1. IP Addresses are/do: (check all that apply) a. Exist in the Data Link Layer b. Physical addresses c. Connect LANs to each other d. Grouped to classes and/or sub-nets 2. Each LAN has a Network IP address a. True b. False 3. An IP Mask is used to separate a Network address from a Node/Host address a. True b. False 4. IP address classes A,B,C, do not have a range of private reserved addresses a. True b. False 5. IP addresses of all classes can be further divided into "subnets" to more efficiently use the IP address space a. True b. False 6. Role of a router(s) is to: (check all that apply) a. Translate illegal private IP addresses to legal external ones b. Forward IP addressed packets from source to destination c. Notify all other network routers of its network connections 7. Program that routers use to forward data packets is called a Switching Algorithm a. True b. False 8. Which Routing Algorithm can adopt to a changing network topology and is suitable for large networks a. Static b. Dynamic 9. Routing Information Protocol (RIP) is part of a. Link State b. Distance-Vector 10. Open Shortest Path First (OSPF) is a part of: a. Link state b. Distance-Vector 11. Which routing protocol limits number of hops to 15 a. RIP b. OSPF 12. TCP and UDP protocols are part of which layer on the OSI network model? a. Layer 3 b. Layer 4 c. Layer 5 13. Which protocol establishes a connection between end stations before transmission? a. TCP b. UDP 14. Which protocol monitors and maintains the state of endto-end session throughout data transmission? a. TCP b. UDP 15. Reliable data transfer service is enabled by acknowledgements of each transmission between end stations a. True b. False 16. TCP protocol is considered (check all that apply) a. Connection oriented b. Connectionless c. Stateful d. Stateless e. Reliable f. Unreliable 17. Which protocol offers data flow/congestion schemes a. TCP b. UDP 18. If the physical layer between end stations is of high quality and reliable (i.e. LAN or fiber optic long haul link) and speed of transmission is important which protocol would you choose a. TCP b. UDP 19. If you know that higher layer services manage their own reliability and connections which protocol would you choose? a. TCP b. UDP 20. If you know that physical layer includes aging or very diverse links of varying bandwidth capabilities and reliable end user services are important, which protocol would you choose? a. TCP b. UDP 21.
