D sounds fancy, but is it really necessary for firmware updates?

B is good for storage, but it doesn't stop malware from being injected.

Wait, can we really trust all certificates? Seems risky.

I think C is just as important. Only trusted admins should handle updates.

A is a must! Signed updates are crucial.

IPSec sounds familiar, but I can't recall if it directly prevents malware. I think it just secures the communication channel, right?

I feel like we had a practice question about restricting firmware updates to trusted admins. That could help, but I'm not sure if it's enough on its own.

I'm not entirely sure, but I think encrypting the updates is more about protecting data in transit rather than preventing malware.

I remember we discussed the importance of signing firmware updates with a trusted certificate in class. That seems like a solid option.

Okay, I think I've got a handle on this. I'll start by identifying the true statements, and then double-check my reasoning to make sure I'm not missing anything.

Ah, I see. If you do the cleansing before partitioning, then the training and test sets will both be affected, making it harder to assess the model's true performance. Doing it after partitioning keeps the test set clean and unaffected.

Alright, I think I've got it. The answer that's not a common impact is C - conflicts when also applying the Decoupled Contract pattern. Feels like a solid choice.

Hmm, I'm not sure about this one. The question is asking about applying the technology, but the passage doesn't explicitly say we should use it everywhere. I might need to think this through a bit more.
