• The router will prompt the user for a response to enter setup mode.
• The startup sequence will halt until a valid configuration file is acquired.
• The router will generate a default configuration file based on the last valid configuration.
• The router will monitor local traffic to determine routing protocol configuration requirements.

2. 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?

• The destination networks do not exist.
• The IP addresses on the router interfaces must be configured as network addresses and not host addresses.
• The interfaces must be enabled with the no shutdown command.
• Each interface must be configured with the clock rate command.

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

• This router only has two interfaces.
• The router interfaces are not operational yet.
• This router is configured to forward packets to remote networks.
• The FastEthernet0/0 and Serial0/0/0 interfaces of this router were configured with an IP address and the no shutdown command.
• An IP packet received by this router with a destination address of 198.18.9.1 will be forwarded out of the Serial0/0/0 interface.

1. Refer to the exhibit. When Router D is configured to use a link-state routing protocol and is added to the network, what is the first thing that it does to begin learning the network topology?

• It sends LSP packets to Routers B and C.
• It sends LSP packets to all routers in the network.
• It sends Hello packets to all routers in the network.
• It sends information about its directly connected neighbors to Routers A and E.
• It sends information about its directly connected neighbors to all routers in the network.
• It learns about its directly connected networks when its interfaces reach the up state.

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

• 30 second timer expires
• whenever the network topology changes
• immediately after the Bellman-Ford algorithm has run
• immediately after the DUAL FSM has built the topology database
• upon initial startup of router or routing protocol

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

• successors are placed into the routing table
• SPF computes best path to each destination network
• LSPs are flooded to all neighbors to converge the network
• DUAL algorithm is run to find best path to destination networks

1. 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?

• an internal type 2 OSPF route.
• an external OSPF route at least two hops away.
• an external OSPF route from two different sources.
• an external OSPF route that will not increment in cost.
• a default route.
• The route was distributed into OSPF from a type 2 router.

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

• 2
• 110
• 1786
• 1.544

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

• area id
• K-values
• metric value
• hello interval
• network type
• interface type

1. Which two statements correctly describe the concepts of administrative distance and metric? (Choose two.)

• Administrative distance refers to the trustworthiness of a particular route.
• A router first installs routes with higher administrative distances.
• The value of the administrative distance can not be altered by the network administrator.
• Routes with the smallest metric to a destination indicate the best path.
• The metric is always determined based on hop count.
• The metric varies depending which Layer 3 protocol is being routed, such as IP or IPX.

2. Refer to the exhibit. Which statement correctly describes how R1 will determine the best path to R2?

• R1 will install a RIP route using network A in its routing table because the administrative distance of RIP is higher than EIGRP.
• R1 will install a RIP route using network A in its routing table because the path cost from RIP is lower than EIGRP.
• R1 will install an EIGRP route using network B in its routing table because the administrative distance of EIGRP is lower than RIP.
• R1 will install an EIGRP route using network B in its routing table because the path cost from EIGRP is lower than RIP.
• R1 will install an EIGRP route and a RIP route in its routing table and load balance between them.

3. Which two statements are true regarding classless routing protocols? (Choose two.)

• sends subnet mask information in routing updates
• sends complete routing table update to all neighbors
• is supported by RIP version 1
• allows for use of both 192.168.1.0/30 and 192.168.1.16/28 subnets in the same topology
• reduces the amount of address space available in an organization

1. Refer to the exhibit. What command will place the router into the correct mode to configure an appropriate interface to connect to a LAN?

• UBAMA# configure terminal
• UBAMA(config)# line vty 0 4
• UBAMA(config)# line console 0
• UBAMA(config)# interface Serial 0/0/0
• UBAMA(config)# interface FastEthernet 0/1

2. In a Cisco router, when do changes made to the running-configuration take effect?

• after a system restart
• as the commands are entered
• when logging off the system
• when the configuration is saved to the startup-configuration

3. Refer to the exhibit. A technician applies the configuration in the exhibit to a clean router. To verify the configuration, the technician issues the show running-config command in the CLI session with the router. What lines should the technician expect to see in the router output from the show running-config command?
