It is also known as a patch cable. You can connect a switch to a router using a straight-through cable.
Which statement is TRUE of the CSMA/CD Ethernet media access method? Each station is allotted a time slot in which they can transmit data. It requires centralized monitoring and control. It is ideal for a switched network environment. It uses a back-off algorithm to calculate a random time value.
It uses a back-off algorithm to calculate a random time value. The Carrier Sense Multiple Access - Collision Detection (CSMA/CD) Ethernet media access control (MAC) method uses a back-off algorithm to calculate random times to transmit packets across a channel. When two stations start transmitting at same time, their signals will collide. The CSMA/CD method detects the collision and causes both stations to hold the retransmission for an amount of time determined by the back-off algorithm. This is done in an effort to ensure that the retransmitted frames do not collide.
Are APICs (Application Policy Infrastructure Controller) directly involved in forwarding traffic?

You use a computer named Wkst1 on a TCP/IP network, which is installed with an application that uses UDP to send a file from your computer to a computer named Wkst2. Data collisions occur, and several data packets are lost during transmission. What will most likely occur as a result of losing the packets during transmission? (Choose two.) The application will automatically retransmit the packets. The application will drop the packets. The protocol will drop the packets. The protocol will automatically retransmit the packets.
The application will automatically retransmit the packets. The protocol will drop the packets. User Datagram Protocol (UDP) is a connectionless protocol; thus, it will drop the packets and it will not automatically retransmit them. Because an application is not typically responsible for transmitting data packets across a network, the application in this scenario cannot drop the packets. Instead, an application that uses UDP will usually detect that UDP has dropped packets, and the application will retransmit any dropped packets.

You install a second NIC in your Linux computer. Then you log on to the computer as root. You want to configure the new NIC with the IP address 192.168.0.1 and the subnet mask 255.255.255.0. Which command should you issue at a command prompt to configure the NIC? ifconfig eth1 192.168.0.1 netmask 255.255.255.0 up ifconfig eth0 192.168.0.1 subnet 255.255.255.0 up ipconfig eth1 192.168.0.1 netmask 255.255.255.0 up ipconfig eth0 192.168.0.1 subnet 255.255.255.0 up
ifconfig eth1 192.168.0.1 netmask 255.255.255.0 up On a Linux computer, you would use the ifconfig command to configure a network interface card (NIC). The first NIC in a Linux computer is typically named eth0, and the second NIC is named eth1. Therefore, you should log on to the Linux computer as root, which is also known as the superuser, and issue the command ifconfig eth1 192.168.0.1 netmask 255.255.255.0 up to configure the second NIC. The 192.168.0.1 portion of the command configures the IP address for the NIC, the netmask 255.255.255.0 portion of the command configures the subnet mask for the NIC, and the up portion of the command activates the NIC. A similar procedure would be used on a UNIX computer.
You receive the following error message after addressing and enabling an interface: %192.168.16.0 overlaps with FastEthernet0/0 Which of the following are NOT the causes of the error message? (Choose two.) incorrect subnet mask in the new interface incorrect encapsulation configured incorrect IP address on the new interface failure to issue the no shutdown command
incorrect encapsulation configured failure to issue the no shutdown command The error message %192.168.16.0 overlaps with FastEthernet0/0 indicates that the newly configured interface is in the same subnet as an existing interface. This can occur if there is an incorrect subnet mask or an address that inadvertently places the new interface in that subnet. Each router interface must be in a different subnet to function. For example, when the series of commands below is executed on a router, it will elicit the error message because the two IP addresses used are in the same subnet given the subnet mask in use.
Which type of switching process requires a switch to wait for the entire frame to be received before forwarding it to a destination port? frame-forward fragment-free store and forward cut-through
store and forward The store and forward switching process requires a switch to wait until the entire frame is received before forwarding it to a destination port. The store and forward method increases latency as it buffers the entire frame and runs a frame check sequence (FCS) before forwarding it to the destination port. However, it ensures error-free frame forwarding because its filters all frame errors.

