Referring to the exhibit, what is the shortest path from R6 to R5?
Why is it not R6 R4 R5?
Sorry – R6 R5 R2 R3 R5 ?
I think the correct is R6 R4 R2 R3 R5, cause this path has the lowest cost.
I think as R6 and R5 are in the same area the direct link is preferred. Intra-area link is preferred over Inter Area.

My simulation using GNS3 says answer B is correct.
R6-> R4 -> R2 -> R3 -> R5
I believe D is correct if R5 interface is in same area (Area 2 in this case) as R6 which makes all the other routes advertised as inter area. OSPF will chose intra area over inter area. Not clear from the question but R6-R5 will be chosen in that scenario.

Please read this article, it says all you need to know. R6-R5 is correct answer:

R6-R4-R5 is the answer
it is BOTH intra-area AND the lowest cost.
D is the correct answer. For JM: the link between R4 and R5 isn’t in area 2, but 0.
questions is ambiguous. it depends. if the source is R6, then D is correct. its directly connected regardless of cost. AD for directly connected routes is 0 and therefore preferred. If behind R6 it should be C – intra-area because its intra-area
I agree with Jun. Nothing in the question says OSPF, so any route in R6 towards R5 is considered, which would include directly-connected route. That route would be preferred over any OSPF route.
image has OSPFv3 Area
D is correct Answer
