I’m with you all, RRC is the odd one out here.

RRC handles connection management, not RAN-DU.

C) RLC is tricky, but I lean towards RRC too.

Definitely A) MAC and B) Physical layer belong to RAN-DU.

I agree, RRC seems out of place. It's more about signaling.

Wait, are we sure about RLC being in RAN-DU?

Hmm, I'm leaning towards D. RRC, since that's more of a control plane thing.

I'm pretty sure the MAC layer is part of the RAN-DU, but I could be wrong. Gotta double-check that.

The physical layer definitely doesn't belong to RAN-DU, that's just basic networking knowledge.

I feel like RLC is part of the RAN, but I can't recall if RRC fits there too.

Alright, I'll start by listing out the options and seeing which one seems like the odd one out based on my understanding of the 5G RAN.

Wait, is the RRC layer part of the RAN-DU or not? I'm a bit confused on how the 5G architecture is structured.

I remember learning about the RAN protocol stack in class. I think I can narrow this down if I recall the key layers.

I remember practicing a similar question, and I think RRC is more related to the core network, not RAN-DU.

Okay, let's see. The RAN-DU is the distributed unit in the 5G radio access network, so I need to identify which layer doesn't belong there.
