Mod 6 Mindtap Practice Test

A client has complained to you about low signal strength in his office. You want to ensure that the issue is resolved, and for that purpose, you plan to place the Wi-Fi client very close to the AP (access point). What level of RSSI (received signal strength indicator) rating will you check to fix this issue? -30 dBm with an excellent rating -50 dBm with a good rating -80 dBm with a not good rating -70 dBm with an acceptable rating

-30 dBm with an excellent rating is typically achieved when the client is very close to the AP, so the RSSI level should at least be -30 dBm in this case.

What is the frequency range for cellular communication? 1850 MHz-1990 MHz 300 GHz-300,000 GHz 2.4 GHz-2.4835 GHz 5.1 GHz-5.8 GHz

1850 MHz-1990 MHz

You have been contracted to install a wireless network connection at Vice City Public School. The school management has requested you to install the latest available Wi-Fi technology for the students. Which of the following frequencies will you use to establish the connection in this scenario? 1850 MHz-1990 MHz 2.446 GHz-2.454 GHz 5.1 GHz-5.8 GHz 300 GHz-300,000 GHz

5.1 GHz-5.8 GHz Wi-Fi 802.11a/n/ac/ax uses this frequency, and it is relevant in this scenario.

The head office of Vojks Telecommunications runs on a standard WLAN network, and it has hired Jim as a network administrator to upgrade its network to faster standards. On inspection, Jim realizes that a throughput of 50 Mbps should be sufficient for the smooth functioning of the office. The only request Vojks has made to Jim is to ensure that the older computers still have wireless access during the upgrade. Analyze which of the following standards Jim should use in this scenario. 802.11g 802.11b 802.11n 802.11a

802.11g was designed to be just as affordable as 802.11b while increasing its maximum theoretical throughput with different data modulation techniques. 802.11g benefits from being compatible with 802.11b networks that allow older computers to have wireless access during an upgrade.

Dwight is a fresher who has been hired as an assistant to the head network administrator. Which of the following 802.11 wireless standards should Dwight have an understanding of so that he can assist his senior in setting up a wireless standard that has a theoretical throughput of 600 Mbps? 802.11a 802.11b 802.11ax 802.11n

802.11n

Tyler has plans of setting up a cellular network distribution plant for which he has contacted you to act as a service manager. Your first job as a service manager is to document the necessary frequency range under which this 800 band will be operational. Which of the following frequencies in the wireless spectrum will you use to successfully enable this connection? 824 MHz-896 MHz 2.4 GHz-2.4835 GHz 5.1 GHz-5.8 GHz 1850 MHz-1990 MHz

As the requirement is of an 800-band cellular technology, the network will operate in the frequency range of 824 MHz-896 MHz.

Howard has recently installed a network connection for a workstation where he has made network connections accessible through both wired and wireless connections. Before finishing the installation, he wants to check whether the computer is making conflicting attempts to communicate with the network through both types of connections. After inspection, he realizes that the computer is indeed making conflicting attempts. Which of the following steps will help Howard in resolving the issue? He can resolve the issue by disabling the Wi-Fi adapter or by unplugging the Ethernet cable. He can resolve the issue by placing the AP in a high spot for best signal transmission to clients. He can resolve the issue by installing a newer Wi-Fi standard. He can resolve the issue by updating to a NIC or access point's firmware.

He can resolve the issue by disabling the Wi-Fi adapter or by unplugging the Ethernet cable.

As a network engineer, you have installed a wireless connection in a newly constructed office floor for Black & White Communications. The CEO's office files a complaint about slow data transmission with the IT department. The IT department gets in touch with you to fix this error. On inspection, you realize that the problem is primarily because of large obstacles like walls and ceilings because of which the wave bounces back to its source. What of the following phenomena will you state as a cause of this error while reporting to the IT department? Reflection Attenuation Refraction Interference

Reflection occurs when a wave encounters an obstacle and reflects, or bounces back, toward its source. A wireless signal will bounce off objects whose surface dimensions are large compared with the signal's average wavelength.

You are the proprietor of an export business. Currently, the wireless network in your office is using the WEP (Wired Equivalent Privacy) standard. It offers two forms of authentication: OSA (Open System Authentication) and SKA (Shared Key Authentication). However, neither of them is secure. Your requirement is of an authorization service that provides a central authentication point for wireless, mobile, and remote users. Which of the following will you use in such a scenario? WPA2 WPA WPA-Enterprise or WPA2-Enterprise WPA-PSK or WPA2-PSK

WPA-Enterprise or WPA2-Enterprise uses RADIUS (Remote Authentication Dial-In User Service), which is an open-source authentication and authorization service. A RADIUS server can be used to offer a central authentication point for wireless, mobile, and remote users.

Which of the following security threats requires a PIN (personal identification number) to access an AP's settings or to associate a new device with a network? WPS attack WPA attack War driving War chalking

WPS attack WPS (Wi-Fi Protected Setup) requires a PIN (personal identification number) to access an AP's settings or to associate a new device with a network.
