2.TFTP server

3.ROM (not full Cisco IOS)

QUESTION NO: 21

What will a new TestKing router do during startup if a configuration file is not located in NVRAM?

A.It will search for the configuration file in the locations specified by boot system commands.

B.It will search for the configuration file in flash and if no configuration file is found there, it will enter the setup dialog.

C.It will search for the configuration file on a TFTP server and if no configuration file is found there, it will enter the setup dialog.

D.It will search for the configuration file in flash and if no configuration file is found there, it will load a limited configuration file from ROM.

E.It will search for the configuration file on a TFTP server and if no configuration file is found there, it will load a limited configuration file from ROM.

Answer: C Explanation:

When a router boots and is able to locate the IOS it begins to load the configuration file. The configuration file, saved in NVRAM, is loaded into main memory and executed one line at a time. These configuration commands start routing processes, supply addresses for interfaces, and set media characteristics.

If no configuration file exists in NVRAM, the router attempts a network boot and sends a broadcast request for the file on a TFTP server. If this is also not found, the operating system executes a question-driven initial configuration routine called the system configuration dialog.

QUESTION NO: 22

A TestKing router boots to the prompt shown in the exhibit below. What does this signify, and how should the network administrator respond?

Exhibit:

A.This prompt signifies that the configuration file was not found in flash memory. The network administrator should use TFTP to transfer a configuration file to the router.

B.This prompt signifies that the IOS image in flash memory is invalid or corrupt. The network administrator should use TFTP to transfer an IOS image to the router.

C.This prompt signifies that the configuration file was not found in NVRAM. The network administrator should follow the prompts to enter a basic configuration.

D.This prompt signifies that the router could not authenticate the user. The network administrator should modify the IOS image and reboot the router.

Answer: B

Explanation:

The default boot sequence for Cisco IOS software:

1.NVRAM

2.Flash (sequential)

3.TFTP server (network boot)

4.ROM (partial IOS)

If a router boots up in ROM mode as shown in this example, it means that the router was unsuccessfully able to find a valid IOS to boot from, and a valid IOS image will need to be loaded onto it.

QUESTION NO: 23

A TestKing router boots up in ROMMON mode. What is ROM Monitor (ROMMON)?

A.A memory component for storing the saved configuration file

B.A memory management tool

C.An operating system used for hardware troubleshooting and for password recovery

Leading the way in IT testing and certification tools, www.testking.com

- 362 -

D.Temporary storage space for the router operating files

E.The source of the primary Cisco IOS software image

F.None of the above

Answer: C Explanation:

The ROM Monitor is a very limited code set that enables you to perform elementary functions to manually get the router or switch back to a functioning state. You can perform low-level diagnostics and even copy a new IOS file to the Cisco device over the console port. It is also used after the break sequence is issued during bootup for password recovery use.

A.Rollover cable

B.Console cable

C.Crossover cable

D.Straight-through cable

E.Serial cable

Answer: D Explanation:

QUESTION NO: 2

You are trying to connect directly into the LAN prot of a TestKing router. You want to telnet to the local Cisco router using TCP/IP but cannot create a session.

What should you do to resolve the problem?

A.Use a straight-through cable to connect your computer's COM port to the router's console port.

B.Use a crossover cable to connect your computer's COM port to the router's console port.

C.Use a straight-through cable to connect your computer's COM port to the router's Ethernet port.

D.Use a crossover cable to connect your computer's Ethernet port to the router's Ethernet port.

E.Use a rollover cable to connect your computer's Ethernet port to the router's Ethernet port.

F.Use a straight-through cable to connect your computer's Ethernet port to the router's Ethernet port.

G.None of the above

Answer: D Explanation:

In order to connect directly to a router via telnet, you must connect to the router via one of the LAN ports. When connecting directly to the Ethernet port with a PC without the use of a switch or hub, a crossover cable must be used.

Incorrect Answers:

- 364 -

A, B, C. In order to telnet directly into the router via a TCP/IP connection, the COM port of the PC can not be used. The COM port is used for direct terminal emulation programs such as HyperTerminal.

E.Rollover cables are used for console connections into the router, not for TCP/IP connections.

F.Straight through cables are used for connections into a switch or hub from the PC. It will not work for direct Ethernet connections into the router.

QUESTION NO: 4

Refer to the exhibit shown below.

A.The bandwidth is set too low.

B.A protocol mismatch exists.

QUESTION NO: 5

The following port types are installed on a TestKing device:

From the choices shown above, which port can be used for a WAN T1 connection?

A.Console

B.Serial 0

C.AUI

D.BRI

E.None of the above

Answer: B Explanation:

From the choices above, only the serial connection can be used for a data T1. In this case, the serial interface would connect to an external CSU/DSU.

Incorrect Answers:

A: The router includes an asynchronous serial console port and an auxiliary port. The console and auxiliary ports provide access to the router either locally using a console terminal connected to the console port, or remotely using a modem connected to the auxiliary port.

C:For flexibility, some Cisco routers provide a generic AUI connector for Ethernet ports. These AUI ports are designed to connect to an external transceiver for conversion to a specific media type (such as twisted pair, coax, or fiber).

D:BRI ports are used to connect to ISDN links, not T1.

Section 4: Configure, verify, and troubleshoot RIPv2 (5 questions)

QUESTION NO: 1

Part of the TestKing WAN is shown below:

The TestKing network shown in the exhibit above is running the RIP version 2. This network has converged, and the routers in this network are functioning properly. Then, the FastEthernet0/0 interface on router TestKing1 goes down. In which two ways will the routers in this network respond to this change? (Choose two)

A.All routers will reference their topology database to determine if any backup routes to the 192.168.1.0 network are known.

B.Routers router TestKing2 and router TestKing3 mark the route as inaccessible and will not accept any further routing updates from router TestKing1 until their hold-down timers expire.

C.When router router TestKing2 learns from router TestKing1 that the link to the 192.168.1.0 network has been lost, router TestKing2 will respond by sending a route back to router TestKing1 with an infinite metric to the 192.168.1.0 network.

D.Because of the split-horizon rule, router router TestKing2 will be prevented from sending erroneous information to router TestKing1 about connectivity to the 192.168.1.0 network.

E.router TestKing1 will send LSAs to router TestKing2 and router TestKing3 informing them of this change, and then all routers will send periodic updates at an increased rate until the network again converges.

Answer: C, D

Explanation:

RIP version 2 will send triggered updates when the topology changes like when a link goes down.

The following are the key characteristics of RIPv2 pertaining to this question: 1.

Leading the way in IT testing and certification tools, www.testking.com

- 369 -

Split horizon - RIP doesn't advertise routes back out the interface in which they came. Or put another way, a router won't tell a neighbor about routes that the neighbor presumably already knows about. That would be silly, and could cause a loop in certain circumstances.

2.Triggered update - RIP will send an update out just a soon as the routing table changes. He won't wait for the Update timer to expire.

3.Route poisoningRIP will tell other routers that a failed route is junk by advertising it with an infinite metric (which is 16 for RIP), effectively poisoning it.
