With reference to the exhibit, which path would traffic traversing R1 use to reach R4?

  • A R1 -> R3 -> R4
  • B R1 -> R2 -> R3 -> R4
  • C R1 -> R2 -> R4
  • D R1 -> R4
Explanation

OSPF forwards traffic along the path with the lowest total cost. The route R1 → R2 → R4 has a cumulative cost of 10, which is lower than the direct R1 → R4 cost of 15 and the R1 → R3 → R4 cost of 15.
