List a distance vector advantage.

• A. It scales well to large networks
• B. It provides fastest convergence
• C. Simple to understand and configure
• D. It requires full topology knowledge

Answer: (C)

Distance-vector routing is prized for its simplicity: each router only needs to know the distance to destinations through its immediate neighbors and shares that basic information with them. This makes setup and ongoing configuration easy, so you can get a network running with minimal fuss. You don’t have to build or maintain a complete, detailed map of the entire network, which keeps administration straightforward. That ease of understanding and configuration is the primary advantage. Of course, this simplicity comes with tradeoffs: it doesn’t scale well to large networks and convergence can be slower, and people often contrast it with approaches that require full topology knowledge.
