The genesis block's hash is not stored in every block, right?

Wait, are we sure about that? Sounds a bit off.

I thought it was just the ID of the previous block?

The hash of the previous block is definitely in the current block's header!

This seems like a pretty straightforward question. I think I'll go with option A, "Back scheduling", since the description matches the process of working backwards from the due date.

I think the key here is to look for a command that specifically mentions "TLOC" and "summary". That seems to be the focus of the question.

Okay, I've got this. The key drawbacks are that the approach is too infrequent to adapt to changes, it doesn't guarantee competitive advantage, and it relies on unreliable assumptions about the future. I'm confident I can nail this question.

This seems straightforward to me. The problem is clearly that the policy was not committed after creation, so option D is the correct answer.

Process of elimination time. Private banking seems too regulated, and trade finance is probably too monitored. I'm leaning towards alternative remittance.
