Q: 7
Refer to the exhibit. 
R101 is peering with R102 and R103, and R201 is peering with R202 and R203 using iBGP Labeled Unicast address families. The OSPF area 0 border routers are in a full iBGP Labeled Unicast mesh, and VPNv4 routes are exchanged directly between PE routers R101 and R201 through iBGP Which address family-level configuration must be applied on ABR R102 on ABR R102 to support a Unified MPLS routing architecture with partitioned IGP domains? A) 
B) 
C) 
D)

Option B pretty sure since some lab guides show similar config. Check official guide and look over exam practice too.
B , looks like it could work because it sets up iBGP but I'm missing the labeled unicast part for partitioned domains. Maybe I'm overthinking and B is fine since VPNv4 is exchanged directly. Not 100% though, anyone see B as valid?
I think A for this, since with partitioned IGP in Unified MPLS you need the labeled unicast address family set right on the ABR. B looks convincing at a glance but it leaves out that key iBGP label signaling step. I think A lines up with exam guides, but not 100% if anyone disagrees.
Option A
B for me, config looks closer to what I've done in MPLS labs. Not fully sure though, could be missing something here.
A , B is tempting but misses the labeled unicast config needed for partitioned IGP.
A is the one you want here. The partitioned IGP domains for Unified MPLS require that iBGP labeled unicast config, which only A shows. The other options leave that out. Pretty sure on this but open to other takes if anyone disagrees.
Maybe A, but I'd double-check with the official guide or some lab configs to be sure.
A for sure. Only A shows the iBGP labeled unicast address family on R102, which is a must with partitioned IGP domains for Unified MPLS. That labeled config isn’t in B or the others. Pretty confident here unless there’s a weird scenario I missed.
Pretty sure it's A, since unified MPLS with partitioned IGPs needs the iBGP labeled unicast config and that's only in Option A. B seems like a classic trap by skipping that detail. Correct me if I'm missing something though.
