I vaguely recall a case study about a private blockchain that was centralized. That makes me lean towards false for this question.

I thought all blockchains were decentralized, but now I’m second-guessing myself. There were practice questions that mentioned exceptions.

I’m not entirely sure, but I feel like we went over examples of both decentralized and centralized blockchains in class. Maybe it’s false?

I remember discussing how some blockchains can be centralized, like those used by certain companies. So, I think the answer might be false.

I'm a little unsure about this one. Is DDoS protection implemented at the network layer or the application layer? I'll have to review my notes to be sure.

I'm not entirely sure if risk reporting is a bad thing as stated in B. It seems more complicated than that.

Hmm, I'm not sure about the card states feature. I'll need to review that one more closely to see if it could work for this scenario.

I'd definitely go with filing a suspicious transaction report. The bank has clear protocols for these situations, and you want to protect the institution.
