CCNA2 Chapters 1-11

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?

What three parameters must be indentical between OSPF routers in order to form an adjacency? (Choose three.)

Refer to the exhibit. The network administrator has configured the router with the interface IP addresses shown for the directly connected networks. Pings from the router to hosts on the connected networks or pings between router interfaces are not working. What is the most likely problem?

Refer to the exhibit. What can be concluded from the routing table output in the exhibit? (Choose two.)

Refer to the exhibit. The frame shown in the exhibit was received by the router. The router interfaces are operational. How will the router process this frame? (Choose two.)

Passwords can be used to restrict access to all or parts of the Cisco IOS. Select the modes and interfaces that can be protected with passwords. (Choose three.)

Which two statements correctly describe the components of a router? (Choose two.)

Refer to the exhibit. After host 2 is connected to the switch on the LAN, host 2 is unable to communicate with host 1. What is the cause of this problem?

Which are functions of a router? (Choose three.)

Refer to the exhibit. All routers have a route in its routing table to each network that is shown in the exhibit. Default routes have not been issued on these routers. What can be concluded about how packets are forwarded in this network? (Choose two.)

The serial connection shown in the graphic needs to be configured. Which configuration commands must be made on the Sydney router to establish connectivity with the Melbourne site? (Choose three.)

Refer to the exhibit. What can be concluded from the output of the running-configuration of a router?

Refer to the exhibit. Host A pings host B. When R4 accepts the ping into the Ethernet interface, what two pieces of header information are included? (Choose two.)

What is the outcome of entering these commands?
R1(config)# line vty 0 4 R1(config-line)# password check123
R1(config-line)# login

Which of the following is the correct flow of routines for a router startup?

What three processes does a router execute when it receives a packet from one network that is destined for another network? (Choose three.)
