Name and briefly describe three common dynamic routing protocols and a key characteristic for each.

• A. RIP (Distance-vector, hop count 15); OSPF (Link-state, areas, SPF); BGP (Path-vector, policy-based).
• B. RIP (Distance-vector, hop limit 15); OSPF (Link-state, areas, SPF); BGP (Path-vector, policy-based).
• C. BGP (Link-state, SPF); OSPF (Distance-vector, hop count 16); RIP (Path-vector).
• D. OSPF (Path-vector, policy-based); RIP (Link-state); BGP (Distance-vector).

Answer: (B)
