Blockchain CBDE Exam - Topic 3 Question 32 Discussion

Function and Variable Visibility:
A) a function that is marked as internal cannot be called by other contracts, unless the function is used by a derived contract. Private Functions cannot be called by any other outside contract and public variables are generating automatically a getter function.
B) a function that is marked as external can never be called internally. Private functions can also be called by derived contracts using inheritance. Private variables are accessible also in derived contracts.

Wait, private functions can’t be called by derived contracts? That’s surprising!

Okay, I think I've got this. I'll select option A to register the devices and sign the app. That seems like the most straightforward solution.

Hmm, I'm a bit unsure about the difference between syncing non-recurring events and syncing recurring events. I'll need to read through the options carefully.

I recall discussing how incentivizing challenging the status quo can lead to risky behaviors in our case studies. So maybe B is right, but D could fit too.

Hmm, I'm not sure about this. I'll have to review the networking concepts again.
