E.TK1(config)# router rip TK1(config-router)# network 192.1.1.4 TK1(config-router)# network 192.1.1.128

F.TK1(config)# router rip

TK1(config-router)# version 2

TK1(config-router)# network 192.1.1.0

Answer: A, D, F Explanation:

To establish connectivity on router TK1 the first step is to configure the interfaces with the correct IP address and enable them with the "no shutdown" command as shown in answer choices A and D. The final step is to enable the RIP routing process. Since this network uses VLSM, RIP version 2 will be required to establish connectivity. RIP version 1 is the default RIP version, but it does not support VLSM.

Incorrect Answers:

B:The IP address in use here will conflict with the LAN network configured on TK2.

C:the 192.168.1.4/30 address is a network address, not a host address.

E: In this example we are required to use RIP version 2, not 1. In addition, the IP networks shown are not required. Since RIP assumes classful routing, we only need the single 192.168.1.0 network to be added to the routing process.

QUESTION NO: 4

A network administrator needs to configure a serial link between the main office and a remote location. The router at the remote office is a non-Cisco router. How should the network administrator configure the serial interface of the main office router to make the connection?

A. Main(config)# interface serial 0/0

Main(config-if)# ip address 172.16.1.1 255.255.255.255

Main(config-f)# no shut

B. Main(config)# interface serial 0/0

Main(config-if)# ip address 172.16.1.1 255.255.255.255

Main(config-f)# encapsulation ppp

Main(config-if)# no shut

C. Main(config)# interface serial 0/0

Main(config-if)# ip address 172.16.1.1 255.255.255.255

Main(config-f)# encapsulation frame-relay

Main(config-if)# authentication chap

Main(config-if)# no shut

D. Main(config)# interface serial 0/0

Main(config-if)# ip address 172.16.1.1 255.255.255.255

Main(config-f)# encapsulation ietf

Answer: B Explanation:

The default encapsulation on a serial interface is the Cisco proprietary HDLC. When connecting to routers from another vendor, we will need to use the standards based PPP, which is correctly defined in choice B.

Incorrect Answers:

A: This is not a correct answer because no encapsulation is defined, so the default HDLC will be used, which is a Cisco proprietary protocol.

C:CHAP authentication is only used by PPP, not HDLC.

D:IETF itself is not an encapsulation option on an interface; it is used in frame relay networks, where the encapsulation can be frame relay IETF, but not simply IETF alone.

TestKing2 configuration exhibit:

Two routers named TestKing1 and TestKing2 are connected by their serial interfaces as shown above, but there is no data connectivity between them. The TestKing1 router is known to have a correct configuration. Given the partial configurations shown in the exhibit, what is the problem on the TestKing2 router that is causing the lack of connectivity?

A.The serial line encapsulations are incompatible.

B.The subnet mask is incorrect.

C.The maximum transmission unit (MTU) size is too large.

D.The IP address is incorrect.

E.A loopback is not set.

F.The bandwidth setting is incompatible with the connected interface.

G.None of the above

Answer: D

QUESTION NO: 6

Part of the TestKing network is shown below:

TestKing1 configuration exhibit:

In this TestKing network segment shown above, hosts in network 192.168.2.0 are unable to reach hosts in network 192.168.3.0. Based on the output from Router TestKing1, what are two possible reasons for the failure? (Choose two)

A.The cable that is connected to S0/0 on Router TestKing1 is faulty.

B.The encapsulation that is configured on S0/0 of Router TestKing2 does not match the encapsulation that is configured on S0/0 of Router TestKing1.

C.The IP address that is configured on S0/0 of Router TestKing2 is not in the correct subnet.

D.Interface S0/0 on Router TestKing1 is not receiving a clock signal from the CSU/DSU.

E.Interface S0/0 on Router TestKing2 is administratively down.

F.Interface S0/0 on Router TestKing1 is configured with an incorrect subnet mask.

QUESTION NO: 7

The two TestKing Lab routers shown below are interconnected with back-to-back cables between their serial interfaces. How should the serial interface of the TestKing1 router be configured to establish Layer 3 connectivity between the two routers?

A.TestKing1(config)#interface serial 3 TestKing1(config-if)# clock rate 64000 TestKing1(config-if)# no shutdown

B.TestKing1(config)#interface serial 3

TestKing1(config-if)# ip address 192.168.10.3 255.255.255.0

TestKing1(config-if)# clock rate 64000

C. TestKing1(config)#interface serial 3

TestKing1(config-if)# ip address 192.168.10.3 255.255.255.0

TestKing1(config-if)# clock rate 64000

TestKing1(config-if)# no shutdown

D. TestKing1(config)#interface serial 3

TestKing1(config-if)# ip address 192.168.10.3 255.255.255.0

TestKing1(config-if)# no shutdown

E. None of the above

Answer: D Explanation:

When examining the interface using the show controllers command, the DTE cable is connected so there is no need to specify the clock rate and bandwidth; just specify the IP address and bring up the interface. Only the DCE side of the serial to serial connection is required to specify the clock rate.

QUESTION NO: 8

An administrator cannot connect from TestKing1 to TestKing2. To troubleshoot this problem, the administrator has entered the command shown in the exhibit.

Based on the output shown, what could be the problem?

A.The serial interface has a full buffer.

B.The serial interface is configured for half duplex.

C.The serial interface has the wrong type of cable attached.

D.The serial interface does not have a cable attached.

E.The serial interface is configured for the wrong frame size.

Answer: C Explanation:

According to the figure DTE cable should connect to Testking1 on interface but while examining using show controllers serial 0/0 command it showing that a DCE is connected so the wrong type of cable is being used.

QUESTION NO: 9

While logged into a router you manually shut down the serial 0 interface using the "shutdown" interface configuration command. You then issue the "show interface serial 0" command in exec mode. What could you expect the status of the serial 0 interface to be?

A.Serial 0 is up, line protocol is up

B.Serial 0 is up, line protocol is down

C.Serial 0 is down, line protocol is down

D.Serial 0 is down, line protocol is up

E.Serial 0 is administratively down, line protocol is down

F.Serial 0 is administratively down, line protocol is up

Answer: E Explanation:

To bring down an interface for administrative reasons and, as a side effect, remove the connected router from the routing table, you can use the shutdown interface subcommand. To enable the interface back up, issue the "no shutdown" configuration command.

Incorrect Answers:

A. This is the status of a fully operational interface.

B, C. These are the results of line problems or configuration errors. D, F. These two interface conditions should never be seen.

The network administrator is configuring router TestKing2 to connect to a non-Cisco (Juniper) network. Which two commands would be applied to the S0/0 WAN interface, but not to the Fa0/0 LAN interface? (Choose two.)

A.ip address

B.authentication pap

C.encapsulation ppp

D.speed

E.no shutdown

Answer: B, C

Explanation:

Since we are connecting to a non Cisco device, we must use PPP on the serial interface. PAP authentication is an optional parameter that can also used on this interface. Incorrect Answers:

A, E: Although are indeed configurable on the serial interface, they are also configured on the LAN interface and we are being asked to choose the options that apply to the serial interface only.

D: This is a parameter that can only be set on and Ethernet interface, not on the serial interface.
