Question

You, as a network engineer, have recently established a network connection for three separate department buildings in a university. one of the departments has complained that the signal strength it receives is not the same as the signal strength the other two buildings receive. which of the following will you use in this scenario?

a. NIU
b. Line drivers
c. DTE
d. CSU/DSU

Answer 1

To troubleshoot the issue of unequal signal strength in the university's network connection, it is likely that you would use a Network Interface Unit (NIU). A NIU is a device that connects a computer or other device to a network and allows it to communicate with other devices on the network. In this scenario, the NIU would be used to measure the signal strength of the network connection for the department that is experiencing problems, and compare it to the signal strength of the connections for the other two buildings. By doing this, you would be able to determine whether the issue is with the department's connection or with the overall network, and take appropriate action to fix the problem.

The other options listed in the question are not relevant to this scenario. Line drivers are used to boost the signal strength of a network connection over long distances, but in this case, the signal strength issue is only affecting one department, so line drivers would not be necessary. DTE and CSU/DSU are both types of devices used in networking, but they are not directly related to measuring or troubleshooting signal strength.

Answer 2

In this scenario, you could use a Network Interface Unit (NIU) to improve the signal strength received by the department with weaker signal.

An NIU is a device that connects a computer or other device to a network. It typically consists of a network interface card (NIC) and a transceiver that converts the data signals from the NIC into a format that can be transmitted over the network.

One of the main functions of an NIU is to amplify the network signal, which can improve its strength and reliability. This can be useful in situations where the signal strength is weaker in certain areas, such as the department building in the university scenario described in the question. By using an NIU, you can boost the signal strength and improve the department's network connectivity.

In contrast, a line driver is a device that is used to extend the length of a network cable by amplifying the signal. It is not typically used to improve the signal strength within a network, as an NIU would be more appropriate for that purpose.

A Data Terminal Equipment (DTE) is a device that terminates a network connection on the user side, such as a computer or printer. It is not typically used to improve the signal strength within a network, as an NIU would be more appropriate for that purpose.

A Channel Service Unit/Data Service Unit (CSU/DSU) is a device that is used to connect a computer or network to a digital circuit, such as a T1 or E1 line. It is not typically used to improve the signal strength within a network, as an NIU would be more appropriate for that purpose.
