World of Computer Networking Your CCNA start - Multiple Route Paths

The lecture covers the differences between BGP, GP, IG, and other routing protocols, focusing on distance vector and link state protocols. It explains alternative routes to remote networks using a network diagram with routers R1, R2, R3, and R4. The lecture discusses how different routing protocols select routes based on specific metrics and concludes with a preview of the next lecture on metrics.

What is one key difference between distance vector and link state routing protocols?

• Distance vector protocols calculate the shortest path using Dijkstra's algorithm.

• Distance vector protocols use a complete map of the network.

• Link state protocols have a faster convergence time.

• Link state protocols rely on periodic updates from neighbors.

In the given network diagram, which router is directly connected to both R1 and R4?

• R4

• R3

• R2

• R1

How can router R2 reach a remote network according to the lecture?

• Directly via R1

• Directly via R4

• Only via R3

• Only via R4

What is the first step a router takes when it receives a specific network from a neighbor?

• Inserts it into the routing table

• Calculates the metric

• Inserts it into the routing database

• Selects the best route

What factor influences the selection of the best route by different routing protocols?

• The number of routers in the network

• The approach to calculation of the metric

• The type of data being transmitted

• The speed of the network connection