RouterA and RouterB, which connect two locations, are unable to communicate. You run the show running-configuration command on both router interfaces, RouterA and RouterB. The following is a partial output: routerA#show running-config interface Serial0 description Router_A ip address 192.10.191.2 255.255.255.0 encapsulation ppp no ip mroute-cache clockrate 64000 routerB#show running-config interface Serial1 description Router_B ip address 192.10.192.1 255.255.255.0 encapsulation ppp no ip mroute-cache clockrate 64000 Based on the information given in the output, what are the likely causes of the problem? (Choose two.) The Layer 2 framing is misconfigured. The IP address defined is incorrect. Both routers cannot have a clock rate defined. Both routers cannot have an identical clock rate. At least one of the routers must have the ip mroute-cache command enabled.
The IP address defined is incorrect. Both routers cannot have a clock rate defined. Two possible causes of the problem are that the IP addresses are incorrect as defined, or that both routers have a defined clock rate. The IP addresses on the routers are in different subnets. The IP addresses need to be changed to fall in the same subnet.
You are considering a candidate for a job as a Cisco network technician. As part of the assessment process, you ask the candidate to write down the commands required to configure a serial interface, in the proper order with the correct command prompts. The candidate submits the set of commands shown below (line numbers are for reference only): 1 Router# configure terminal 2 Router(config)# interface S0 3 Router(config)# ip address 192.168.5.5 4 Router(config-if)# enable interface 5 Router(config-if)# description T1 to Raleigh Which part(s) of this submission are incorrect? (Choose all that apply.) The prompt is incorrect on line 4 The command on line 4 is incorrect The IP address on line 3 is missing a subnet mask The prompt is incorrect on line 1 The prompt is incorrect on line 3 The prompt is incorrect on line 5 The description command must be executed before the interface is enabled
The IP address on line 3 is missing a subnet mask The command on line 4 is incorrect The prompt is incorrect on line 3 The IP address is missing a subnet mask, the prompt is incorrect on line 3, and the command enabling the interface (line 4) is incorrect. The correct prompts and commands are as follows: Router# configure terminal Router(config)# interface S0 Router(config-if)# ip address 192.168.5.5 255.255.255.0 Router(config-if)# no shutdown Router(config-if)# description T1 to Raleigh The prompt for line 3 would be Router(config-if)# because the interface S0 command was issued immediately prior to the ip address 192.168.5.5 command. The prompt will remain Router(config-if)# for lines 3, 4, and 5 as each command that applies to the S0 interface is executed, including the description command. The command to enable the interface is no shutdown, not enable interface. Therefore, the command executed on line 4 was incorrect.

Which statement best describes a converged network? a network with a mix of voice, video, and data traffic a network with mix of data and video traffic a network with a mix of voice and video traffic a network with real-time applications
a network with a mix of voice, video, and data traffic A converged network is a combination of voice, video, and data traffic. Network convergence is a migration from maintaining multiple service-specific networks, namely data, voice, and video, to a single IP-based network. All services are delivered on the same network, reducing infrastructure costs. Despite the benefits that network convergence provides, it is highly susceptible to network delays, especially for real-time traffic.

You are purchasing a device to upgrade your network. You need to determine the type of device required as well as the number and type of required interfaces. The device will host three LAN subnets and a T1 Internet connection. Which of the following devices and interface combinations will support this requirement without providing any unnecessary interfaces or using subinterfaces? a switch with one modem and three serial interfaces a router with one serial interface and one Ethernet interface a router with one serial interface and three Ethernet interfaces a switch with one Ethernet interface and three serial interfaces
router with one serial interface and three Ethernet interfaces This deployment will require a router with one serial interface and three Ethernet interfaces. When LAN subnets and the Internet must be connected, you must deploy a device that can make decisions based on IP addresses. This is the function of a router. Each LAN subnet will require a separate Ethernet interface, and the T1 connection requires a serial interface, so the router must have one serial interface and three Ethernet interfaces.
Which of the following commands would allow you to determine the bandwidth of an interface? show interfaces show cdp show interfaces accounting show cdp neighbors
show interfaces
Which Cisco IOS command would you use to troubleshoot IP addressing problems? show config-file show config show running-config ipconfig /all

Which of the following addresses will a switch use to populate the CAM table? *source IP addresses *destination IP addresses *source MAC addresses *destination MAC addresses
source MAC addresses A switch will use source MAC addresses to populate the Content Addressable Memory (CAM) table. The CAM table, which is also called the switching table, is used by a switch to discover the relationship between the OSI layer 2 address of the device and the physical port used to reach the device
You are the network administrator for your company. The network at the company's office is due to be upgraded, and you have been assigned the responsibility of identifying the requirements for designing the network. You need to provide network connectivity to 200 client computers that will reside in the same sub network, and each client computer must be allocated dedicated bandwidth. Which device should you use to accomplish the task? router hub firewall switch
switch You should use a switch to accomplish the task in this scenario. A switch is used to provide dedicated bandwidth to each node by eliminating the possibility of collisions on the switch port where the node resides. Switches work at Layer 2 in the Open System Interconnection (OSI) model and perform the function of separating collision domains. When a node resides in its own collision domain, the possibility of collisions (which slow throughput due to the subsequent but necessary retransmission) is eliminated. The advantage of using a switch instead of a hub is that a switch provides dedicated bandwidth to each client, while all connected clients share the bandwidth on a hub.
Which of the following tables is used by a switch to discover the relationship between the layer 2 address of a device and the physical port used to reach the device *the FIB table *the ARP table *the CAM table *the adjacency table *the VLAN table
the CAM table The CAM table is used by a switch to discover the relationship between the OSI Layer 2 address and the physical port used to reach the device
