When a router receives an update for its routing table, what is the metric value change to that path?
The correct answer is C. Increased by 1. In distance-vector routing protocols such as RIP (Routing Information Protocol), each router that receives a routing update increments the hop count metric by 1 before propagating it further. This accounts for the additional hop (router) the packet must traverse. The metric…

Explanation
In distance-vector routing protocols such as RIP (Routing Information Protocol), each router that receives a routing update increments the hop count metric by 1 before propagating it further. This accounts for the additional hop (router) the packet must traverse. The metric represents the distance (in hops) to a destination network. RIP has a maximum hop count of 15; 16 is considered unreachable. This hop-count increment is fundamental to how distance-vector protocols calculate the best path.
