Selected Answer: B
OSPF LFA (Loop-Free Alternates) is a technique used to reduce micro loops in a network. Micro loops occur when there is a temporary inconsistency in the routing information, leading to packets being forwarded in loops between routers. LFA provides backup alternate paths that allow packets to be forwarded in a loop-free manner, reducing the impact of micro loops and improving network stability.
