QUESTION 107 To upgrade a network, emphasis must be placed on efficiency and error-free transport rather than fast transport. For this purpose, new switches had been purchased. Which switching mode should be configured on these new switches to have the desired effect?

A. 802.1q forwarding

B. VTP transparent mode

C. cut-through

D. store-and-forward

E. fragment-free

F. frame-filtering Answer: D Explanation: The Switch receives and stores all bits in the frame before forwarding the frame. This allows switch to check the FCS before forwarding the frame. FCS is Ethernet Trailer. Incorrect answers:

E. The Switch performs the address table lookup as soon as the destination address field in the header is received. The first bits in the frame can be sent out to out port before the final bits in the incoming frame are received. This does not allow the switch to discard frames that fail the FCS check. This is also same as C. But Switch waits 64 bytes to be received before forwarding the first bytes of the outgoing frame. Collisions may occur during first 64 bytes of the frame. Frames in error due to collision will not be forwarded. The FCS still cannot be checked. B, D, F: They are not related to Switch mode transport.

QUESTION 117 You are a network technician at Cisco Highway, Inc. You are installing a new workstation to the Cisco Highway network. The relevant network segment is shown in the following exhibit:

What should be the IP address of the host?

A. 192.168.5.55

B. 192.168.5.47

C. 192.168.5.40

D. 192.168.5.32

E. 192.168.5.14 Answer: C Explanation The network uses a 28bit subnet (255.255.255.240). This means that 4 bits are used for the networks and 4 bits for the hosts. This allows for 14 networks and 14 hosts (2n-2). The last bit used to make 240 is the 4th bit (16) therefore the first network will be 192.168.5.16. The network will have 16 addresses (but remember that the first address is the network address and the last address is the broadcast address). In other words, the networks will be in increments of 16 beginning at 192.168.5.16/28. The router interface E0 has the IP address 192.168.5.33. Therefore it is on the 2nd network (192.169.5.32/28). The host must also be on this network. Valid IP addresses for hosts on this network are: 192.168.5.33-192.168.5.46. Incorrect Answers:

A: 192.168.5.55 is on network 192.168.5.48. It is not on the same network as the router interface.

B: This is a broadcast address.

D: This is a network address.

E: This is not a valid address for a 28 bit subnet mask. The first network address should be 192.168.5.16.

QUESTION 118 Which protocol allows the configuring of a new VLAN to be distributed to all the switches in a domain in a switch network?

A. STP

B. VTP

C. EGRP

D. SNMP

E. DHCP Answer: B Explanation: Sybex CCNA Study Guide 4th Edition (Page 359) " The basic goals of VLAN Trunking Protocol (VTP) are to manage all configured VLANs across a switched internetworking and to maintain consistency throughout that network. VTP allows an administrator to add, delete, and rename VLANs-information that is then propagated to all other switches in the VTP domain."

QUESTION 119 You are a network technician at Cisco Highway, Inc. A newly pointed trainee wants to know which of the following are types of crosstalk. What would your response be? (Choose all that apply.)

A. near-end crosstalk(NEXT)

B. middle open-end crosstalk(MOEXT)

C. power sum near-end crosstalk(PSNEXT)

D. jitterry crosstalk(JEXT)

E. far end crosstalk(FEXT) Answer: A, C, E Explanation: Near End Crosstalk (NEXT) is crosstalk measured at the transmitting end of the cable. Far End Crosstalk (FEXT) is measured at the far end from where the signal was injected into the cable. Power Sum NEXT (PSNEXT) is basically a mathematical calculation that simulates all four pairs being energized at the same time. PSNEXT calculations are used to ensure that a cable will not exceed crosstalk noise performance requirements when all pairs are operating simultaneously. PSNEXT is typically used in Gigabit Ethernet, rather than 10BaseT or 100BaseT. Reference: Sybex CCNA 4.0 - P. 30

A. Layer 2

B. Layer 3

C. Layer 4

D. Layer 5

E. Layer 6

F. Layer 7 Answer: C Explanation The Transport layer (Layer 4) defines several functions, including the choice of protocols. The most important Layer 4 functions are error recovery and flow control. The transport layer may provide for retransmission, i.e., error recovery, and may use flow control to prevent unnecessary congestion by attempting to send data at a rate that the network can accommodate, or it might not, depending on the choice of protocols. Multiplexing of incoming data for different flows to applications on the same host is also performed. Reordering of the incoming data stream when packets arrive out of order is included. Examples include: TCP, UDP, and SPX.

QUESTION 138 One of your trainees wants to know which of the following is types of flow control one can expect while working in a Cisco network environment. What can you tell him? (Select three options.)

A. Congestion Avoidance.

B. Learning.

C. Buffering.

D. Windowing.

E. Cut-Throat. Answer: A, C, D Explanation: There are three commonly used methods for handling network congestion: Source Quench Messages Source quench messages are used by receiving devices to help prevent their buffers from overflowing. The receiving device sends a source quench message to request that the source reduce its current rate of data transmission. Buffering Buffering is used by network devices to temporarily store bursts of excess data in memory until they can be processed. Occasional data bursts are easily handled by buffering. However, buffers can overflow if data continues at high speeds Windowing Windowing is a flow-control method in which the source device requires an acknowledgement from the destination after a certain number of packets have been transmitted.

1. The source device sends a few packets to the destination device.
2. After receiving the packets, the destination device sends an acknowledgment to the source.
3. The source receives the acknowledgment and sends the same amount of packets.
4. If the destination does not receive one or more of the packets for some reason (such as overflowing buffers),

it does not send an acknowledgment. The source will then retransmits the packets at a reduced transmission rate.

