Which two statements are correct about Opaque LSAs in OSPF? (Choose two.)

Answer options

• A. Type 10 LSAs are used for MPLS traffic-engineering and have area scope.
• B. Type 11 LSAs are used for MPLS traffic-engineering and have area scope.
• C. Type 11 LSAs are used for MPLS label exchange and have link-local scope
• D. Type 9 LSAs are used for graceful-restart and have link-local scope

Correct answer: A, D

Explanation

The correct answers are A and D. Type 10 LSAs (A) are indeed used for MPLS traffic-engineering with area scope, while Type 9 LSAs (D) are related to graceful-restart and have link-local scope. Options B and C are incorrect because Type 11 LSAs are not used for MPLS traffic-engineering but rather for Opaque LSAs with a different scope.
