I’m not sure about A, isn’t there some cost involved even locally?

C is crucial, regression bugs can really mess things up.

Wait, you can’t access logs on Main-Net? That’s wild!

I practiced a question similar to this, and I think running tests quickly is a big advantage, but I’m torn between A and B.

I feel like option C is really important too, especially with how often contracts get updated on the main-net. I just hope I don't mix up the reasons during the exam.

I think option B makes sense because logging is crucial for debugging, but I can't recall if it's the only benefit of local testing.

I remember we discussed how testing on a local chain can save costs, but I'm not sure if that's the main reason.

I'm not totally sure about this one. The logging aspect in option B sounds important for debugging, but I'm not convinced that's the main reason for unit-testing on a local chain. I'll have to review my notes on this topic again.

I agree with Charlene, option A seems like the most obvious answer. Being able to run tests for free and quickly on a local chain is a huge advantage compared to the main network. The other options don't seem as directly relevant.

Hmm, I'm a bit confused. Is it really just about saving money on fees? I feel like there must be other important reasons for unit-testing on a local chain. I'll have to think this through more carefully.

This question seems straightforward. I think the answer is A - running tests quickly and cheaply on a local chain is the main benefit of unit-testing.

This looks like a good opportunity to apply the concepts we've been learning. I feel pretty confident I can narrow down the options and select the correct answer.

Okay, I remember learning about this in class. Cryptocurrencies are indeed considered securities and regulated by the SEC. I'll select True.

Hmm, I'm a bit unsure about this one. The question mentions ensuring the Compliance team can't see other reports, so I'm wondering if the Deployment Server might be the right answer to control access to knowledge objects.

Okay, I know ST&E is used for risk assessment, so I'll look for the options that mention discovering vulnerabilities and enforcing security policies.

I recall a practice question where we analyzed the relationship between spot and futures prices. If the futures price is indeed trading higher, it makes sense that this strategy might be inappropriate. But I might need to revise that concept.

I remember studying some examples of manufacturing types, but it feels a bit confusing. Is Repetitive manufacturing the same as Continuous?

I think I've got a good handle on this. The key things to remember are that data is encrypted and certificates are required. The other options seem a bit more tricky, so I'll need to carefully consider each one.

Okay, I think I've got this. The key is to integrate the DNS and networking infrastructure between the two organizations as efficiently as possible. I'll focus on the options that allow for quick integration with minimal downtime.

Unit-testing on a local chain? More like 'fun-testing' if you ask me! Seriously though, it's the only way to go. Who wants to pay gas fees just to find a bug?

C) to avoid regression bugs with contracts that are updated constantly on the main-net. Once you update a contract on the main-net, the address stays the same, but the code changes and this can have disastrous side-effects.

B) to run tests in an environment where logging is activated. On the Main-Net you have no access to transaction logs and this is ultimately the information you need to debug your contracts.

A) to run tests quickly and especially for free, compared to continuous deployment on the MainNetwork. This way you save a lot of fees, time and costs.

Avoiding regression bugs is so crucial, especially with constantly updated contracts. I don't want to risk breaking something on the MainNet. Local testing is the smart choice.

You make a great point about the logging. Debugging on the MainNet would be a nightmare without those transaction logs. Local testing is the way to go.

Running tests on a local chain is definitely the way to go. I can't imagine the fees I'd have to pay to test on the MainNet. Gotta save those precious Ether coins!
