What is the difference between distance vector and link state routing protocol? Distance vector routing protocols are used in the same autonomous system, and link state routing protocol is used in different autonomous system Distance vector routing protocol exchanges the whole routing table, while link state routing protocol exchanges information about all connected networks Distance vector routing protocol is used in private environments, and link state routing protocol is used on the Internet They are both Interior Gateway Protocols. The only difference is in configuration commands

Distance vector routing protocol exchanges the whole routing table, while link state routing protocol exchanges information about all connected networks

Your device has a route to the 0.0.0.0/0 network in a routing table. What route is it, and when will it be used? 0.0.0.0/0 is a default route. The router uses it to route packets if it doesn't have a more specific route to the destination 0.0.0.0/0 is not a valid route 0.0.0.0/0 is a route learned from the dynamic routing protocol that will never be placed in a routing table 0.0.0.0/0 is a default route. It has top priority, and the router will use it to route packets even if it has a more specific route to the destination

0.0.0.0/0 is a default route. The router uses it to route packets if it doesn't have a more specific route to the destination

When is dynamic routing protocol preferred over static routes? The size of the network is not important when choosing a dynamic routing protocol over a static route Dynamic routing protocols are better in large environments where there are many networks and devices Static routing protocols have complex configurations Dynamic routing protocols are better in smaller environments because they are simple to configure and maintain
