1. Which of the following correctly states one of the routing principles? (Points : 5) If one router has certain information in its routing table, all adjacent routers have the same information. Routing information about a path from one network to another implies routing information about the reverse or return path. Every router makes its routing decisions alone, based on the information it has in its own routing table. Every router makes its routing decisions based on the information it has in its own routing table and its neighbor routing tables.
Every router makes its routing decisions alone, based on the information it has in its own routing table.
2. (TCO 2) If you are configuring static routes using next-hop addresses, which of the following is true? (Points : 5) Routers cannot use more than one static route with a next-hop address. When the router identifies that a packet is destined for a route associated with a next-hop address in the routing table, the router requires no further information and can immediately forward the packet. Routers configured with the static route using a next-hop address must either have the exit interface listed in the route, or have another route with the network of the next hop and an associated exit interface. Routes associated with a next-hop address are more efficient than routes going to exit interfaces.
Routers configured with the static route using a next-hop address must either have the exit interface listed in the route, or have another route with the network of the next hop and an associated exit interface
3. (TCO 4) Which of the following technologies can be used to prevent routing loops in distance-vector routing protocols? (Points : 5) Spanning Tree Protocol Shortest path first tree Hold-down timers None of the above
Hold-down timers
4. (TCO 4) What is the default number of equal-cost paths that a dynamic routing protocol can use for load balancing? (Points : 5) Two Three Four Six
Four
5. (TCO 4) Which of the following can be used to avoid a count-to-infinity loop? (Points : 5) Split horizon Route poisoning Hold-down timers Triggered updates
Split horizon
6. (TCO 4) What is a discontinuous network? (Points : 5) A classful network that has subnets separated by one or more different major networks A classful network with VLSM A network subnetted with a mask less than the classful mask None of the above
A classful network that has subnets separated by one or more different major networks
7. (TCO 5) During the route lookup process, what determines the preferred route? (Points : 5) The ultimate route The longest match of leftmost bits The shortest prefix length The first route that resolves to an exit interface
The longest match of leftmost bits
8. (TCO 3) Which of the following is a false statement about RIPv1 based on the fact that it is a classful routing protocol? (Points : 5) RIPv1 does not send subnet mask information in its update. RIPv1 networks cannot be discontiguous. RIPv1 is a distance-vector routing protocol. RIPv1 uses cost as its only metric for path selection.
RIPv1 does not send subnet mask information in its update.
9. (TCO 5) Which of the following routing protocols supports VLSM? (Points : 5) RIPv1 RIPv2 Both RIPv1 and RIPv2 Neither RIPv1 nor RIPv2
RIP2
10. (TCO 3) Which of the following would be a boundary router in RIP? (Points : 5) If it is on the edge of an autonomous system If a router has multiple interfaces in more than one major classful network If it runs both RIP and EIGRP at the same time If it is configured to be a boundary router by an administrator
If a router has multiple interfaces in more than one major classful network
11. (TCO 6) Which of the following commands correctly specifies that network 10.0.0.0 is directly connected to a router that is running EIGRP? (Points : 5) Router(config)#network 10.0.0.0 Router(config)#router eigrp 10.0.0.0 Router(config-router)#network 10.0.0.0 Router(config-router)#router eigrp 10.0.0.0
Router(config-router)#network 10.0.0.0
12. (TCO 4) Which command will configure EIGRP on a router? (Points : 5) Route IP Network 192.1.0.0 Config EIGRP Router EIGRP 100
Router(config)#router eigrp AS
Router(config-router)#network XXX.XXX.XXX.XXX
13. (TCO 7) On a router running OSPF, what is the purpose of entering the “bandwidth 56” command on a serial interface? (Points : 5) Changes the cost value Functions only as a description Changes the throughput of the interface to 56 Kbps Is necessary for the DUAL algorithm
Changes the cost value Functions only as a description
