A and D are spot on! Good choices!

Wait, are you sure about C? That sounds off.

A and C seem right to me.
RA

I thought B was part of it too?
JO

Definitely A and D! Those are key functions.

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.
MI

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

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

This question seems tricky, but I'll review my notes on MPLS and try to eliminate the incorrect options.

Ah, I remember learning about MPLS in class. Let me apply that knowledge to figure out the right functions for the control plane.

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.

Hmm, I'm a bit unsure about the differences between the MPLS control plane functions. Let me think this through carefully.

This looks like a pretty straightforward MPLS question. I'm confident I can handle this one.

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.

E) Routing lookups.
JE

I agree, label swapping is outdated.
VA

D) Label signaling.
LA

A) Label allocation and management.
DO

Haha, label swapping? What is this, a game of musical chairs? I'm going with A and D.
XE

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.
SU
Suzi

Yes, pushing a label on an unlabeled packet and performing label signaling are key functions of the MPLS control plane.
KI

Label allocation and management, as well as label signaling, are important tasks for the control plane.
TA
Tamra

I agree, A and D are the correct functions of the MPLS control plane.
SO

I'm not sure about E) Routing lookups. Can someone explain why it might be a function of the MPLS control plane?
CE
Cecily

I agree with Annamae. I also think D) Label signaling is another function of the MPLS control plane.
ET
Ettie

A and D seem like the correct functions of the MPLS control plane. I'm not sure about the other options though.
AN
Anabel

Routing lookups are not part of the MPLS control plane.
MA
Marguerita

Label swapping is also a key function for MPLS.
WE
Wenona

I agree, label allocation and management as well as label signaling are important.
IZ
Izetta

I think A and D are correct functions of the MPLS control plane.
AN
Annamae

I think A) Label allocation and management is definitely a function of the MPLS control plane.
