A student working in the lab selects a cable that is wired as shown. Which connection types can successfully be made with this cable? (Choose two.)connecting a PC to a routers console port*connecting two routers together via their fast ethernet ports*connecting two switches together at gigabit speedsconnecting a PC to a switch at Gigabit Ethernet speedsconnecting two devices with the same interface type at Fast Ethernet speeds2Which three statements are true about the role of routers in the network? (Choose three.)They propagate broadcasts.They enlarge collision domains.*They segment broadcast domains.They interconnect different network technologies.*Each router interface requires a separate network or subnet.*They maintain a common frame format between LAN and WAN interfaces.3Refer to the exhibit. A network administrator has decided to use packet capture software to uate all traffic from the student subnet on the way to the Internet. To ensure that all packets are captured, what network device should be used to connect the monitoring station to the network between R1 and R2?router*hubswitchwireless access point4A network administrator is required to use media in the network that can run up to 100 meters in cable length without using repeaters. The chosen media must be inexpensive and easily installed. The installation will be in a pre-existing building with limited cabling space. Which type of media would best meet these requirements?*STPUTPcoaxialsingle-mode fibermultimode fiber5Refer to the exhibit. Which three statements are true about the exhibited topology? (Choose three.)Hosts B and C are in the same subnet.*Five broadcast domains are present.*Host B is using a crossover cable to connect to the router.Four broadcast domains are present.*Five networks are shown.Host B is using a rollover cable to connect to the router.6Which three types of connectors are commonly associated with Ciscos V.35 serial cables? (Choose three.)RJ 11*DB 60*Winchester 15 pinDB 9*smart serialRJ 457How many host addresses may be assigned on each subnetwork when using the 130.68.0.0 network address with a subnet mask of 255.255.248.0?30256*20462048409440968Refer to the exhibit. Based on the IP configuration shown, what would be the result of Host A and Host B attempting to communicate outside the network segment?both host A and B would be successful*host A would be successful, host B would failhost B would be successful, host A would failboth Host A and B would fail9Refer to the exhibit. What destination IP address will PC1 place in the header for a packet destined for PC2?192.168.1.1192.168.2.1192.168.2.2192.168.3.1*192.168.3.5410Refer to the exhibit. Which three statements identify the type of cabling that would be used in the segments that are shown? (Choose three.)Segment 1 uses backbone cabling.*Segment 1 uses a patch cable.Segment 3 uses patch cabling.Segment 3 uses vertical cabling.*Segment 3 uses horizontal cabling.*Segment 4 uses vertical cabling.11A company is planning to subnet its network for a maximum of 27 hosts. Which subnet mask would provide the needed hosts and leave the fewest unused addresses in each subnet?255.255.255.0255.255.255.192*255.255.255.224255.255.255.240255.255.255.24812Refer to the exhibit. A student is setting up a home network primarily used for extensive file transfers, streaming video, and gaming. Which network device is best suited to these types of activities in the topology shown?wireless access pointrouterhub*switch13Refer to the exhibit. How many subnets are required to support the network that is shown?2*34514What does the term “attenuation” mean in data communication?*loss of signal strength as distance increasestime for a signal to reach its destinationleakage of signals from one cable pair to anotherstrengthening of a signal by a networking device15To establish a console connection from a computer to a Cisco router, which cable wiring option would be used?*crossover cablestraight through cablerollover cableV.35 cable16What makes fiber preferable to copper cabling for interconnecting buildings? (Choose three.)*greater distances per cable runlower installation cost*limited susceptibility to EMI/RFIdurable connections*greater bandwidth potentialeasily terminated17Refer to the exhibit. A network technician has been allocated the 192.168.1.0/24 private IP address range for use in the network that shown in the exhibit. Which subnet mask would be used to meet the host requirements for segment A of this internetwork?*255.255.255.128255.255.255.192255.255.255.224255.255.255.240255.255.255.24818Which subnet mask would be assigned to the network address of 192.168.32.0 to provide 254 useable host addresses per subnetwork?255.255.0.0*255.255.255.0255.255.254.0255.255.248.019What type of network cable is used between a terminal and a console port?cross-overstraight-through*rolloverpatch cable20Which option identifies the primary interface which would be used for initial configuration of a Cisco router?AUX interfaceEthernet interfaceserial interface*console interface21What are two common methods for setting a UTP Ethernet port to MDI or MDIX operation?
