B is just about MAC addresses, not really control plane stuff.

Control plane actions are all about routing decisions!

I’m a bit confused; I thought de-encapsulating was more about data plane functions, but I can't recall clearly.

I practiced a question similar to this, and I think the control plane is definitely about managing routing information, so maybe option C?

I remember something about MAC addresses being related to the data link layer, but I’m not sure if that’s control plane or data plane.

I think control plane actions are more about routing decisions, so I’m leaning towards matching IP addresses to routing tables.

Hmm, this is a tricky one. I'm leaning towards option C, but I'm not 100% sure. I'll need to review my notes on the control plane before making a final decision.

I'm pretty confident that the control plane is responsible for the higher-level network functions, not the low-level data link operations. So I'm going to go with option C.

I'm a bit unsure on this one. The control plane is about managing the network, right? So maybe it's something to do with addressing or discovery, like option D?

Okay, let's see. I think the control plane is responsible for things like routing and forwarding decisions, so option C sounds like the best fit.

Okay, let me think this through. The @Controller annotated classes can render views, and they are discovered via component scanning, so I'll focus on those aspects.

I got this! The answer is C. ns:rebootPhone. You need to reboot the phone to make the configuration changes take effect after the update.

Ha! Imagine if the answer was A - de-encapsulating and re-encapsulating a packet. That would be more of a data plane task, not control plane.

I think D is also a good answer. The Neighbor Discovery Protocol is definitely part of the control plane in IPv6 networks.
