Chapter 9

1. A The router knows only about directly connected routes by default.

2. D The easiest way is to add static routes to each router. Although you could add routing protocols such as OSPF or RIPv2 to create dynamic routes, it’s much easier to just add static routes if you have only two routers and three subnets.

3. False Routers use the least cost path based on the metric to determine the best path.

4. Routing table A router stores all known routes in a routing table.

5. A, B, C Routing protocols allow clients to learn routes from each other dynamically. Common routing protocols on internal networks are RIPv2 and OSPF. ARP translates IP addresses to MAC addresses.

6. False Windows Server 2008 supports RIPv2 but not OSPF.

7. B A DHCP relay agent can be added to relay DHCP BootP broadcasts through routers that are not RFC 1542 compliant. RFC 1542-compliant routers can forward DHCP and BootP broadcasts. Adding another DHCP server would be an expensive solution and would work only if you had only two subnets connected. If you used this solution, you would need to add DHCP servers for every subnet.
