An OSPF stub area blocks which types of LSAs from being injected into the area by the ABR? (Choose two.)

  • Type 1 LSA
  • Type 3 LSA
  • Type 4 LSA
  • Type 5 LSA

Explanation: An OSPF area blocks the injection of Type 5 LSAs into an area and inserts a default route instead. Because Type 5 LSAs are blocked, there is not a need for a Type 4 LSA, so those are blocked as well.
