HPE Aruba Certified Mobility Professional (ACMP) — Question 12

How far do OSPF link state updates (LSUs) for Type 1 (Router) and Type 2 (Network) LSAs propagate?

Answer options

• A. to every OSPF router in the local area
• B. to every OSPF router in all areas
• C. to every OSPF router in the local area and the backbone
• D. to every OSPF router in the network to which the LSU applies

Correct answer: B

Explanation

The correct answer is B, as OSPF LSUs for Type 1 and Type 2 LSAs are designed to propagate to every OSPF router in all areas to ensure consistent routing information throughout the entire OSPF domain. Option A is incorrect because it limits the propagation to just the local area, while C restricts it further by excluding routers in other areas. Option D misrepresents the scope by suggesting it is limited to a specific network instead of all areas.
