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 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 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.

|
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 network communications?
•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.

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 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

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 patch 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

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 collisions?
•Incorrect duplex settings
•Adapter controller card failure
•Faulty switch
•Faulty network card
•PCI slot failure
|
Faulty network card

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?
•Reinstall the network card drivers on the sales server.
•Replace the network card in the user’s computer.
•Replace the Ethernet switch in the sales department.
•Replace the network card in the sales server.
|
Replace the network card in the user’s computer.

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
Cat 6e cable to connect the wiring closet to the shipping building.
Which of the following should you include in your plan?
•Shielded twisted pair
•Half-duplex
•Repeater
•Spanning tree
|
Repeater
