data is characterized by several defining traits, one of which is that data is collected from many distributed sources rather than a single consolidated point.
Consolidated data collection describes a traditional, centralized data aggregation model that is the opposite of big data's distributed collection paradigm.
While distributed storage can be a component of big data infrastructure (e.g., HDFS), it describes where data is stored after collection, not a defining characteristic of big data collection itself, making it less precise than distributed data collection.
Distributed data collection is a foundational characteristic of big data, often described through the 'V' framework (Volume, Velocity, Variety, Veracity). Data originates from numerous geographically and logically separate sources-sensors, social media, transactions, logs-making distribution inherent to how big data is gathered. This distributed nature is what distinguishes big data collection architectures from traditional centralized data warehousing approaches.
Centralized processing is antithetical to big data architectures, which rely on distributed processing frameworks like MapReduce and Apache Spark to handle data at scale across multiple nodes.
