Which of the following devices can originate an opaque LSA?

Answer options

• A. TE enabled OSPF routers
• B. Backbone router only
• C. ABR only
• D. ASBR only

Correct answer: A

Explanation

The correct answer is A because only Traffic Engineering (TE) enabled OSPF routers have the capability to originate opaque LSAs, which are specific to OSPF extensions. Options B, C, and D are incorrect as Backbone routers, Area Border Routers (ABRs), and Autonomous System Boundary Routers (ASBRs) do not originate opaque LSAs.
