1. 1Which two components make up a FlowFile in Apache NiFi?

   1. A.Content and a processing relationship
   2. B.Filename and a connection queue
   3. C.Content and its attributesCorrect answer: C
   4. D.Attributes and a connection queue

   Explanation: The guide states: "A FlowFile is made up of two components: FlowFile Attributes and FlowFile Content." The filename is an attribute, while relationships and connection queues are separate flow components.

2. 2What role does a Kafka broker perform in a cluster?

   1. A.Store topic records and serve consumer requestsCorrect answer: A
   2. B.Publish application records as a producer client
   3. C.Subscribe to topics as a consumer application
   4. D.Provide an external-system connector as a Connect worker

   Explanation: Cloudera states: "A broker is a server that stores messages sent to the topics and serves consumer requests." Producers, consumers and connectors perform different roles.

3. 3In Cloudera Data Flow's two-tier architecture, where are the Catalog and data-processing deployments hosted?

   1. A.Catalog on the Control Plane; deployments in the cloud provider accountCorrect answer: A
   2. B.Catalog in the cloud provider account; deployments on the Control Plane
   3. C.Both Catalog and deployments on the Control Plane
   4. D.Both Catalog and deployments in the cloud provider account

   Explanation: Cloudera describes the placement: "Cloudera Data Flow follows a two-tier architecture where product capabilities like the Overview, Catalog and Environment management are hosted on the Cloudera Control Plane while the deployments running the flows that process your data are provisioned in a Cloudera environment which represents infrastructure in your cloud provider account."

4. 4What role does a MiNiFi agent serve in Cloudera Edge Management?

   1. A.Execute data collection and processing at an edge deviceCorrect answer: A
   2. B.Provide the central hub for managing many edge agents
   3. C.Provide the central interface for deploying flows to agent classes
   4. D.Monitor all edge agents from the management server

   Explanation: Cloudera states: "MiNiFi - A lightweight edge agent that implements the core features of Apache NiFi, focusing on data collection and processing at the edge." This supports the selected answer.

5. 5Which standard FlowFile attribute distinguishes one NiFi FlowFile from others in the system?

   1. A.path
   2. B.filename
   3. C.priority
   4. D.uuidCorrect answer: D

   Explanation: The guide defines "uuid: A Universally Unique Identifier that distinguishes the FlowFile from other FlowFiles in the system." Filename and path describe storage-related information; priority can be used to order queued FlowFiles.

6. 6What happens to a Kafka event merely because a consumer has read it?

   1. A.It remains available subject to the topic's retention settingsCorrect answer: A
   2. B.It is removed from the partition after the first consumer reads it
   3. C.It is removed only after every consumer group has read it
   4. D.It is retained only until the first consumer commits its offset

   Explanation: The introduction states: "Events in a topic can be read as often as needed-unlike traditional messaging systems, events are not deleted after consumption. Instead, you define for how long Kafka should retain your events through a per-topic configuration setting, after which old events will be discarded." Reading an event alone does not delete it.

7. 7How do Data Flow deployments interact with the Control Plane during data processing?

   1. A.Send health and performance heartbeats to the Control PlaneCorrect answer: A
   2. B.Send all FlowFile content to the Control Plane for processing
   3. C.Execute NiFi flow logic within the Control Plane
   4. D.Receive the processed FlowFile content from the Control Plane

   Explanation: Cloudera states: "Flows and deployments send heartbeats containing health and performance information to the Control Plane where this data is visualized and presented in the Deployments view." Flow logic runs in the cloud account and processed data does not traverse the Control Plane.

8. 8Compared with the MiNiFi Java agent, what tradeoff does the C++ agent offer?

   1. A.A smaller footprint with a more limited subset of NiFi processorsCorrect answer: A
   2. B.A larger footprint with a more limited subset of NiFi processors
   3. C.A smaller footprint with broader NiFi processor support
   4. D.A larger footprint with broader NiFi processor support

   Explanation: Cloudera states: "The Java agent is able to run most of the available processors of NiFi, but is a larger binary distribution and consumes greater system resources." It also states: "The C++ agent is a smaller binary, consumes low system memory but it is able to run a limited subset of NiFi processors."

9. 9What does the name of a NiFi processor relationship indicate?

   1. A.The result of processing a FlowFileCorrect answer: A
   2. B.The input format accepted by the processor
   3. C.The physical location of the connection queue
   4. D.The interval at which the processor is scheduled

   Explanation: The guide says: "These Relationships are named to indicate the result of processing a FlowFile." The relationship can be connected to route that processing result.

10. 10At what level does Kafka replicate the data of a topic?

    1. A.Each topic-partitionCorrect answer: A
    2. B.The entire topic as a single indivisible log
    3. C.Each producer session independently
    4. D.Each consumer group's assigned offset

    Explanation: The Kafka introduction states: "This replication is performed at the level of topic-partitions." This supports the selected answer.
