I believe B and C are misleading. C can't be right if B is true.

Haha, who even uses IS-IS these days? I'll just stick to EIGRP, it's way easier.

D is definitely wrong, that's way too low. Gotta be B and one of the other options.

I recall that wide metrics are definitely important for scalability, so I think option B is correct about the 16 million limit.

I practiced a question similar to this, and I believe wide metrics do allow for a higher maximum value, like around 16 million.

I think I remember that the default metric value for IS-IS interfaces is actually 63, but I'm not entirely sure.

Wait, I'm a little confused now. I thought the default was 1023 and the wide metrics went up to 16 million. Let me re-read the question and options carefully before answering.

Piece of cake! I know the default IS-IS interface metric is 63, not 1023. And the wide metrics give you a max of 1023, not 16 million. This should be an easy one.

Okay, I think I've got this. The key is remembering that the default IS-IS interface metric has a max of 1023, while the wide metrics expand that to around 16 million. I'll focus on those two options.
