CompTIA Network+ (N10-008) — Question 175

Which of the following protocols is widely used in large-scale enterprise networks to support complex networks with multiple routers and balance traffic load on multiple links?

Answer options

• A. OSPF
• B. RIPv2
• C. QoS
• D. STP

Correct answer: A

Explanation

OSPF (Open Shortest Path First) is an interior gateway protocol that efficiently handles routing in large and complex networks, making it suitable for environments with multiple routers. RIPv2, while also a routing protocol, is less scalable and not typically used in large networks. QoS (Quality of Service) pertains to managing network traffic but is not a routing protocol, and STP (Spanning Tree Protocol) is used for preventing loops in network topologies rather than for routing traffic.
