Q62. - (Topic 4)
Refer to the exhibit.
A company wants to use NAT in the network shown. Which commands will apply the NAT configuration to the proper interfaces? (Choose two.)
A. R1(config)# interface serial0/1 R1(config-if)# ip nat inside
B. R1(config)# interface serial0/1 R1(config-if)# ip nat outside
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 200.2.2.18 255.255.255.252
F. R1(config)# interface fastethernet0/0 R1(config-if)# ip nat inside source 10.10.0.0 255.255.255.0
Answer: B,C
Explanation:
For NAT, you need to define which interfaces are inside and which are outside. The outside interface is the one that connects to the external network, and the one that will be used for translating addresses. The inside interface is for the internal network, and defines the network IP addresses that will get translated to the one specified in the outside network.
Q63. - (Topic 4)
When configuring NAT, the Internet interface is considered to be what?
A. local
B. inside
C. global
D. outside
Answer: D
Explanation:
The first step to deploy NAT is to define NAT inside and outside interfaces. You may find it easiest to define your internal network as inside, and the external network as outside. However, the terms internal and external are subject to arbitration as well. This figure shows an example of this.

Q64. - (Topic 2)
What does a host on an Ethernet network do when it is creating a frame and it does not have the destination address?
A. Drops the frame
B. Sends out a Layer 3 broadcast message
C. Sends a message to the router requesting the address
D. Sends out an ARP request with the destination IP address
Answer: D
Explanation:
In this case, it will send out an ARP request for MAC address of the destination IP (assuming it doesn't already have it in its table) and then address it to the destination's MAC address.
Q65. - (Topic 3)
Which option is a valid IPv6 address?
A. 2001:0000:130F::099a::12a
B. 2002:7654:A1AD:61:81AF:CCC1
C. FEC0:ABCD:WXYZ:0067::2A4
D. 2004:1:25A4:886F::1
Answer: D
Explanation:
IPv6 Address Notation IPv6 addresses are denoted by eight groups of hexadecimal quartets separated by colons in between them. Following is an example of a valid IPv6 address: 2001:cdba:0000:0000:0000:0000:3257:9652 Any four-digit group of zeroes within an IPv6 address may be reduced to a single zero or altogether omitted. Therefore, the following IPv6 addresses are similar and equally valid: 2001:cdba:0000:0000:0000:0000:3257:9652 2001:cdba:0:0:0:0:3257:9652 2001:cdba::3257:9652

To what type of port would a cable with a DB-60 connector attach?
A. Serial port
B. Console port
C. Ethernet port
D. Fibre optic port
Answer: A
Explanation:
Serial Connection
cl_3_dte_male
cl_2_dce
The picture on the left shows a V.35 DTE cable with a male DB60 connector and a male standard 34-pin Winchester-type connector. The right picture shows a V.35 DCE serial cable with a male DB60 connector and a female 34-pin Winchester-type connector. As you probably guessed already, the male connector of the DTE cable is attached to the DCE cable's female connector, this is depicted in the picture below. This is known as a back-to-back connection, and 'simulates' a WAN link. In a real world setup, the DTE cable's male connector typically connects to a port on a CSU/DSU provided by a service provider (i.e. telco), which in turn connects to a CSU/DSU at another location, thru a T1 link for example.
The DB60 connector connects to a Serial interface on a router.

Q68. - (Topic 1)
Which three statements are true about the operation of a full-duplex Ethernet network? (Choose three.)
A. There are no collisions in full-duplex mode.
B. A dedicated switch port is required for each full-duplex node.
C. Ethernet hub ports are preconfigured for full-duplex mode.
D. In a full-duplex environment, the host network card must check for the availability of the network media before transmitting.
E. The host network card and the switch port must be capable of operating in full-duplex mode.
Answer: A,B,E
Explanation:
Half-duplex Ethernet is defined in the original 802.3 Ethernet and Cisco says you only use one wire pair with a digital signal running in both directions on the wire. It also uses the CSMA/CD protocol to help prevent collisions and to permit retransmitting if a collision does occur. If a hub is attached to a switch, it must operate in half-duplex mode because the end stations must be able to detect collisions. Half-duplex Ethernet—typically 10BaseT—is only about 30 to 40 percent efficient as Cisco sees it, because a large 10BaseT network will usually only give you 3- to 4Mbps—at most. Full-duplex Ethernet uses two pairs of wires, instead of one wire pair like half duplex. Also, full duplex uses a point-to-point connection between the transmitter of the transmitting device and the receiver of the receiving device, which means that with full-duplex data transfer, you get a faster data transfer compared to half duplex. And because the transmitted data is sent on a different set of wires than the received data, no collisions occur. The reason you don’t need to worry about collisions is because now Full-duplex Ethernet is like a freeway with multiple lanes instead of the single-lane road provided by half duplex. Full-duplex Ethernet is supposed to offer 100 percent efficiency in both directions; this means you can get 20Mbps with a 10Mbps Ethernet running full duplex, or 200Mbps for FastEthernet.

