2.5 Weekly Assessment

Labs (4)

> You are a network technician for a small corporate network. The company owner has asked you to connect a new workstation to the network while a new employee is in an orientation meeting. In this lab, your task is to: Connect the workstation in Office 1 to the Ethernet local area network using twisted pair cable. Confirm that the Office 1 workstation is connected to the local network and the internet. > You are working on a small network. You have just signed up for cable internet access for the network. The cable company has installed the line in your home and given you a preconfigured modem for your network. In this lab, your task is to: Connect the components to make the internet connection.Add the cable modem to the Workspace.Connect the modem to the WAN connection using the cable with the least amount of signal loss.Connect the computer to the cable modem using a 10/100 Mbps Ethernet connection.Use the AC to DC power adapter to plug in the modem. Use the Network and Sharing Center in Windows to confirm that the Home-PC computer is properly connected to the internet. > You are a network technician for a small corporate network. Today you moved an unused workstation to the IT Administration office, and now you need to connect the computer to the Ethernet local area network and the internet. In this lab, your task is to connect the workstation to the wired network as follows: In the Networking Closet, use the appropriate twisted pair cable to make a connection between the patch panel and switch.Use port IT Adm on the patch panel.Use port 5 on the switch. In the IT Administration office:Connect the ITAdmin workstation to the local area network using the appropriate twisted pair cable.Configure ITAdmin to obtain IP and DNS addresses automatically from the server on the local network.Use the Network and Sharing Center to confirm that the workstation is properly connected to the local area network and the internet. > You work as the IT administrator for a growing corporate network. You are in the process of creating an iSCSI storage area network (SAN) on the CorpiSCSI server. The server is currently connected to the network using an Ethernet cable. To increase the server's performance, you have decided to replace the existing Ethernet connection with a fiber optic connection. In this lab, your task is to complete the following: Connect the CorpiSCSI server to the switch using the appropriate fiber optic cable.Examine the port types on the switch.Examine the server's fiber optic NIC. When connecting the server, use the color coding on the end of the fiber optic cable to identify the Tx and Rx connection ends.Connector A (red) is Tx.Connector B (black) is Rx. Remove the server's previous Ethernet network connection and place the Ethernet cable on the Shelf. Verify that the server is connected to the network through the fiber optic connection.

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 use a single Cat6e cable to connect the wiring closet to the shipping building. Which of the following conditions are you most likely to experience?

Attenuation

Which of the following cable types often includes a solid plastic core that keeps the twisted pairs separated?

Cat 6

You manage a network that uses 1000BaseT Ethernet. You find that one device communicates on the network at only 100 Mbps. Which tool should you use to test the drop cable and the connection to the network?

Certifier

You have decided to implement Gigabit Ethernet on your network. Each switch port is connected to a single device. Following the installation, you find one device connected to a switch that is only running at 100 Mbps. Which of the following are likely causes?

Crosstalk

Which of the following describes the point where the service provider's responsibility to install and maintain wiring and equipment ends, and the customer's responsibility begins?

Demarc

You have just signed up for a broadband home internet service that uses coaxial cable. Which connector type will you most likely use?

F-type

Which recommendation should you follow while using 110 blocks for connecting Cat 5 and higher data cables?

Keep wire pairs twisted up to within one-half of an inch of the connector.

You want to measure the voltage, amps, and ohms of various devices. Which tool should you use?

Multimeter

You are working with an existing fiber optic installation in your building. You want to know the length of each cable that runs through the walls. Which tool should you use?

OTDR

You are adding new wires in your building for some new offices. The building has a false ceiling that holds the lights and provides an air path for heating and air conditioning. You would like to run your Ethernet cables in this area. Which type of cable must you use?

Plenum rated cable

What tool should you use to extend network services beyond the demarc?

Punch down tool

Which of the following connectors is used with Ethernet 100BaseT networks?

RJ45

Which of the following connectors is used with fiber optic cables and requires that you use a twisting motion to connect it?

ST

You use Cat5e twisted pair cable on your network. Cables are routed through walls and the ceiling. A user puts a screw in the wall to hang a picture and pierces the cable so that a signal sent on pin 1 arrives on the cable connected to pin 7. Which term describes this condition?

Short circuit

Which type of optical fiber is normally used to connect two buildings that are several kilometers apart?

Single-mode

Why might you use an RJ11 connector?

You want to connect your computer to the internet with a DSL modem.
