I think D might be misleading, not sure about that one.

C is definitely true, MAC learning cuts down on flooding.

Wait, are you saying D is false? That sounds odd!

I agree, B is correct too, flooding helps with learning.

A is true, PE routers do learn MAC addresses.

I thought MAC learning was supposed to reduce flooding, so that one seems correct to me. Maybe the one about multiple VPLSes is the false statement?

I feel like the statement about multiple VPLSes sharing the same MAC FDB could be the false one, but I can't recall the details.

I remember practicing a question about MAC learning and flooding, and I think flooding is necessary for all PEs to learn source addresses.

I think the PE routers learning MAC addresses is true, but I'm not completely sure if that's the right answer here.

Okay, let me try to break this down. The IT 5 Roles are Stakeholder, Owner, Management, Governing Body, and something else. I think Management is the one that deals with operations, but I'm not 100% certain. I'll have to review my notes to be sure.

I've used "vxassist" before for storage management, but I don't think that's the right command here. I'm leaning towards "vxdiskunsetup" as the best option to securely clean the data.

Okay, I remember learning about this in my Cisco collaboration class. I believe the correct answer is the DNS SRV query for the Cisco UDS service, which is used for Jabber client login and provisioning.
