I feel like pushing a label on an unlabeled packet might be involved, but I can't recall if it's specifically a control plane function.

I’m a bit confused; I thought label swapping was part of the data plane, not the control plane.

I remember practicing a question similar to this, and I think label signaling is also a key function of the MPLS control plane.

I think label allocation and management is definitely one of the functions, but I'm not sure about the second one.

Okay, I know MPLS has to do with label switching, so I'm guessing the correct answers are related to that. I'll give it my best shot.

Wait, so the control plane is like the conductor of the MPLS orchestra, and the data plane is the instruments playing the tunes? I'm going to need a diagram for this one.

Label allocation, management, and signaling - that's the control plane's job. I can't believe they're even asking about label swapping, that's so 90s.

Definitely A and D. Pushing a label on an unlabeled packet is more of a data plane function, and label swapping is also a data plane operation.
