3. To connect four end nodes in a mesh technology, three transmission lines and six connections per node are required.

4. Mesh topology is practical for all but very small networks.

5. In a physical delivery system, the central nodes are transfer points located at or near the junction of major roadways or air routes.

6. The characteristics differentiating the physical topologies include the length and routing of network cable, type of node connections, data transfer performance, susceptibility of the network to failure, and cost.

7. Networks using bus and ring physical topologies are commonly used today.

8. Star topologies now dominate physical network topology for wired networks.

9. The OSI model predates the TCP/IP model by almost a decade.

10. The 32-bit addresses for an IP node are defined in Internet Protocol version 6 (IPv6).

11. Internet Protocol version 6 (IPv6) is an updated version of IPv4 defined in the late 1990s and first deployed in the mid-2000s.

12. Guaranteeing service quality is a simple matter in most IP networks.

13. RARP converts IP addresses to physical network addresses.

14. The 802.1 and 802.2 standards correspond roughly to the OSI Data Link layer.

20. 10 Gigabit Ethernet is based on the 802.3ae (2002) and the 802.3ak (2004) standards.
