What is used to choose the best path on a virtual router that has two or more different routes to the same destination?
The metric is used to choose the best path on a virtual router that has two or more different routes to the same destination. The metric evaluates the cost of each path and selects the one with the lowest cost, ensuring efficient routing decisions.
The ideal question will be what to do in case of having multiple dynamic routing protocols taking to the same destination then... it will be the administrative distance. If we have just one single routing protocol but multiple routes to the same destination, let;s say statis routes... then it is the metric.. in case of the dynamic protocols, the routes with lower priority will always be installed in the FIB but it depends on the admin distance of the protocol.
So, It is option A.
