Questão 5 — Simulado CompTIA Network+ N10-009

Explanation: 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.
