NEW QUESTION # 815
Which of the following 802.11 Wi-Fi protocols utilizes the 5.0GHz frequency and has the BEST speed and reception?

  • A. 802.11b/g/n
  • B. 802.11n
  • C. 802.11a
  • D. 802.11 ax

Answer: D

Explanation:
802.11 ax is a wireless networking protocol that utilizes the 5.0GHz frequency and has the best speed and reception among the options given. 802.11 ax offers higher data rates, lower latency, increased capacity, and improved power efficiency than previous protocols. It is also known as Wi-Fi 6 or High Efficiency Wireless (HEW). 802.11a also uses the 5.0GHz frequency, but it is an older protocol that has lower speed and reception than 802.11 ax. 802.11b/g/n use the 2.4GHz frequency, which is more crowded and prone to interference than the 5.0GHz frequency. 802.11n can use both frequencies, but it is also slower and less efficient than 802.11 ax.

NEW QUESTION # 816
A technician is troubleshooting a laptop that displays a blank screen when the user turns it on. The technician shines a flashlight into the LCD and sees a faint image. Which of the following is the most likely cause of the issue?

  • A. Incompatible video driver
  • B. Incorrect input source
  • C. Burned-out bulb
  • D. Defective inverter

Answer: D

Explanation:
Explanation
The most likely cause of the issue is a defective inverter. An inverter is a device that converts the direct current (DC) power from the laptop battery or adapter to the alternating current (AC) power that the LCD backlight bulb needs. The backlight bulb is a fluorescent lamp that illuminates the LCD screen and makes the image visible. If the inverter is defective, it may not provide enough power to the backlight bulb, or it may stop working intermittently. This can result in a dim, dark, or blank screen, even though the LCD panel is still functioning and displaying a faint image.
To troubleshoot a defective inverter, the technician can follow these steps:
Connect an external monitor to the laptop and check if the image is displayed normally. If the external monitor works fine, it means that the laptop video card and driver are not the cause of the issue.
Shine a flashlight into the LCD screen and look for a faint image. If the image is visible, it means that the LCD panel is not the cause of the issue.
Check the inverter cable and connector for any damage, loose connection, or corrosion. The inverter cable is a thin wire that runs from the laptop motherboard to the inverter board, which is usually located at the bottom of the LCD screen. The inverter connector is a small plug that connects the inverter cable to the inverter board. The technician can try to reseat the inverter cable and connector, or replace them if they are faulty.
Check the inverter board for any damage, burn marks, or blown fuses. The inverter board is a small circuit board that contains the inverter and other components. The technician can try to test the inverter board with a multimeter, or replace it if it is defective.

NEW QUESTION # 817
A technician is setting up a video-editing workstation and the operating system is already installed on an internal M.2 drive.
The new workstation must meet the following requirements:
. Be able to edit files at the fastest speed
. Allow for disk failure without any downtime
Have 2TB of usable space
. Ensure the most robust fault tolerance
INSTRUCTIONS
Use the drop-down menus to select the appropriate RAID level, drive types, and drive sizes based on the requirements above. For each drive type that is selected, a corresponding drive size must also be selected.

Answer:

Explanation:

Explanation:
Based on the requirements, the best option for the video-editing workstation is to use RAID 10 with four SATA SSDs of 1TB each. This configuration will meet the following requirements:
* Be able to edit files at the fastest speed: RAID 10 combines the advantages of RAID 0 and RAID 1, which are striping and mirroring, respectively. Striping can increase the data transfer rate by using multiple disks in parallel, while mirroring can provide redundancy and reliability by duplicating the data on another set of disks. SATA SSDs are also faster than HDDs or SSHDs, as they use flash memory instead of spinning disks, and they can offer lower latency, higher IOPS, and less noise and heat.
* Allow for disk failure without any downtime: RAID 10 can withstand up to two disk failures, as long as they are not in the same mirrored pair. If one disk fails, the data can be read from or written to the other disk in the same pair, without affecting the performance or availability of the array. The failed disk can be replaced and rebuilt without interrupting the operation of the workstation.
* Have 2TB of usable space: RAID 10 uses half of the total disk capacity for mirroring, so the usable space is equal to the size of two disks. By using four SATA SSDs of 1TB each, the total disk capacity is
4TB, and the usable space is 2TB, which meets the requirement.
* Ensure the most robust fault tolerance: RAID 10 offers the highest level of fault tolerance among the standard RAID levels, as it can survive multiple disk failures and provide fast recovery. RAID 10 also has a low overhead, as it does not use parity or checksums, which can slow down the write performance or increase the complexity of the array.
Therefore, the technician should select the following options from the drop-down menus:
* RAID level: RAID 10
* Drive type 1: SATA SSD
* Drive size 1: 1TB
* Drive type 2: SATA SSD
* Drive size 2: 1TB
* Drive type 3: SATA SSD
* Drive size 3: 1TB
* Drive type 4: SATA SSD
* Drive size 4: 1TB
* Drive type 5: SATA SSD
* Drive size 5: 1TB


NEW QUESTION # 818
A user reports that a printer is leaving streaks on printed pages. The paper type and the toner have been replaced. Which of the following should the technician check NEXT to resolve the issue?

  • A. Paper tray
  • B. Fuser
  • C. System board
  • D. Memory

Answer: B

Explanation:
Explanation
This is because the fuser is the part of the printer that heats and melts the toner onto the paper. If the fuser is defective or dirty, it can cause streaks or smudges on printed pages. The system board and the memory are not related to the quality of the print output. The paper tray may cause paper jams or misfeeds, but not streaks on the paper.
