Q4. Refer to the exhibit.
All devices attached to the network are shown. Which number of collision domains are present in this network?
A. 9
B. 3
C. 6
D. 2
E. 15
Answer: E
Q5. Which IPv6 address is the all-router multicast group?
A. FF02::1
B. FF02::2
C. FF02::3
D. FF02::4
Answer: B
Explanation:
Well-known IPv6 multicast addresses:
Address Description ff02::1
All nodes on the local network segment
ff02::2
All routers on the local network segment
Q6. Refer to the exhibit.
The network shown in the diagram is experiencing connectivity problems. Which of the following will correct the problems? (Choose two.)
A. Configure the gateway on Host A as 10.1.1.1.
B. Configure the gateway on Host B as 10.1.2.254.
C. Configure the IP address of Host A as 10.1.2.2.
D. Configure the IP address of Host B as 10.1.2.2.
E. Configure the masks on both hosts to be 255.255.255.224.
F. Configure the masks on both hosts to be 255.255.255.240.
Answer: B,D
Explanation:
The switch 1 is configured with two VLANs: VLAN1 and VLAN2. The IP information of member Host A in VLAN1 is as follows: Address : 10.1.1.126
Mask : 255.255.255.0
Gateway : 10.1.1.254
The IP information of member Host B in VLAN2 is as follows: Address : 10.1.1.12
Mask : 255.255.255.0
Gateway : 10.1.1.254
The configuration of sub-interface on router 2 is as follows: Fa0/0.1 -- 10.1.1.254/24 VLAN1
Fa0/0.2 -- 10.1.2.254/24 VLAN2
It is obvious that the configurations of the gateways of members in VLAN2 and the associated network segments are wrong. The layer3 addressing information of Host B should be modified as follows:
Address : 10.1.2.X Mask : 255.255.255.0
Q7. An administrator is trying to ping and telnet from SwitchC to RouterC with the results shown below.
Click the console connected to RouterC and issue the appropriate commands to answer the questions.
What would be the effect of issuing the commandip access-group 115 inon the s0/0/1 interface?
A. No host could connect to RouterC through s0/0/1.
B. Telnet and ping would work but routing updates would fail.
C. FTP, FTP-DATA, echo, and www would work but telnet would fail.
D. Only traffic from the 10.4.4.0 network would pass through the interface.
Answer: A
Explanation:
First letu2021s see what was configured on interface S0/0/1:
Q8. Which two of these statements are true of IPv6 address representation? (Choose two.)
A. There are four types of IPv6 addresses: unicast, multicast, anycast, and broadcast.
B. A single interface may be assigned multiple IPv6 addresses of any type.
C. Every IPv6 interface contains at least one loopback address.
D. The first 64 bits represent the dynamically created interface ID.
E. Leading zeros in an IPv6 16 bit hexadecimal field are mandatory.
Answer: B,C
Explanation:
u2711 A single interface may be assigned multiple addresses of any type (unicast, anycast, multicast).
u2711 Every IPv6-enabled interface must contain at least one loopback and one link-local
address.
u2711 Optionally, every interface can have multiple unique local and global addresses.

Q9. What is the default Syslog facility level?
A. local4
B. local5
C. local6
D. local7
Answer: D
Explanation:
By default, Cisco IOS devices, CatOS switches, and VPN 3000 Concentrators use facility local7 while Cisco PIX Firewalls use local4 to send syslog messages. Moreover, most Cisco devices provide options to change the facility level from their default value.
Reference: http://www.ciscopress.com/articles/article.asp?p=426638
Q10. Refer to the exhibit.
HostA cannot ping HostB. Assuming routing is properly configured, what is the cause of this problem?
A. HostA is not on the same subnet as its default gateway.
B. The address of SwitchA is a subnet address.
C. The Fa0/0 interface on RouterA is on a subnet that can't be used.
D. The serial interfaces of the routers are not on the same subnet.
E. The Fa0/0 interface on RouterB is using a broadcast address.
Answer: D
Explanation:
Now letu2021s find out the range of the networks on serial link: For the network 192.168.1.62/27:
Increment: 32
Network address: 192.168.1.32
Broadcast address: 192.168.1.63 For the network 192.168.1.65/27: Increment: 32
Network address: 192.168.1.64
Broadcast address: 192.168.1.95
-> These two IP addresses donu2021t belong to the same network and they canu2021t see each other.
Q11. What can be done to secure the virtual terminal interfaces on a router? (Choose two.)
A. Administratively shut down the interface.
B. Physically secure the interface.
C. Create an access list and apply it to the virtual terminal interfaces with the access-group command.
D. Configure a virtual terminal password and login process.
E. Enter an access list and apply it to the virtual terminal interfaces using the access-class
command.
Answer: D,E
Explanation:
It is a waste to administratively shut down the interface. Moreover, someone can still access the virtual terminal interfaces via other interfaces ->
We cannot physically secure a virtual interface because it is u201cvirtualu201d ->.
To apply an access list to a virtual terminal interface we must use the u201caccess-classu201d command. The u201caccess-groupu201d command is only used to apply an access list to a physical interface -> C is not correct.
The most simple way to secure the virtual terminal interface is to configure a username & password to prevent unauthorized login.
Q12. Refer to the exhibit.
What statement is true of the configuration for this network?
A. The configuration that is shown provides inadequate outside address space for translation of the number of inside addresses that are supported.
B. Because of the addressing on interface FastEthernet0/1, the Serial0/0 interface address will not support the NAT configuration as shown.
C. The number 1 referred to in the ip nat inside source command references access-list number 1.
D. ExternalRouter must be configured with static routes to networks 172.16.1.0/24 and 172.16.2.0/24.
Answer: C
Explanation:
The u201clist 1 refers to the access-list number 1.
