Dynamic Routing, also called adaptive routing, describes the capability of a system, through which routes are characterized by their destination, to alter the path that the route takes through the system in response to a change in conditions. The adaptation is intended to allow as many routes as possible to remain valid (that is, have destinations that can be reached) in response to the change.

Question 119
Drag and Drop Question Match the networking topologies to their corresponding characteristics. To answer, drag the appropriate topology from the column on the left to its characteristic on the right. Each topology may be used once, more than once, or not at all. Each correct match is worth one point.
Correct Answer:
Explanation: * Star In star topology, every node (computer workstation or any other peripheral) is connected to a central node called a hub or switch. * Ring Each device present in Ring Topology is incorporated with a REPEATER. * Mesh Fully connected mesh topology: A fully connected network is a communication network in which each of the nodes is connected to each other. * Star In star topology, every node (computer workstation or any other peripheral) is connected to a central node called a hub or switch. * mesh (full) The major disadvantage is that the number of connections grows quadratically with the number of nodes,as per the formula: c=n(n-1)/2 * Ring Ring Topology: In this type of Topology, data is passed from one node to another in a series. Here each device has dedicated Point-to-Point connection, with only two devices present on either side of it.
