Wait, can the ICL really be encrypted? That's surprising!

D is definitely not right, ICL isn't for management.

I thought the ICL could be encrypted too, so C is a yes!

I practiced a question similar to this, and I think the ICL does use a separate routing instance, but I’m not 100% sure about the Layer 2 aspect.

I feel like the ICL is related to device management, but I’m uncertain if that’s the main function in an HA setup.

I think ICL traffic can be encrypted, but I can't recall if it uses a separate routing instance for communication.

I remember studying the ICL, but I'm not sure if it's strictly Layer 2 or if it can operate at Layer 3 as well.
