CompTIA N10-009 Exam - Topic 2 Question 41 Discussion
Topic #: 2
Which of the following internal routing protocols is best characterized as having fast convergence and being loop-free?
The correct answer is OSPF (Open Shortest Path First). OSPF is a link-state routing protocol known for its fast convergence and use of the Dijkstra algorithm to calculate the shortest loop-free path. It efficiently scales to large enterprise networks and avoids routing loops by maintaining a complete topology map.
A . BGP is primarily an external routing protocol used between ISPs, not internal.
B . STP is not a routing protocol; it prevents loops at Layer 2.
D . RIP is an older distance-vector protocol with slower convergence and a maximum hop limit of 15.
OSPF's design makes it the preferred internal gateway protocol (IGP) for medium-to-large organizations requiring speed and loop-free reliability.
