Question 1

Routing Protocol Category: IGP

Answer 1

Interior Gateway Protocols: A routing protocol that was designed and intended for use inside a single autonomous system (AS)

Routing Protocol Category: EGP

Answer 2

Exterior Gateway Protocols: A routing protocol that was designed and intended for use between different autonomous systems

Question 3

IP IGP Metric: RIP-1 RIP-2

Answer 3

Hop count; The number of routers (hops) between a router and the destination subnet.

Question 4

IP IGP Metric: OSPF

Answer 4

Cost; The sum of all interface cost settings for all links in a route; with the cost defaulting to be based on interface bandwidth.
