Chaincode interface must be implemented by ever chaincode program.

  1. TRUE
  2. FALSE

Answer(s): A



Which of the following would not be a good use case for Hyperledger Fabric?

  1. Cryptocurrency Exchange
  2. Compliance Ledger
  3. Business Contracts
  4. Asset Exchange

Answer(s): A

Explanation:

Hyperledger Fabric is an enterprise permissioned blockchain. It does not have a cryptocurrency nor token. It could be a use case to develop chaincode to create an off chain channel to a cryptocurrency exchange but this would not be efficient.



Hyperledger is a membership based distributed ledger platform. What determine the level of permissions required to transact for members?

  1. Authentication Services
  2. Validator Services
  3. Identity Management
  4. Audit Services

Answer(s): B

Explanation:

Hyperledger is a private validator network protocol. All the entities in a network must register with membership services to obtain an identity with access and transaction authority on the network. Validators determine the level of permissions required to transact. The network setup also defines the network as permissive, allowing the ease of access. It supports for rapid and high adoption for a more controlled and restrictive environment.



Hyperledger supports two types of transactions. What are the two types? (Select two.)

  1. Code Provisioning Transaction
  2. Code Provisioning Transaction
  3. Code Deploying Transaction
  4. Code Invoking Transaction
  5. Code Declaring Transaction

Answer(s): C,D

Explanation:

Code deploying transaction Code deploying transaction submits, updates or terminates a chaincode. The validating nodes protects the authenticity and integrity of the code and its executing environment. Code invoking transaction Code invoking transaction is an API call to a chaincode function. It is similar to how a URI invokes a servlet in JEE. The displayed function is called upon the instantiation of the chaincode. Each chaincode maintains its own state and a function call is made to trigger chaincode state changes.
