Which option is an example of a static routing protocol?

1. Open Shortest Path First (OSPF)

2. Border Gateway Protocol (BGP)

3. Routing Information Protocol (RIP)

4. Split horizon

The correct answer is: Border Gateway Protocol (BGP)

The correct answer is Border Gateway Protocol (BGP), which is indeed a routing protocol but should not be classified as static. However, understanding why the other protocols and concepts are relevant can help clarify the distinction. Static routing refers to the manually configured routes in a networking environment that do not change unless they are manually updated. BGP, on the other hand, is a dynamic routing protocol used primarily to exchange routing information across the internet and is not static in nature. Open Shortest Path First (OSPF) and Routing Information Protocol (RIP) are also dynamic routing protocols designed to automatically update routes based on network changes. OSPF uses a link-state routing algorithm, while RIP employs a distance-vector algorithm, both of which dynamically adapt to changing network conditions. Split horizon is a routing technique used with distance-vector protocols to prevent routing loops, and it is not classified as a routing protocol itself, but rather a method for optimizing routing information. In summary, a true example of a static routing protocol would refer to methods of routing where routes are manually configured and remain constant. Neither BGP, OSPF, nor RIP fit this classification, while split horizon describes a method rather than a protocol.
