Fundamentals of Networking 4.4.10 Practice Questions

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?

No devices will be able to communicate.

You are creating an Ethernet network for your company. The shipping department is located in a different building that is located 150 meters from the main wiring closet. You connect a single Cat6e cable to connect the wiring closet to the shipping building. Which of the following are you most likely to experience?

Repeater

Angela is the network administrator for a rapidly growing company with a 100BaseT network. Users have recently complained about slow file transfers. In a check of network traffic, Angela discovers a high number of collisions. Which connectivity device would best reduce the number of collisions and provide future growth?

Switch

You have a network connected using a physical star topology. One of the drop cables that connects a workstation has been removed. Which of the following best describes what effect this will have on network communications?

All devices except the device 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 Cat 5e patch cable that stretches from the network printer to the upgraded switch. What is the impact on the network?

All network nodes EXCEPT the printer will be available.

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 effect this will have on network communications?

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

You are moving a client to a new location within an Ethernet network. Previous to the move, the client system did not have any difficulty accessing the network. During the relocation, you attach a patch cable 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 can still not connect. Which of the following might you suspect as the problem?

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.

Upon conducting a visual inspection of the server room, you see that a switch displays LED collision lights that are continually lit. You check the LED on the corresponding workstation and see that it is flashing rapidly even though it is not sending or receiving network traffic at that time. What is the cause of the network collision?

Faulty network card

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 that this only seems to happen when the elevator is running. What should you do?

Install shielded cables near the elevator.

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 4 & 6 are open.

A user from the Sales department calls to report that he is experiencing problems connecting to the Sales file server. All users in the Sales department connect to the Sales server through a single Ethernet switch. No other users have reported problems connecting to the Sales server. Which of the following troubleshooting actions are you most likely to perform first?

Replace the network card in the user's computer
