Nokia 4A0-105 Exam - Topic 5 Question 98 Discussion

What function in IEEE 802.1 ah helps to limit the amount of MAC addresses learned in the core?
B) The B-VPLS and l-VPLS are configured in the edge. The B-VPLS is configured with a Backbone MAC and is the only MAC learned in the core
A) I-VPLS is configured in the core of the network with an l-MAC address. This l-MAC address is the only MAC learned in the core
C) Each SDP is configured with a Backbone MAC to hide customer MAC addresses in the core
D) Each SAP is associated with a common l-MAC to hide customer MAC addresses in the core

Each SDP with a Backbone MAC is definitely the way to go!

B-VPLS is key for Backbone MACs, not just I-VPLS!

Wait, so only one MAC is learned in the core? That seems odd.

I-VPLS uses an l-MAC in the core, right?

I feel like D could be correct since it mentions SAPs and l-MACs, but I’m a bit confused about how they relate to limiting MAC addresses.

C sounds familiar because I remember discussing Backbone MACs hiding customer MACs, but I’m not confident it’s the right choice.

I recall something about B-VPLS and l-VPLS from practice questions, but I can't remember if they specifically limit MAC addresses in the core.

Ah, I see. The Backbone MAC is used to hide the customer MAC addresses in the core, so the answer must be C. Each SDP is configured with a Backbone MAC for this purpose.

I'm feeling pretty confident about this one. I think the answer is A. The I-VPLS is configured in the core with an l-MAC address, and that's the only MAC address learned in the core.

Okay, let me think this through. I believe the key is that the function in IEEE 802.1ah is designed to limit the number of MAC addresses learned in the core. So the answer is likely related to either the l-MAC address or the Backbone MAC.

Hiding customer MAC addresses in the core? Sounds like the network is playing a game of hide-and-seek. Where's Waldo?

I'm a bit torn between B and D, but I think I'll go with B. It just makes more sense to me to have the Backbone MAC at the edge rather than associating each SAP with a common l-MAC.

Option B seems the most logical choice here. By configuring the B-VPLS with a Backbone MAC, the customer MAC addresses are hidden from the core, limiting the number of MAC addresses that need to be learned.