QUESTION 139 Consider the address 192.168.15.19/28, which of the following addresses are valid host addresses on this subnet? (Select two options.)

A. 192.168.15.17

B. 192.168.15.0

C. 192.168.15.29

D. 192.168.15.16

E. 192.168.15.31 Answer: A, C Explanation The network uses a 28bit subnet (255.255.255.240). This means that 4 bits are used for the networks and 4 bits for the hosts. This allows for 14 networks and 14 hosts (2n-2). The last bit used to make 240 is the 4th bit (16) therefore the first network will be 192.168.15.16. The network will have 16 addresses (but remember that the first address is the network address and the last address is the broadcast address). In other words, the networks will be in increments of 16 beginning at 192.168.15.16/28. The IP address we are given is 192.168.15.19. Therefore the other host addresses must also be on this network. Valid IP addresses for hosts on this network are: 192.168.15.17-192.168.15.30. Incorrect Answers:

A. near-end crosstalk(NEXT)

B: This is not a valid address for a 28 bit subnet mask. The first network address should be 192.168.15.16.

D: This is a network address.

E: This is a broadcast address.

QUESTION 146 In which VTP mode should a catalyst switch be to be able to delete and add VLANs to a management domain?

A. Transparent

B. Server

C. Domains

D. Client

E. Users. Answer: B Explanation: VTP Modes If you intend to make a switch part of a VTP management domain, each switch must be configured in one of three possible VTP modes. The VTP mode assigned to a switch will determine how the switch interacts with other VTP switches in the management domain. The three VTP modes that can be assigned to a Cisco switch include server mode, client mode, and transparent mode. Each of these roles is outlined below: Server Mode Once VTP is configured on a Cisco switch, the default mode used is Server Mode. In any given VTP management domain, at least one switch must be in Server Mode. When in Server Mode, a switch can be used to add, delete, and modify VLANs, and this information will be passed to all other switches in the VTP management domain. Client Mode When a switch is configured to use VTP Client Mode, it is simply the recipient of any VLANs added, deleted, or modified by a switch in Server Mode within the same management domain. A switch in VTP client mode cannot make any changes to VLAN information. Transparent Mode A switch in VTP Transparent Mode will pass VTP updates received by switches in Server Mode to other switches in the VTP management domain, but will not actually process the contents of these messages. When individual VLANs are added, deleted, or modified on a switch running in transparent mode, the changes are local to that particular switch only, and are not passed to other switches in the VTP management domain. Based on the roles of each VTP mode, the use of each should be more or less obvious. For example, if you had 15 Cisco switches on your network, you could configure each of them to be in the same VTP management domain. Although each could theoretically be left in the default Server Mode, it would probably be easier to leave only one switch in this configuration, and then configure all remaining switches for VTP Client Mode. Then, when you need to add, delete, or modify a VLAN, that change can be carried out on the VTP Server Mode switch and passed to all Client Mode switches automatically. In cases where you need a switch to act in a relatively standalone manner, or do not want it to propagate information about its configured VLANs, use Transparent Mode. Incorrect Answers:

D: CLIENT mode merely accepts changes made by the switch that is connected and in SERVER mode.

QUESTION 152 One of your trainees asked you which parameter must be supplied when initializing the IGRP routing process. What is your response?

A. Connected subnet numbers

B. Register administrative subnet masks

C. IP address mask

D. Autonomous system number

E. Metric weights Answer: D Explanation: You configure IGRP just like RIP, except that the router igrp command has an additional parameter - the autonomous system (AS) number. The term autonomous system refers to a network that is within the control of a single company or organization. The term AS number refers to a number assigned to a single company or organization when it registers its connection to the Internet. However, for IGRP, you do not need a registered AS number. All that is needed for IGRP to work is for all the routers to use the same AS number. Reference: CCNA Self-Study CCNA ICND exam certification Guide (Cisco press, ISBN 1-58720-083-X) Page 165

QUESTION 160 Study the Exhibit below carefully:

In the illustration, Host Cisco Highway1 is trying to communicate with Host Cisco Highway2. The e0 interface on Cisco HighwayC is down. Which of the following are true? (Select two options.)

A. Cisco HighwayC will make use of ICMP to inform Cisco Highway 1, Cisco HighwayA, and Cisco HighwayB that Host 2 is unreachable.

B. Cisco HighwayC will send a Destination Unreachable message type.

C. Cisco HighwayC will make use of ICMP to inform Cisco Highway 1 that Cisco Highway 2 is unreachable.

D. Cisco HighwayC will use ICMP to inform Cisco HighwayB that Cisco Highway2 is unreachable.

E. Cisco HighwayC will issue a Router Selection message type.

F. Cisco HighwayC will issue a Source Quench message type. Answer: B, C Explanation ICMP is an error-reporting protocol for IP. When datagram delivery error occur, ICMP reports these errors to the sender of the datagram. When the e0 interface on Cisco Highway C goes down, Cisco Highway C uses ICMP to send a message back to Cisco Highway 1 indicating that the datagram could not be delivered. ICMP does not correct the encountered network problem.

Cisco Highway C will not notify the intermediary devices of the delivery failure. Therefore, Cisco Highway C will not send ICMP messages to Cisco Highway B. Datagrams contain only source and destination IP addresses, they do not contain information about all the intermdiary devices. The reporting device ( Cisco Highway C) has only the sender's IP address with which to communicate. Although Cisco Highway A and B are not notified directly, they might become aware of the down interface on Cisco Highway C. However, disseminating this information to neighbor routers is not the function of ICMP. ICMP reports on the status of the delivered packet to the sender, its function is not to propagate information about network changes.
