AThe System Orchestrator role
BThe Big Data Framework Provider
CThe Data Provider role
DThe Data Consumer role
Answer & Solution
Correct answer: C. The Data Provider role
1. The summary list is explicit: "Data Provider: Introduces new data or information feeds into the Big Data system."
2. The word feeds matters. A Data Provider is not only a one-off source of a dataset; it can be a continuing stream into the system.
3. The Data Consumer is the mirror image, defined as including "end users or other systems who use the results of the Big Data Application Provider". Data flows in through the Provider and out through the Consumer.
4. The System Orchestrator sets requirements rather than supplying data, though it does specify "Data Provider contracts and service-level agreements (SLAs)" as part of its business ownership duties.
5. The Big Data Framework Provider "establishes a computing framework in which to execute certain transformation applications while protecting the privacy and integrity of data", which is infrastructure rather than input.
