What provides the illuminattion for LCD monitors?
- A.
Inverters
- B.
LCD panel
- C.
Backlights
- D.
Lamp
Correct Answer
C. BacklightsExplanation
Backlights provide the illumination for LCD monitors. LCD panels themselves do not emit light, so they require a separate light source to display images. Backlights are typically placed behind the LCD panel and provide uniform illumination across the screen, allowing the liquid crystals in the panel to manipulate the light and create the images that we see. Inverters are used to control the brightness of the backlights, while lamps are a type of backlight technology.Rate this question:

How should you remove a modular drive?
- A.
Use the Hardware Removal Tool in the System tray
- B.
Shut down, remove the drive, and power back on
- C.
Simply remove the drive with no additional actions
- D.
Use Device Manager to uninstall the device
Correct Answer
A. Use the Hardware Removal Tool in the System trayExplanation
To remove a modular drive, it is recommended to use the Hardware Removal Tool in the System tray. This tool ensures that the drive is safely ejected and all necessary processes are completed before removal. Simply removing the drive without using the tool may result in data loss or damage to the drive. Shutting down, removing the drive, and powering back on is not the recommended method as it may lead to improper removal and potential system errors. Using Device Manager to uninstall the device is also not the correct approach as it is meant for uninstalling software components, not physical drives.Rate this question:

Maria's laptop's fan is making a high-pitched whine and doesn't seem to be spinning well. What's a fix for this issue?
- A.
Move the computer to a warmer room
- B.
Put the laptop on a soft surface, such as a pillow
- C.
Replace the fan
- D.
Take the computer to the repair shop
Correct Answer
C. Replace the fanExplanation
The correct answer is to replace the fan. If the laptop's fan is making a high-pitched whine and not spinning well, it is likely that the fan is faulty or damaged. Moving the computer to a warmer room or putting it on a soft surface will not fix the issue with the fan. Taking the computer to a repair shop might be an option, but the most effective solution would be to replace the fan altogether.Rate this question:

What unique identifier is assigned to every NIC?
- A.
IP address
- B.
MAC address
- C.
Packet address
- D.
ZIP address
Correct Answer
B. MAC addressExplanation
A unique identifier assigned to every NIC is a MAC address. This address is a hardware address that is assigned to the network interface card (NIC) of a device. It is used to uniquely identify the device on a network. Unlike an IP address, which can change, the MAC address is permanent and cannot be easily altered. The MAC address is used for communication at the data link layer of the network protocol stack.Rate this question:

Everything worked fine on your 100BaseT star bus topology network yesterday, but today, no on can connect to the server. The server seems to be in good running order. Which of the following is the most likely problem?
- A.
A switch is malfunctioning
- B.
Someone changed all the passwords for server access
- C.
Someone's T connector has come loose on the bus
- D.
The server's cable is wired as TIA/EIA 568A, and all the others are wired as TIA/EIA 568B
Correct Answer
A. A switch is malfunctioningExplanation
A switch is malfunctioning. If everything was working fine on the network yesterday but no one can connect to the server today, it suggests that there might be an issue with the switch. The switch is responsible for connecting devices on a network and if it malfunctions, it can cause connectivity problems for all the devices connected to it. Therefore, a malfunctioning switch is the most likely problem in this scenario.Rate this question:

Which encryption method used on wireless networks is the most secure?
- A.
WEP
- B.
Wi-Fi
- C.
WINS
- D.
WPA2
Correct Answer
D. WPA2Explanation
WPA2 is the most secure encryption method used on wireless networks. WEP (Wired Equivalent Privacy) is an outdated and easily crackable encryption method, while Wi-Fi and WINS (Windows Internet Name Service) are not encryption methods at all. WPA2 (Wi-Fi Protected Access 2) is currently the strongest encryption protocol available for wireless networks, providing strong security measures such as AES encryption and authentication protocols to protect data transmission.Rate this question:

Which wireless networking standard uses the MIMO (multiple in / multiple out)?
- A.
802.11
- B.
802.11n
- C.
802.11b
- D.
802.11g
Correct Answer
B. 802.11nExplanation
802.11n is the correct answer because it is a wireless networking standard that uses MIMO (multiple in / multiple out) technology. MIMO allows for multiple antennas to transmit and receive data simultaneously, resulting in improved signal strength, increased data throughput, and better overall performance compared to previous standards such as 802.11b and 802.11g. The other options, 802.11, 802.11b, and 802.11g, do not specifically mention MIMO technology.Rate this question:

To enable two devices to communicate wirelessley in ad hoc mode, what configuration is required?
- A.
Both devices need to have the same IP address
- B.
Both devices need to have the same SSID
- C.
Both devices need to plug into the same WAP
- D.
No additional configuration is requred
Correct Answer
B. Both devices need to have the same SSIDExplanation
For two devices to communicate wirelessly in ad hoc mode, they need to have the same SSID (Service Set Identifier). The SSID is a unique identifier that allows devices to connect to the same wireless network. By having the same SSID, the devices can recognize and communicate with each other, forming a direct connection without the need for a central access point or router. This allows for a direct peer-to-peer connection between the devices, enabling wireless communication.Rate this question:

Which of the following offers a fast connection for an external modem?
- A.
CNR
- B.
PCI
- C.
Serial Port
- D.
USB
Correct Answer
D. USBExplanation
USB offers a fast connection for an external modem. USB (Universal Serial Bus) is a widely used interface for connecting devices to a computer. It provides high-speed data transfer rates, making it suitable for connecting peripherals such as modems. CNR (Communication and Networking Riser) is a slot on the motherboard for audio and network cards, not specifically designed for modems. PCI (Peripheral Component Interconnect) is a bus for connecting internal hardware components, not external modems. Serial Port is a slower connection compared to USB and is not typically used for modems anymore.Rate this question:

A new client lives in a rural area, outside the connectivity radius of the local cable company and definitely more than 20,000 feet away from the nearest switching center for the phone company. Which Internet option offers him the best performance?
- A.
Cable
- B.
Dial-Up
- C.
DSL
- D.
Satelite
Correct Answer
D. SateliteExplanation
In this scenario, where the client lives in a rural area and is far away from the nearest switching center, the best internet option for them would be satellite internet. Satellite internet does not require physical infrastructure like cables or phone lines, making it accessible even in remote areas. It provides a reliable and high-speed internet connection by transmitting data through satellites in space. Therefore, satellite internet would offer the best performance for the client in this situation.Rate this question:

What kind of malware changes its signature to avoid detection?
- A.
Polymorph
- B.
Spyware
- C.
Trojan
- D.
Worm
Correct Answer
A. PolymorphExplanation
Polymorph is a type of malware that changes its signature to avoid detection. Unlike other types of malware that have a fixed signature, polymorph malware constantly modifies its code and appearance, making it difficult for antivirus programs to recognize and detect. By changing its signature, polymorph malware can evade detection and continue to infect systems without being detected by traditional security measures. This allows the malware to remain undetected and potentially cause significant damage to the targeted system.Rate this question:
