640 - 607 Answer: D Explanation: The shutdown command administratively disables an interface. The result is the interface will be down as will the line protocol. It will end calls in progress. Incorrect Answers: A is incorrect; the statement shows that the interface and the protocols are both up. This would not be the case if the shutdown command were used. B is incorrect; this statement shows that the line is up but the line protocol is down.
640 - 607 Steve McQuerry. Interconnecting Cisco Network Devices. (Cisco Press: 2000) pages 269-273. Q. 62 Which two statements about IP RIP are true? (Choose two.) A. B. C. D. E. F. It limits hop counts to 31. It is a link-state routing protocol. It uses autonomous system numbers. It is capable of load sharing over multiple paths. It uses bandwidth as the metric for path selection.
640 - 607 Explanation: In a switched environment, packets are switched only between ports designated to be within the same “broadcast domain”. VLANs perform network portioning and traffic separation at Layer 2. So, interVLAN communication cannot occur without a Layer 3 device such as a router, because network layer (Layer 3) devices are responsible for communicating between multiple broadcast domains. Note that, at Layer 2, an interface uses ISL to communicate with a switch.
640 - 607 C. D. router(Config)# bandwidth 56000 router(Config-if)# clock rate 56000 Answer: B Explanation: The bandwidth command overrides the default bandwidth. The bandwidth has no effect on the actual speed of the line. Instead, it is used to compute routing metrics ad the load of the link. Bandwidth is expressed in Kilobits. It is specified during interface configuration.

They are allocated for VOL PVOLP. They represent IP classless addresses. They are used by the inter NIC for administration.
640 - 607 Explanation: The network layer defined how to transport traffic between devices that are not locally attached in the same broadcast domain. For the communication the device will require two pieces of information: a logical address associated with the source and destination stations and a path through the network to reach the desired destination. Both of the required information is stored in the devices routing table.
640 - 607 Answer: A, B, E Explanation: A switch has three basic functions, which increase the available bandwidth on a network. These functions are address learning, forward/filter decision, and loop avoidance, Incorrect Answers: C is incorrect; although a switch functions a lot like a multi-port bridge, a switch does not affect – nor is affected by – the hop count. D is incorrect; by their very design Broadcast are meant to be seen by everyone. Steve McQuerry. Interconnecting Cisco Network Devices.
640 - 607 D. One device per segment can currently send frames to the switch. Answer: B Explanation: A switch is usually only handle one media type at a time.

640 - 607 Explanation: Whenever a network is going to be divided by a router a number of factors needs to be considered when selecting a subnet mask. Two factors that need to be considered is the number of networks that you require and the maximum number of host each subnet will require. Incorrect Answers: B is incorrect; DHCP addressing is not relevant in the subnet mask design.
640 - 607 Answer: B Explanation: The show ipx interface command shows the status of the IPS interface and IPS parameters configured on each interface. This includes the IPX address. Incorrect Answers: A is incorrect; there is no such command as show ipx addresses. C is incorrect; the ipx network command is used to enable IPX routing on a particular interface. The parameter is used to identify the network that IPX is enabled on.
640 - 607 Incorrect Answers: B is incorrect; the number 10.2.0.0 is the problem for this option C is incorrect; each network identified must have its own network command. D is incorrect; this is not correct as there is no need to use the subnet mask for the networks. Steve McQuerry. Interconnecting Cisco Network Devices. (Cisco Press: 2000) pages 277, 285-286. Q. 90 Which show command should you use to view Frame Relay local management interface (LMI) traffic statistics? A. B. C. D. E.
640 - 607 Answer: A Explanation: The proper syntax for configuring a second subinterface is interface 0.2 point-to-point. Option A is the closest to this command. The syntax after the command interface is serial interface number (0 in this case).subinterface number (2 in this case) and this followed by the either multipoint or point-to-point. Incorrect Answers: B is incorrect; remember that the syntax is suppose to be number.subinterface number and that there is suppose to be two hyphens in point -to-point.
640 - 607 Q. 93 Which two statements accurately define IP addressing rules? (Choose Two) A. B. C. D.

