Ch 2 Q 24
Do not use abbreviations.What is the missing command on S1?
Correct Answer: ip address 192.168.99.2 255.255.255.0
The ip address 192.168.99.2 255.255.255.0 command is missing on interface vlan 99, the management
VLAN.
CH 3 Q 24
Which PCs will receive the broadcast sent by PC-C?
PC-A, PC-B
PC-D, PC-E
PC-A, PC-B, PC-E
PC-A, PC-B, PC-D, PC-E
PC-A, PC-B, PC-D, PC-E, PC-F
Only hosts in the same VLAN as PC-C (VLAN 20) will receive the broadcast. The trunk links will carry
the broadcast to ALS2 where it will be send to PC-D and PC-E, which are also in VLAN 20. PC-A, PC-B,
and PC-F are not in the same VLAN as PC-C. This information can be verified by issuing the show vlan
and show interfaces trunk commands.
CH5 Q 23
Which command is missing on the Layer 3 switch to restore the full connectivity between PC1 and the web server?
Correct Answer: ip address 192.168.20.1 255.255.255.0
On the Layer 3 switch, an SVI has to be explicitly created for each VLAN. PC1 belongs to VLAN 10,
which is already created on the Layer 3 switch and with an IP address assigned. The web server belongs to
VLAN 20. The interface vlan 20 command was already entered on the Layer 3 switch, but with no IP
address assigned to it. So the ip address 192.168.20.1 255.255.255.0 command has to be entered in the
interface vlan 20 interface mode. To test the connectivity between the PC1 and the web server, access PC1,
select the Desktop tab, click on the Web Browser application and enter on the URL box
"www.webserver.com". A message "Congratulations! You've got it!" will be displayed.
CH 6 Q 21
What is the name of the web server that is displayed in the webpage?
Main-Webserver
WWW-Server
Webserver10
MNSRV
Static routes can be configured by using the syntax router(config)# ip route prefix mask {ip-address |
exit-intf}. In this case, the command to be issued would be router(config)# ip route 192.168.3.0
255.255.255.0 192.168.2.2.
CH 6 Q 22
What IPv6 static route can be configured on router R1 to make a fully converged network?
ipv6 route 2001:db8:10:12::/64 S0/0/1
ipv6 route 2001:db8:10:12::/64 S0/0/0
ipv6 route 2001:db8:10:12::/64 2001:db8:10:12::1
ipv6 route 2001:db8:10:12::/64 2001:db8:32:77::1
To reach the remote network, R1 will need a static route with a destination IPv6 address of
2001:db8:10:12::/64 and an exit interface of S0/0/1. The correct static route configuration will be as
follows: ipv6 route 2001:db8:10:12::/64 S0/0/1.
CH 8 Q 24
What message is displayed on www.ciscoville.com?
Finished!
Completion!
Success!
Converged!
The correct configuration on R1 is:
router ospf 10
network 192.168.2.0 0.0.0.255 area 0
network 10.0.10.0 0.0.0.3 area 0
The correct configuration on R2 is:
router ospf 10
network 10.0.10.0 0.0.0.3 area 0
network 10.0.10.4 0.0.0.3 area 0
network 172.16.5.0 0.0.0.255 area 0
The PT initialization was skipped. You will not be able to view the PT activity.
Open the PT Activity. Perform the tasks in the activity instructions and then answer the question.
Why is the ACL not working?
The interface has not been enabled.
The ACL is applied in the wrong direction.
The ACL is missing a deny ip any any ACE.
The ACL is applied to the wrong interface.
The access-list 105 command or commands are incorrect.
The ACL is currently applied to the unused Fa0/0 interface. The server is attached to the same network to
which the R1 Fa0/1 interface is attached. The ACL should be applied to this interface to protect the server.
CH 10 Q 23
The PT initialization was skipped. You will not be able to view the PT activity.
Open the PT Activity. Perform the tasks in the activity instructions and then answer the question.
How many IP addresses has the DHCP server leased and what is the number of DHCP pools configured? (Choose two.)
three leases
six pools
five leases
one pool
two pools
seven leases
The show ip dhcp binding command will display that the DHCP server has leased three IP addresses. The
show running-config command will show that there is only one DHCP pool that is configured.
CH 11 Q 23
What problem is causing PC-A to be unable to communicate with the Internet?
The static route should not reference the interface, but the outside address instead.
This router should be configured to use static NAT instead of PAT.
The ip nat inside source command refers to the wrong interface.
The access list used in the NAT process is referencing the wrong subnet.
The NAT interfaces are not correctly assigned.
The output of show ip nat statistics shows that the inside interface is FastEthernet0/0 but that no interface
has been designated as the outside interface. This can be fixed by adding the command ip nat outside to
interface Serial0/0/0.
