Refer to the exhibit. Each media link is labeled. What type of cable should be used to connect the different devices? Connection 1 - rollover cable Connection 2 - straight-through cable Connection 3 - crossover cable Connection 1 - crossover cable Connection 2 - rollover cable Connection 3 - crossover cable Connection 1 - straight-through cable Connection 2 - crossover cable Connection 3 - crossover cable Connection 1 - straight-through cable Connection 2 - crossover cable Connection 3 - straight-through cable Connection 1 - crossover cable Connection 2 - straight-through cable Connection 3 - crossover cable

11	Refer to the exhibit. What type of cable connection is displayed? straight-through patch cable rollover cable crossover cable console cable

12	How many bits have been borrowed to subnet the address 189.13.64.45 255.255.255.248? 4 5 12 13 20 21

13

A network administrator must explain to a department manager the difference between how Layer 2 and Layer 3 devices handle data. What should the administrator tell the department manager? (Choose two.) A Layer 2 device will decide where to send data based solely on the source MAC address. A Layer 2 device will decide where to send data based solely on the destination MAC address. A Layer 2 device will decide where to send data based solely on the destination IP address. A Layer 3 device will decide where to send data based solely on the source IP address. A Layer 3 device will decide where to send data based solely on the destination IP address. A Layer 3 device will decide where to send data based solely on the destination MAC address.

14	Which address represents the dotted decimal equivalent of the binary address 10101101.00101011.11001001.00000011? 169.35.200.2 169.43.201.3 173.35.201.2 173.43.201.3 175.13.193.2 175.43.193.3

15

Refer to the exhibit. What would be the effects of replacing the hub with a switch? (Choose two.) Each host will change from shared bandwidth to dedicated bandwidth. Each host will change from dedicated bandwidth to shared bandwidth. The number of collision domains will increase. The number of collision domains will decrease. The number of networks will increase. The number of networks will decrease.

16	What are some of the characteristics of CAT 5 UTP cable? (Choose two.) It is difficult to terminate the cable. It is more expensive than any other type of LAN cabling. It is a four-pair wire medium. It is not affected by EMI or RFI. The twisted wire pairs cause a cancellation effect.

17	Which device creates both collision and broadcast domains? switch hub bridge router repeater

18	How does a device on a LAN detect an error in a frame? It sends a copy of the frame back to the sender for verification. It compares the FCS in the frame to the one that the computer calculates from the contents of the frame. It checks the destination address to verify that the frame was really intended for it. It sends out a jam signal to all nodes on the network.

19	Refer to the exhibit. A network administrator is given a single network address of 192.168.16.0 and must configure the networks in the exhibit. The routing protocol being used is RIP version 1. Which subnet mask should be used? 255.255.255.192 255.255.255.224 255.255.255.240 255.255.255.248

20	What can be learned if a ping to address 127.0.0.1 fails? The remote host located at 127.0.0.1 is not reachable. The ability to ping has been disabled on the computer. The TCP/IP protocols are not loaded. The default gateway is not responding.

21

A network administrator has just connected a new switch to a router with a crossover cable. The Fast Ethernet interface on the router has already been configured but there are no link lights on the router or the switch. What could the problem be? The crossover cable is faulty and needs to be replaced with a new crossover cable. The wrong cable was used and needs to be replaced with a straight-through Ethernet cable. The switch has not been configured yet and the Ethernet port is down. The router was configured with an incorrect IP address on the Ethernet interface.

22

Host A attempts to send data to another host with a known IP address. When Host A sends an ARP request to find the MAC address of the desired host, Host A receives in reply the MAC address of the local router interface. What can be concluded from this response? Host A does not have the correct address for the desired host. The desired host is located on another segment from Host A. The local router is not functioning properly. The desired host and the local router have the same IP address.

23

Host A sends data to Host B, which is located on the same network segment. What action is taken by all hosts on that segment? The NIC in each device checks to see if its MAC address matches the destination MAC address carried by the data frame. The NIC in each device checks to see if its MAC address matches the source MAC address carried by the data frame. Because their MAC addresses are different, the NIC in each device checks the IP address for matches. The NIC in each device checks to see if its IP address matches the source IP address carried by the data frame.

24	When a switch is powered on, it must begin to populate its bridging table. What information is added to the bridging table from incoming packets? source MAC address and incoming port number destination MAC address and incoming port number source IP address and incoming port number destination IP address and incoming port number

25	HostA and HostB lack connectivity. Which option is a Layer 3 issue that could be causing the problem? encapsulation mismatch IP addressing and routing framing errors bit synchronization problems

26	A network administrator has noticed an excessive number of collisions on one subnetwork of the LAN. Which device could be added that would create a solution to the problem? hub router switch transceiver

27	What are two characteristics of link-state protocols? (Choose two.) use more bandwidth for overhead when converging work well for stub networks more router memory required for tables split-horizon strictly followed slow to converge impossible to configure statically

28	Which task does a CSU/DSU perform? packet routing security filtering connects router serial interface to telco dials the backup WAN connection
