| 1: | What is connectionless data networking? |
| 2: | Why is routing needed in a connectionless networking environment? List two means by which routers obtain information for routing packets toward their destinations. |
| 3: | What is the difference between functionalities of Interior Gateway Protocols (IGPs) versus exterior gateway protocols (EGPs)? |
| 4: | List the two main groups of IP routing protocols based on the method of operation and routing algorithm. Also, list two examples of each type. |
| 5: | Briefly describe the operation of link-state routing protocols. |
| 6: | What is the key difference between classless and classful routing protocols? Give an example of each. |
| 7: | What is the use of routing protocol administrative distances on Cisco routers? |
| 8: | What are the values of administrative distance of IS-IS and OSPF, respectively? |
| 9: | If a router is running both OSPF and IS-IS protocols and has the same route from each of them, which protocol's information will be used in the IP routing table? |
