Incorrect data split ratio might be a problem too.

Wait, how can the model just get worse without changes?

Too few layers could be a factor, but not the main issue.

I think it's poor data quality, honestly.

Definitely lack of model retraining!

I think the model might just be too simple. Option C sounds plausible, but I’m not entirely convinced.

I’m not so sure about that. Could it also be poor data quality? I feel like we went over that in class, but I can't recall the specifics.

I remember we discussed how models can degrade over time if they aren't retrained. I think option B might be the right answer.

I remember a practice question about data splits affecting model performance. Option D could be relevant, but it seems less likely than retraining issues.

Okay, let's think this through. The question is asking about the Designated Router (DR) on the OSPFv3 network. Since the command output on R3 shows that R1 and R2 are the DRs, the answer must be TRUE.
