D makes sense, blocks can be replicated across DataNodes.

I think A is misleading, they do check data validity sometimes.

B is correct, DataNodes do send blocks to NameNode.

I feel like I read something about blocks being unique across DataNodes, but I can't recall if that was a strict rule.

I think option B sounds familiar because I practiced a question about how DataNodes communicate with the NameNode.

I remember that DataNodes are responsible for storing data blocks, but I'm not sure about the validity checks.

I’m leaning towards option D since blocks can be replicated across DataNodes, but I’m not entirely confident.

Okay, I've got this. The key is to use a custom event. The child component can fire the event, and the parent can listen for it and then handle the navigation. Simple!

Hmm, I'm a bit confused on this one. I know there's something related to licensing in the interface, but I can't remember exactly where it's located. I'll have to think this through carefully.
