In traditional non software-defined network consisting of a network of switches, suppose OSPF is being used as the routing protocol. In this context which among the following is true. a. All the switches execute OSPF distributively b. Only one switch executes OSPF c. No switch executes OSPF d. All of these are true

Select all statement(s) that are true.(a) A link state protocol floods information to each AS router about the state of all routers in the AS.(b) A link state protocol is an IGP routing protocol used in packet switching networks.(c) OSPF uses a Link State Advertisement (LSA) message to distribute changes or initial startup information to other routers.

An OSPF routing protocol configured on router knows each node within its network domain and also the entire topology of that network domain.Question 2Answera.Falseb.True

A) OSPF is based on distance-vector routing protocol.(B) Both link-state and distance-vector routing are based on the least cost goal.(C) BGP4 is based on the path-vector algorithm.(D) The three-node instability can be avoided using split horizon combined with poison reverse.(E) RIP is based on link state algorithm.

In SDN, the Operating System (OS) is separated (i.e not strongly coupled) from the physical hardware for each switch. a. True b. False

Which statement is correct about network protocols?
