Consider the following:
- Router R2 is an ABR in OSPF Areas 0 and 1.
- Router R2 advertises the aggregate prefix 10.10.10.0/24 into Area 1.
- Router R1 in Area 0 generates LDP labels for FECs 10.10.102/31 and 10.10.10.4/31
Router R3 in Area 1 places these FECs in its LIB, but it does not place them in its LFIB. What can you do on router R3 to make it populate these labels in its LFIB?

Just to clarify, R3 needs to accept those FECs to populate LFIB.

Wait, why would disabling exact match help? Sounds off.

Not sure about that, C might be better.

R2 is definitely an ABR for OSPF Areas 0 and 1.

Disabling LDP exact match sounds familiar, but I can't recall if that would actually help with getting those labels into the LFIB.

I practiced a similar question where creating an import policy helped with FECs, so that could be a viable option here too.

I think enabling LDP aggregate prefix match might be the solution, but I need to double-check how that affects the LFIB population.

I remember something about LDP and how it interacts with OSPF, but I'm not sure if disabling route summarization is the right move here.

Ah, this is a tricky one. I'm a bit confused between the different permission sets here. I'll have to review the details of each option to make the best guess.

Hmm, I think I might know the answer to this one. If the Interactive Client is only being used for controlling and monitoring the Blue Prism environment, and not running automations locally, then the "Sun the process engine" setting should be disabled, right?

The country of origin requirement is an interesting detail. I'll make sure to double-check that in the exam.

I think system testing being delayed makes sense, especially with all the new features being added. It might be a significant risk.

Ah, the joys of OSPF and LDP! Option C is the way to go, unless you want your router to be as lost as a sheep in a wolf pack.

Disabling route summarization on router R3 could also be a possible solution to populate the labels in the LFIB.
CY

I think enabling LDP aggregate prefix match might also work in this scenario.

I agree, option C is the best choice to make sure the labels are populated in the LFIB.

Haha, 'Disable LDP exact match' - that sounds like a recipe for disaster! I'll go with Option C, just to be safe.

Creating an import policy to accept those FECs is a good way to go.

I'm not sure about this one. Disabling route summarization on R3 or enabling LDP aggregate prefix match don't seem relevant to the problem statement.

C) Create an import policy to accept these FECs
GA

A) Disable route summarization on router R3
HE

I'm not sure about the answer. Maybe disabling LDP exact match on the specified FECs could also be a solution.
DI

I agree with Dominque. Enabling LDP aggregate prefix match might also work.

Option C looks like the correct answer. We need to create an import policy on R3 to accept the FECs advertised by R1 in Area 0.
SH

That makes sense, we just need to accept the FECs from R1 in Area 0.
