 56.  A.  The command 

show ipv6 route will display only the entries in the routing table for 

IPv6. The command 

show ip route will only display the entries in the routing table for 

IPv4. The command 

show ipv6 route summary is incorrect. The command show ipv6 

route brief is incorrect.

 57.  C.  You will need two route statements, one on each router. Each route should point to 

the far side network through the serial interface. Since the IP address is an IPv6 address, 

the easier way to configure the routes is to direct the packets to the exit interface of Serial 

0/3/0. All of the other options are incorrect because the commands specify either the 

wrong protocol or the wrong routes.

 58.  B.  The command 

show ipv6 route connected will display only the directly connected 

routes on the router. The command 

show ipv6 interface summary is incorrect. The 

command 

show ipv6 interface brief is incorrect. The command show ipv6 summary 

is incorrect.

 59.  C.  The route statement 

ipv6 route ::/0 serial 0/3/0 will route any network 

that is unknown by Router B to Router A via the exit interface of Serial 0/3/0. The 

command 

ipv6 route 0.0.0.0 0.0.0.0 serial 0/3/0 is incorrect because it mixes 

IPv4-style IP addresses and the 

ipv6 route command. The command ipv6 route 

2002:ea34:4520:3412::/64 serial 0/3/0 is incorrect. The command ipv6 route 

::/0 2001:db8:1500::/64 eui is incorrect.

 60.  D.  You will need two route statements, one on each router. Each route points to the 

far side network through the gateway in the ff80::/64 network. Router A has a gateway 

of ff80::ff:f200:2/64 to the 2001:db8:4:/64 network, and Router B has a gateway of 

ff80::ff:f200:1/64 to the 2001:db8:400/64 network. All other answers are incorrect 

because the commands specify either the wrong protocol or the wrong routes.

 61. B. The 

ping command will allow basic connectivity testing at layer 3. The command 

show ip route is incorrect. The command pathping 192.168.4.1 is incorrect; the 

pathping command is only available on Windows operating systems. The command ip 

ping 192.168.4.1 is incorrect; the ip command does not need to be specified.

 62.  D.  The command 

traceroute will allow you to verify the path on which a packet 

gets routed. The command 

show ip route is incorrect. The command tracert 

192.168.7.56 is incorrect; the tracert command is only available on Windows 

operating systems. The command 

pathping 192.168.7.56 is incorrect; the pathping 

command is only available on Windows operating systems.

 63.  C.  Both routers have passive interfaces for OSPF. In order to fix this, the command 

no 

passive-interface serial 0/0 would need to be entered. This command would need 

to be configured in the OSPF router process. The routers are within the same network 

with a common serial line connecting the routers. The process IDs do not matter and are 

locally significant to the routers. The hello/dead intervals for both routers match each 

other.
