Explanation
Correct Answer: A. Routing loops
- Split-horizon is a routing technique used to prevent routing loops by ensuring that a router does not advertise a route back out of the interface from which it was learned. This avoids situations where packets endlessly circulate between routers due to incorrect routing information.
Why the other options are incorrect:
-
Duplicate addresses:
- Split-horizon does not address IP address duplication. Duplicate addresses are typically resolved by properly managing IP address assignment (e.g., using DHCP or static IP planning).
-
Network collisions:
- Network collisions occur in shared medium environments (e.g., hubs or half-duplex networks) and are unrelated to split-horizon, which addresses routing issues at Layer 3.
-
Large routing tables:
- Split-horizon does not reduce the size of routing tables. It prevents routing loops but does not optimize or prune routing table entries. Large routing tables are typically managed with route summarization or default routes.
