4.4.10 Practice Questions

You have a network connected using a physical star topology. One of the drop cables connecting a workstation has been removed. Which of the following best describes what affect this will have on network communications? Devices on one side of the missing cable will be able to communicate with each other; devices on the other side of the missing cable will not be able to communicate. All devices except the device connected with the drop cable will be able to communicate. No devices will be able to communicate. Devices on one side of the missing cable will be able to communicate with each other; devices on the other side of the missing cable will be able to communicate with each other. All devices will be able to communicate.

All devices except the device connected with the drop cable will be able to communicate.

During a network infrastructure upgrade, you have replaced two 10 Mbps hubs with switches and upgraded from Category 3 UTP cable to Category 5e. During the process, you accidentally cut the upgraded from Category 3 UTP cable to Category 5e. During the process, you accidentally cut the Cat 5e patch cable that stretches from the network printer to the upgraded switch. What is the impact on the network? All network nodes authenticated by the same server as the printer will be unavailable. All network nodes on the same subnet as the printer will be unavailable. All network nodes connected to the switch will be unavailable. All network nodes, including the printer, will be available. All network nodes except the printer will be available.

All network nodes except the printer will be available.

You are moving a client to a new location within an Ethernet network. Previous to the move, the client system did not have difficulty accessing the network. During the relocation, you attach cables from the client system to the wall jack and from the patch panel to the switch. Once connected, you do not get a link light on the network card or the switch. You swap out the cable running between the patch panel and the switch with a known working one, but you still cannot connect. Which of the following might you suspect is the problem? Faulty termination Failed patch cable between the client system and the wall jack. Incorrect duplex settings Server software configuration error. Failed network card. Failed switch.

Failed patch cable between the client system and the wall jack.

You have just connected four new computer systems to an Ethernet switch using spare patch cables. After the installation, only three systems are able to access the network. You verify all client network settings and replace the network card in the failed system. The client is still unable to access the network. Which of the following might you suspect is the real cause of the problem? Failed patch cable Failed switch Incorrect LAN protocol Incorrect routing table Faulty IP stack

Failed patch cable.

Users are complaining that sometimes network communications are slow. You use a protocol analyzer and find that packets are being corrupted as they pass through a switch. You also notice analyzer and find that packets are being corrupted as they pass through a switch. You also notice that this only seems to happen when the elevator is running. What should you do? Install a dedicated power circuit for the switch. Install shielded cables near the elevator. Add a UPS system to the switch. Add a dedicated A/C unit to the switch closet.

Install shielded cables near the elevator.

You have a network connected using a physical bus topology. One of the cables that connects a workstation to the bus breaks. Which of the following best describes what effect this will have on network communications? Devices on one side of the break will be able to communicate with each other; devices on the other side of the break will be able to communicate with each other. All devices except the device connected with the drop cable will be able to communicate. All devices will be able to communicate. Devices on one side of the break will be able to communicate with each other; devices on the other side will not be able to communicate. No devices will be able to communicate.

No devices will be able to communicate.

You've connected a cable certifier to an RJ45 wall jack and the output shown below is displayed You've connected a cable certifier to an RJ45 wall jack and the output shown below is displayed on the device. What does this output indicate? (Select two.) Pin 6 is open. The cable is functioning correctly. Pin 6 is shorted. Pin 4 is shorted. Pin 4 is open. Pins 4 and 6 are crossed-over. Pins 4 and 6 are straight-through.

Pin 6 is open. Pin 4 is open.

You have a network connected using a full physical mesh topology. The link between device A and device B is broken. Which of the following best describes what affect this will have on the network device. Device A will not be able to communicate with any other device. Device A will be able to communicate with any device except for device B. Device A will be able to communicate with all other devices. No devices will be able to communicate with any other device.

Device A will be able to communicate with all other devices.
