packet that needs to be forwarded arrives on an interface of a router. In order for a router to route data, what must that router determine? (Select the best answer)
1. The route age of the next-hop device
2. The subnet mask of the source network
3. The cost metric of the path of the destination
4. The outbound interface of the best path to the destination
What is the purpose of configuring a router with the "IP Helper address" command?
1. IP Helper is used to direct BOOTP clients to a BOOTP server.
2. IP Helper is used to direct BOOTP clients to a BOOTP server.
3. IP Helper is used to allow IPX clients to communicate with IP-based servers.
4. IP Helper is used to accommodate compatibility routers using different IP routing protocols.
You are determining the routing protocol to use throughout your network. In doing this you compare the advantages of classless and classful protocols. Which of the following statements are true regarding classless routing protocols
1. A default gateway is required.
2. Variable-length subnet masks are not supported.
3. Routers are automatically summarized to class boundaries.
4. Networks with different subnet masks can exist in the same address class.
You wish to use a classless IP routing protocol within your network. Which of the following classless routing protocols could you use? (Select all that apply)
1. IS-IS
2. IGRP
3. RIPv1
4. OSPF
When you execute the "ip helper-address" command on a router, which three UDP ports get enabled automatically by default? (Select three)
1. 53 (DNS)
2. 69 (TFTP)
3. 515 (LPR)
4. 49 (TACACS)
there is a route to the subnet 190.10.1.0/25 learned via RIP and a route to the subnet 190.10.1.0/24 learned via STATIC, which route would be preferred to reach the destination address 190.10.1.125?
1. The 190.10.1.0/25 route learned via RIP will be used because its prefix has the longest match.
2. RIP has an administrative distance of 120, and static routes have an administrative distance of 1, so the static route would be preferred.
3. The static route to 190.10.1.0/24 will be preferred because static routes have an administrative distance of 0 and the static route looks as though it is directly connected
4. A show ip route to the destination will show that the destination is learned from both RIP and the static route, so the traffic to 190.10.1.1.125 will be load balanced between the two paths.
