Ccna certification Practice Tests

 117.  A.  The IP address of 194.22.34.54/28 belongs to the network of 194.22.34.48/28. All 

other answers are incorrect.

 118.  C.  When entering IPv6 routes. you must use the command 

ipv6 route. It is then 

followed by the IPv6 prefix and mask and then the gateway. The default route would be 

ipv6 route ::/0 serial 0/0. The command ip route 0.0.0.0 0.0.0.0 serial 

0/0 is incorrect because it’s specific to IPv4. The command ipv6 route 0.0.0.0 

0.0.0.0 serial 0/0 is incorrect because it’s a mix of IPv6 and IPv4. The command ip 

route ::/0 serial 0/0 is incorrect because it’s a mixture of IPv4 and IPv6.

 119.  B.  When configuring an IPv6 route, you use the 

ipv6 route command. You then must 

specify the network and mask using CIDR notation. Last, you specify the exit interface or 

next hop of 

serial 0/0/0. The complete command will be ipv6 route fc00:0:0:1/64 

serial 0/0/0. The command ip route fc00:0:0:1 serial 0/0/0 is incorrect because 

it’s a mixture of IPv4 and IPv6. The command 

ip route fc00:0:0:1/64 serial 

0/0 is incorrect because it’s a mixture of IPv4 and IPv6. The command ipv6 route 

fc00:0:0:1 serial 0/0/0 is incorrect because it is missing the subnet mask.

 120.  A.  The packet will be routed to the IP address of 192.168.4.2. This will occur because the 

administrative distance is lower than the route for the gateway of 192.168.4.5. Interface 

Serial 0/0/1 and Interface Serial 0/2/0 will not be used because no matching route exists in 

the route table.

 121.  D.  The command 

no switchport does the opposite of configuring a port as a switch 

port. It turns the port into a routed interface in which an IP address can be configured. A 

Switched Virtual Interface (SVI) is created when a VLAN interface is created and it is not 

related to a switch port. An access port is configured with the 

switchport mode access 

command. A trunk port is configured with the 

switchport mode trunk command.

 122.  B.  Router on a stick (ROAS) is created by configuring a trunk between the switch and the 

router. ROAS will receive tagged frames and route them, then send them back down the 

interface to the respective connected VLAN. Although you could purchase a router with 

additional interfaces, this would not be the most efficient method of completing the task. 

Configuring a dynamic routing protocol will not accomplish this task.

 123. C. The 

ip routing command must be entered in global config. When this command 

is entered, a routing table will be created and populated. The command 

routing is 

incorrect. The command 

ip router is incorrect. The command ip route is incorrect.