640 - 607 Explanation: By partitioning the address ranges increases the availability of addresses. Instead of having one size fits all, the address ranges are pooled into different sizes to satisfy different needs, and provides a better distribution of addresses. Incorrect Answers: B is incorrect; hierarchical addressing will not effect the distance between routers. C is incorrect; Hierarchical addressing should DECREASE router memory requirements.
640 - 607 Answer: C Explanation: If no configuration file exists for the router in NVRAM, the operating system executes a question driven initial configuration routine often referred to as the system configuration dialog. This special mode is also known as the setup dialog. Incorrect Answers: A is incorrect; there is no copy mode B is incorrect; you can’t do configurations in user mode. The router only enters this mode when it has already been configured.
640 - 607 C. D. E. A network number and host number. A broadcast number and unicast number. A domain identifier and a device identifier. Answer: C Explanation: The network layer address exists at Layer 3 of the OSI reference model. These address are hierarchical in that they define networks first and then devices or nodes on each of the networks. Incorrect Answers: A is incorrect; a URL is used in the application layer, (HTTP). B is incorrect; this is describing a MAC address which is Layer 2.

640 - 607 Answer: Explanation: The transport layer assembles the packets into data, and prepares the data for the session layer above. The Network layer determines the route of moving data. Remember the Network layer is layer 3, and routers work on layer 3. The network layer includes routing functions, and keep this in mind when the question says determines the best way to move data. On the datalink layer, the actual transmission occurs.
640 - 607 A. B. C. D. Switches create a single collision domain and a single broadcast domain. Routers provide broadcast domains.

B. C. D. E. Recipients acknowledge receipt of data. When buffers are filled to capacity, datagrams are discarded and not re transmitted. Windows are used to control the amount in outstanding acknowledged data segments.
640 - 607 C. D. The data packet is independently routed and the service does not guarantee the packet will be processed in order. A data communication path is established between the requesting entity and the peer device on the remote end system. Answer: A, B, D. Explanation: In order to establish a connection-orientated service, the connection must first be established. An example of this would the TCP/IP suites use of the three-way handshake.
640 - 607 What is an example of a valid MAC address? A. B. C. D. 192.201.63.251 19-22-01-63-25 0000.1234.FEG 00-00-12-34-FE-AA Answer: D. Explanation: MAC address is a uniquely assigned address to each device on the network. The MAC address is 48 bit in length and are expressed as hexadecimal digit. The first 6 digits specify the manufacturer ID and the remaining 6 are unique to host. No two MAC addresses can be same.
640 - 607 Incorrect Answers: A is incorrect; is this series of commands the network 10.1.0.1 is not a valid command. C is incorrect; if 4 networks are directly connected they must have their own network command. D is incorrect; there is no need to include a subnet mask with a network command. Steve McQuerry. Interconnecting Cisco Network Devices. (Cisco Press: 2000) pages 278-9. Q.
640 - 607 A. B. C. D. A Filtering table is developed for each switch. Frame Tagging defines a unique user defined ID to each frame. A unique identifier is placed in the header of each frame as it is forwarding between switches. Frame Tagging is technique that examines particular information about each frame based on userdefined offsets. Answer: B, C. Explanation: Frame tagging or frame identification uniquely assigns a user-defined Id to each frame. This is sometimes referred to as VLAN ID.
640 - 607 D. The application layer must assume responsibility for correct sequencing of the data packets. Answer: A. Explanation: One of the benefits of a connection-orientated protocol is that there is a guarantee of delivery of data. This guarantee is provided as the two communicating exchange PDUs during transmission and if an acknowledgement is not received then the data is retransmitted. As can be imagined this exchange of PDUs can cause an increase in overhead.
640 - 607 In store and forward mode, the switch must receive the complete frame before forwarding takes place. The destination and source addresses are read, the cyclic redundancy check (CRC) is performed, relevant filters are applied, and the frame is forwarded. If the CRC is bad, the frame is discarded. The latency (or delay) through the switch varies with frame length. Incorrect Answers: A: Is wrong because the latency changes with the frame size.
