Question 1.
In a network of LANs connected by bridges, packets are sent from one LAN
to another through intermediate bridges. Since more than one path may
exist between two LANs, packets may have to be routed through multiple
bridges.Why is the spanning tree algorithm used for bridge-routing?



  1.    For shortest path routing between LANs
  2.    For avoiding loops in the routing paths
  3.    For fault tolerance
  4.    For minimizing collisions
Explanation:-
Answer: Option A. -> For shortest path routing between LANs
