Blockchain BTA Certified Blockchain Developer - Ethereum Sample Questions:
Question 1
When solidity is compiled then also Metadata is generated:
A. metadata contains the address, and the size of the smart contract. The ABI Array is generated externally upon deploying the smart contract.
B. the Metadata contains the ABI Array, which defines the Interface to interact with the Smart Contract. Metadata can also contain the address of the smart contract when it gets deployed.
C. the ABI array and the Metadata are not generated when solidity is compiled to bytecode, its generated by a migration software which deploys the smart contract on the blockchain.
Question 2
A version pragma is a great way to make it clear:
A. for which blockchain a smart contract was developed for. It helps to avoid confusion with beta-customers.
B. for which compiler version a smart contract was developed for. It helps to avoid breaking changes.
C. for which blockchain node a smart contract was developed for. It helps to avoid mixing up different versions of go-ethereum.
Question 3
Truffle has an integrated in-memory blockchain which makes unit-testing very easy:
A. True, but it's still good to use Ganache, or even a real private network for testing.
B. False, it's necessary to use Ganache or even a real private network for testing.
Question 4
Solidity gets compiled:
A. to bytecodes which are essentially opcodes running instruction by instruction.
B. to bytecode that can't be understood by humans.
Question 5
A Blockchain Node:
A. can never become a mining node.
B. can always become a mining node.
