Which component should you use to consume data emitted from Kafka?
A. a bolt
B. a Microsoft Azure Service Bus queue
C. a spout
D. Flume

Correct Answer: C
Explanation/Reference:
To perform real-time computation on Storm, we create "topologies." A topology is a graph of a computation, containing a network of nodes called "Spouts" and "Bolts." In a Storm topology, a Spout is the source of data streams and a Bolt holds the business logic for analyzing and processing those streams.
The org.apache.storm.kafka.KafkaSpout component reads data from Kafka.
