I thought the P flag was always set to 0 in these cases?

Wait, are we sure about the non-zero Layer-2 MTLJ? Seems off.

I think option D is the correct one, all PES should advertise that.

I have a vague memory of the P flag being important, but I can't remember if it should be set to I or something else.

I'm leaning towards option D because I remember that MAC routes usually involve MPLS labels, but I could be mixing it up with another topic.

I feel like I saw a similar question about MTLJ in our practice tests, but I can't recall if it was specifically for EVPN VPWS.

I think option A might be correct since I remember something about tag IDs in A-D routes, but I'm not entirely sure.

I'm a bit confused by this question. Is it asking about the technical implementation, or more about the conceptual workflow? I'll need to re-read it a few times to make sure I understand what they're looking for.

I'm pretty sure the Startup Panel Administration tab in TIBCO Designer lets you modify the domain membership and user directory, but I'm not sure about the other options. I'll need to double-check the documentation to be certain.

Okay, I think I've got this. The key is that even though the security mechanisms adhere to the same industry standards, the different vendor technologies could still be incompatible. I'll go with option A.

I'm a bit confused because I thought JindoFS could use different back ends, but I can't recall the specifics.
