A. The OSPF area is not configured properly.
B. The priority on R1 should be set higher.
C. The cost on R1 should be set higher.
D. The hello and dead timers are not configured properly.
E. A backup designated router needs to be added to the network.
F. The OSPF process ID numbers must match.
Q77. Which two commands will display the current IP address and basic Layer 1 and 2 status of an interface? (Choose two.)
A. router#show version
B. router#show ip interface
C. router#show protocols
D. router#show controllers
E. router#show running-config
Q78. What is the subnet broadcast address of the LAN connected to Router1?
Q79. Refer to the exhibit.
The output is from a router in a large enterprise. From the output, determine the role of the router.
A. A Core router.
B. The HQ Internet gateway router.
C. The WAN router at the central site.
D. Remote stub router at a remote site.
Q80. Refer to the exhibit.
The network administrator is testing connectivity from the branch router to the newly installed application server. What is the most likely reason for the first ping having a success rate of only 60 percent?
A. The network is likely to be congested, with the result that packets are being intermittently dropped.
B. The branch router had to resolve the application server MAC address.
C. There is a short delay while NAT translates the server IP address.
D. A routing table lookup delayed forwarding on the first two ping packets.
E. The branch router LAN interface should be upgraded to FastEthernet.

Q81. Refer to the exhibit.
A network has been planned as shown. Which three statements accurately describe the areas and devices in the network plan? (Choose three.)
A. Network Device A is a switch.
B. Network Device B is a switch.
C. Network Device A is a hub.
D. Network Device B is a hub.
E. Area 1 contains a Layer 2 device.
F. Area 2 contains a Layer 2 device.
Q82. Which of the following IP addresses are valid Class B host addresses if a default Class B
mask is in use? (Choose two.)
Q83. Which of the following describe the process identifier that is used to run OSPF on a router? (Choose two)
A. It is locally significant.
B. It is globally significant.
C. It is needed to identify a unique instance of an OSPF database.
D. It is an optional parameter required only if multiple OSPF processes are running on the router.
E. All routers in the same OSPF area must have the same process ID if they are to exchange routing information.
Q84. What is the purpose of the switchport command?
Switch(config-if)# switchport port-security maximum 1 Switch(config-if)# switchport port-security mac-address 0018.DE8B.4BF8
A. It ensures that only the device with the MAC address 0018.DE8B.4BF8 will be able to connect to the port that is being configured.
B. It informs the switch that traffic destined for MAC address 0018.DE8B.4BF8 should only be sent to the port that is being configured.
C. It will act like an access list and the port will filter packets that have a source or destination MAC of 0018.DE8B.4BF8.
D. The switch will shut down the port of any traffic with source MAC address of 0018.DE8B.4BF8.
Q85. Refer to the exhibit.
Given the output for this command, if the router ID has not been manually set, what router ID will OSPF use for this router?

R1 and R2?
A. Configure the router with the cdp enable command.
B. Enter no shutdown commands on the R1 and R2 fa0/1 interfaces.
C. Configure IP addressing and no shutdown commands on both the R1 and R2 fa0/1 interfaces.
D. Configure IP addressing and no shutdown commands on either of the R1 or R2 fa0/1 interfaces.

C. R1(config)# interface fastethernet0/0 R1(config-if)# ip nat inside
D. R1(config)# interface fastethernet0/0 R1(config-if)# ip nat outside
E. R1(config)# interface serial0/1 R1(config-if)# ip nat outside source pool 126.96.36.199 255.255.255.252
F. R1(config)# interface fastethernet0/0 R1(config-if)# ip nat inside source 10.10.0.0 255.255.255.0
