Blockchain CBDE Exam - Topic 4 Question 89 Discussion

Actual exam question for Blockchain's CBDE exam

Question #: 89
Topic #: 4

[All CBDE Questions]

To develop smart contracts:

Ait's good to start with a local in-memory blockchain with unit tests but then deploy to the mainnet as rapidly as possible.

Bit's good to start with a local in-memory blockchain with unit-tests. Then, in the next step, debug and test the smart contract on a test-net like Ropsten or Rinkeby with beta customers to iron out last issues before deploying it to the main-net.

Cit's good to start with a test-net with beta-customers like on the Rinkeby or Ropsten testnet, before testing it locally on an in-memory blockchain simulation such as Ganache. Then deploy it to the main-net.

I thought you should always test locally first, not the other way around.

I think testing with beta customers is crucial before mainnet.

Wait, why would you deploy to mainnet so quickly? Seems risky!

Totally agree, testing on a test-net first makes more sense.

Starting with a local blockchain is a solid move!

I’m not sure about C; it feels backwards to test on a test-net before a local simulation. I think that could lead to more issues.

I feel like we practiced a question similar to this, and I think B was the answer we chose then too. It just seems safer to test with beta customers first.

I'm a bit unsure, but I thought starting with a local blockchain was the best way to catch early bugs. Maybe A is right?

I remember we discussed the importance of testing on a test-net before going to main-net, so I think option B makes sense.

I think the best approach is to start with the testnet, get feedback from beta customers, and then move to the local in-memory blockchain for more testing. That way, I can make sure the smart contract is working as expected before I even touch the mainnet. Slow and steady wins the race, right?

Okay, I've got this. The key is to start with a local in-memory blockchain and unit tests, then move to a testnet to work out any last issues before deploying to the mainnet. That way, I can ensure the smart contract is rock-solid before it goes live. Gotta be thorough, you know?

Hmm, this is a tricky one. I'm a bit confused about the order of the steps. Should I start with the testnet or the local blockchain? I'll need to review my notes on the development process to make sure I get this right.

I'm feeling pretty confident about this question. I think the best approach is to start with a local in-memory blockchain and unit tests, then move to a testnet before deploying to the mainnet. That way, I can catch any issues early on and make sure the smart contract is working properly.

Hmm, I'm a bit unsure about this one. The question mentions both language and knowledge requirements, so I'm not sure if Skills-based Routing alone will be enough. Maybe we need to look at the other options as well.

I'm a little confused by the wording of this question. I'll need to re-read the choices carefully to make sure I understand what the tool is actually used for.

Okay, I think I've got this. The alarm statuses are normal, warning, and closure. The last option about insufficient data is probably a distractor.

I'm feeling pretty good about option A. The "le 16" qualifier seems to be the most straightforward way to match all the IP prefixes in the specified range. I'm going to go with that as my final answer.

The routing process enabled by default on all interfaces seems like a fundamental feature, but I wonder if it actually makes troubleshooting easier in this case.
