Discuss Blockchain CBDE Exam Topic 5 Question 73

When solidity is compiled then also Metadata is generated:

Athe 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.

Bmetadata contains the address, and the size of the smart contract. The ABI Array is generated externally upon deploying the smart contract.

Cthe 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.

C seems a bit misleading, migration tools just help deploy, right?

B sounds off, the ABI is definitely part of the metadata.

Yuette 12 months ago

Wait, I thought the ABI was generated during deployment?

Truman 12 months ago

Totally agree with A, that's how it works!

Samira 12 months ago

A is correct! Metadata includes the ABI and contract address.

I thought the metadata was generated by the compiler, but now I'm questioning if migration software plays a role in that process.

I feel like option A makes the most sense since the ABI is definitely needed for interaction, but I might be mixing up some details about deployment.

I think I saw a practice question that mentioned the ABI is generated during compilation, but I can't recall if the address is part of that metadata.

Ronny 1 year ago

I remember that the ABI is crucial for interacting with the smart contract, but I'm not entirely sure if the address is included in the metadata.

This seems like a classic case of an imbalanced dataset. Oversampling the disease cases would be the way to go to avoid the overfitting problem. The low base rate makes simple random sampling less ideal.

Okay, let me think this through. S&OP is about bridging the gap between the business plan and operations, so I'm guessing the answer has to do with evaluating the feasibility of those plans. I'll go with B.

Okay, this seems straightforward. The workflow rule is set to evaluate on creation and edit, so that's probably what's causing the double creation of the Account Plan record. I'll mark that as my answer.

Hmm, this looks like a regular expression question. I'll need to carefully analyze the pattern and compare it to each option.
