I thought E-pipes learned MACs too, this is confusing!

I vaguely recall something about SAPs being the demarcation point, but I can't remember if that applies to both E-pipes and VPLSes.

I’m not entirely sure, but I feel like E-pipes don’t learn MAC addresses like VPLSes do, which makes D sound like the false one.

I think I saw a practice question about SAP encapsulations, and I’m pretty sure both support dot1Q and Q-in-Q, so B might be true.

I remember studying that both E-pipes and VPLSes operate at Layer 2, so A seems correct to me.

I've got a good feeling about this one. I remember learning about the storage locations for the NCS 2006 database, so I think I can narrow it down.

I'm a bit confused on this one. The switch should be able to detect malware, so I'm not sure why it didn't in this case. I'll need to review the details carefully.

I'm just glad they didn't ask about the difference between E-pipes and plumbers. That would have been a real head-scratcher!

Option D? More like Option 'Dee-fective', am I right? Just kidding, but it does seem like the obvious incorrect choice here.

Option D seems to be the correct answer. E-pipes don't learn MAC addresses, they simply forward frames based on the port, while VPLSes do learn MAC addresses.
