Build an IoT Blockchain Network for a Supply Chain

Lab 1: Build a blockchain network

Question 1: The default blockchain Perishable Goods Network in Hyperledger Composer includes which participants? Select all that apply.

  • Grower
  • Exporter
  • Shipper
  • Importer

Question 2: Which of these file types is used for a model file?

  • BNA
  • JS
  • CTO
  • ACL

Question 3: To capture conditions for a crash, a hard jolt, or other incidents based on the accelerometer data, what field did you add to the Contract asset?

  • DateTime arrivalDateTime
  • Double maxAccel
  • AccelReading[] AccelReadings optional
  • ShipmentStatus status

Question 4: What is the purpose of this event: TemperatureThresholdEvent()?

  • To notify participants when agreed on temperature thresholds are exceeded
  • To alert the delivery vehicle driver or owner when temperatures exceed a specific threshold
  • To force the temperature sensor on a delivery vehicle to rest
  • To notify participants that the contract has been breached

Question 5: In a DevOps pipeline, what occurs during the BUILD phase? Select all that apply.

  • Clones your GitHub repository
  • Provisions and configures an instance of the blockchain network
  • Runs all of the automated unit tests for all of your smart contracts
  • Installs any dependencies

Understand the imported Node-RED flows

Question 1: Which task is not done by the Start Particle Electron flow?

  • Sends a command to enable or disable the device geolocation reporting
  • Controls the interval of the report
  • Queries the temperature blockchain transaction history
  • Retrieves accelerometer and current temperature data

Question 2: Which flow takes the arriving data, reformats it, and calls the next flow to write the Particle Electron events to the transaction history of the blockchain network?

  • Track Asset History
  • Load Blockchain
  • Start Particle Electron
  • Particle Receiver

Question 3: Which flow sets up a series of GET and POST commands?

  • Track Asset History
  • Blockchain REST API
  • Load Blockchain
  • Start Particle Electron

Question 4: The Track Asset History flow filters the array to the selected device and time frame.

  • True
  • False

Question 5: What is one task that is done by the Load Blockchain flow?

  • Sends a command to enable or disable the device geolocation reporting
  • Provisions and configures an instance of the blockchain network
  • Queries the temperature blockchain transaction history
  • Constructs a variety of Node-RED dashboard UI elements

Build an IoT Blockchain Network for a Supply Chain Final exam Answers Cognitive Class

Question 1: What is the purpose of exposing the blockchain network as a REST API?

  • To allow appropriate participants in the network to update the blockchain contract
  • To allow other developers to access the blockchain network
  • To allow the network to run on IBM Cloud
  • To manipulate the blockchain from Node-RED

Question 2: What is included in the Internet of Things Platform Starter? Select all that apply.

  • CouchDB database
  • Node-RED Node.js web server
  • Cloudant database
  • IoT platform service

Question 3: What is the purpose of the ParticleSSE node in the Particle Receiver flow?

  • Sends a command to enable or disable the device geolocation reporting
  • Sets up a POST command that writes a temperature event into the blockchain as a transaction
  • Allows you subscribe to incoming server-sent events (SSE) on a Particle cloud through a persistent connection
  • Queries the temperature blockchain transaction history

Question 4: What is the main task of this flow?

  • Queries the temperature blockchain transaction history
  • Create a UI dashboard to track assets
  • Sends a command to enable or disable the device geolocation reporting
  • Connects your Node-RED flow to IBM Cloud

Question 5: Hyperledger Composer REST APIs cannot be used by Node-RED to communicate to the blockchain perishable network.

  • True
  • False

Question 6: What must you add to the model file for the IoT data to be associated with the asset and shipment?

  • IoT variables
  • A field for the accelerometer value
  • Events that alert the appropriate participants when agreed on thresholds are exceeded
  • An updated logic.js file

Question 7: When you export the code for your network from Hyperledger Composer, what type of file is created?

  • BNA
  • JS
  • JSON
  • ZIP or TAR

Question 8: You use the Google Maps Locator API to triangulate the geographical location of a device.

  • True
  • False

Question 9: Using a blockchain network for IoT Asset Tracking is an important blockchain use case because it can be used to record an immutable record of the following attributes. Select all that apply.

  • Where the asset was located during its journey
  • How long the truck driver took a lunch break
  • When was the asset at a particular location
  • What environmental conditions (temperature, vibration) the asset was exposed to

Question 10: The Particle Electron program is written in which language?

  • Java
  • C/C++
  • Python
  • Go
