Which of the following types of information is used to calculate the Shortest Path Tree (SPT)?
The correct answer is C. Network topology. The Shortest Path Tree (SPT) is calculated by Link-State routing protocols like OSPF and IS-IS A complete map of the network topology. Each router uses algorithms like Dijkstra's to compute the shortest paths to all destinations.
