CCNA2 Chapters 1-11

A new network administrator is given the task of selecting an appropriate dynamic routing protocol for a software development company. The company has over 100 routers, uses CIDR and VLSM, requires fast convergence, and uses both Cisco and non-Cisco equipment. Which routing protocol is appropriate for this company?

What two events will cause a link state router to send LSPs to all neighbors? (Choose two.)

What is the final step in the link state routing process?

Refer to the exhibit. What does JAX do with link-state packets from ORL?

What two statements correctly describe the link state routing process? (Choose two.)

Which database or table must be identical on all link-state routers within an area in order to construct an accurate SPF tree?

Refer to the exhibit. Which statement correctly describes the path traffic would take from the 10.0.0.0/24 network to the 192.168.1.0/24 network if a link-state routing protocol was in use?

What feature do modern link-state protocols provide to minimizeprocessing and memory requirements?

What speeds up convergence in a network using link-state routing?

Which algorithm is run by link-state routing protocols to calculate the shortest path to destination networks?

What are some of the advantages of using a link-state routing protocol instead of a distance vector routing protocol? (Choose two.)

Refer to the exhibit. If all routers and interfaces are configured to use a link-state routing protocol, from which routers will router D receive hello packets?

Which two routing protocols use Dijkstra’s shortest path first algorithm? (Choose two.)

When are link-state packets sent to neighbors?

What are two advantages of using a link-state routing protocol instead of a distance vector routing protocol? (Choose two.)

To achieve network convergence, what three steps does each link state router take? (Choose three.)

Refer to the exhibit. All routers are running OSPF. What cost would JAX put in its routing table for the 10.0.0.0/24 network?

Refer to the exhibit. Router1 and Router2 are running OSPF. The show ip ospf neighbor command reveals no neighbors. What is a possible cause?

A fully converged five router OSPF network has been running successfully for several weeks. All configurations have been saved and no static routes are used. If one router looses power and reboots, what information will be in its routing table after the configuration file is loaded but before OSPF has converged?

Refer to the exhibit. What configuration statements would give the results that are shown in the output of the show ip protocols command?

Refer to the exhibit. When OSPF is operational in the exhibited network, what neighbor relationship is developed between Router1 and Router2?

What does OSPF use to calculate the cost to a destination network?

Refer to the exhibit. The routers in the exhibit are using default OSPF configuration settings to advertise all attached networks. If all of the routers start at the same time, what will be the result of the DR and BDR elections for this single area OSPF network? (Choose three.)

What does OSPF use to reduce the number of exchanges of routing information in networks where large numbers of neighbors are present? (Choose two.)

Refer to the exhibit. All routers have been configured with the interface priorities that are shown. All routers were restarted simultaneously. The results of the DR/BDR election are shown. What can be concluded about this network?

Refer to the exhibit. Router A is correctly configured for OSPF. Which OSPF configuration statement or set of statements was entered for router B to generate the exhibited routing table?

Refer to the exhibit. Assuming that the routers have default interface OSPF priorities and no configured loopback interfaces, what two roles will router B play on each network segment? (Choose two.)

Refer to the exhibit. Routers A, B, C, and D are all running OSPF with default router IDs and OSPF interface priorities. Loopback interfaces are not configured and all interfaces are operational. Router D is the DR and router C is the BDR. What happens immediately after the following commands are entered on router A? 

What range of networks will be advertised in the OSPF updates by the command Router1(config-router)# network 192.168.0.0 0.0.15.255 area 100?

Refer to the exhibit. RouterA, RouterB, and RouterC in the diagram are running OSPF on their Ethernet interfaces. Router D was just added to the network. Routers are configured with the loopback interfaces (Lo 0) that are shown in the exhibit. What happens to the OSPF DR/BDR after RouterD is added to the network?

Refer to the exhibit. How many OSPF adjacencies must be formed to build the complete topology if a DR or BDR were not elected in this OSPF network?

What is the default administrative distance for OSPF?

Refer to the exhibit. Which command sequence on RouterB will redistribute a gateway of last resort to the other routers in OSPF area 0?

Which two statements describe the use of OSPF DR/BDR elections? (Choose two.)

Refer to the exhibit. What does the “2″ stand for in the router ospf 2 statement?

Refer to the exhibit. The network administrator wants to set the router ID of Router1 to 192.168.100.1. What steps can the administrator take to accomplish this?

Refer to the exhibit. What must be received between neighbors to prevent the dead time that is shown in the exhibit from reaching zero?

Refer to the exhibit. What does the “O*E2″ from the “O*E2 0.0.0.0/0 [110/1] via 192.168.1.1, 00:05:34, Serial0/0″ line represent?

Refer to the exhibit. Which network command or set of commands will cause OSPF to be enabled for any R1 interface connected to the exhibited subnets?

Refer to the exhibit. What is the cost of the route to the 10.0.0.0 network?