Which statements accurately describe CDP? (Choose three.)
A. CDP is an IEEE standard protocol.
B. CDP is a Cisco proprietary protocol.
C. CDP is a datalink layer protocol.
D. CDP is a network layer protocol.
E. CDP can discover directly connected neighboring Cisco devices.
F. CDP can discover Cisco devices that are not directly connected.
Answer: B,C,E
Explanation:
CDP (Cisco Discovery Protocol) is a proprietary protocol designed by Cisco to help administrators collect information about both locally attached and remote devices. By using CDP, you can gather hardware and protocol information about neighbor devices containing useful info for troubleshooting and documenting the network.
Q70. - (Topic 5)
Refer to the exhibit.
The network administrator made the entries that are shown and then saved the configuration. From a console connection, what password or password sequence is required for the administrator to access privileged mode on Router1?
A. cisco
B. sanfran
C. sanjose
D. either cisco or sanfran
E. either cisco or sanjose
F. sanjose and sanfran
Answer: B
Explanation:
The enable secret password takes precedence over the enable password, so sanfran will be used.
Q71. - (Topic 5)
Refer to the exhibit.
The two connected ports on the switch are not turning orange or green. What would be the most effective steps to troubleshoot this physical layer problem? (Choose three.)
A. Ensure that the Ethernet encapsulations match on the interconnected router and switch ports.
B. Ensure that cables A and B are straight-through cables.
C. Ensure cable A is plugged into a trunk port.
D. Ensure the switch has power.
E. Reboot all of the devices.
F. Reseat all cables.
Answer: B,D,F
Explanation:
The ports on the switch are not up indicating it is a layer 1 (physical) problem so we should check cable type, power and how they are plugged in.

Q73. - (Topic 3)
Refer to the exhibit.
Which two statements are correct? (Choose two.)
A. This is a default route.
B. Adding the subnet mask is optional for the ip route command.
C. This will allow any host on the 172.16.1.0 network to reach all known destinations beyond RouterA.
D. This command is incorrect, it needs to specify the interface, such as s0/0/0 rather than an IP address.
E. The same command needs to be entered on RouterA so that hosts on the 172.16.1.0 network can reach network 10.0.0.0.
Answer: A,C
Explanation:
This is obviously the default route which is set between the routers and since it is entered in such a manner that it ensures connectivity between the stub network and any host lying beyond RouterA.
Q74. - (Topic 7)
Which device allows users to connect to the network using a single or double radio?
A. access point
B. switch
C. wireless controller
D. firewall
Answer: A
Q75. - (Topic 3)
Which three statements are correct about RIP version 2? (Choose three)
A. It uses broadcast for its routing updates.
B. It supports authentication.
C. It is a classless routing protocol.
D. It has a lower default administrative distance then RIP version 1.
E. It has the same maximum hop count as RIP version 1.
F. It does not send the subnet mask any updates.
Answer: B,C,E
Explanation:
A and E are correct according to the theory of RIP.
RIP version 1 updates are broadcasts, and RIP version 2 updates are multicast to
224.0.0.9 -> B is not correct.
RIP v1 is a classful routing protocol but RIP v2 is a classless routing protocol -> C is
correct.
RIPv1 and RIPv2 have the same default administrative distance of 120 -> D is not correct.
RIPv2 is a classless routing protocol so it does send the subnet mask in updates -> F is not
correct.
