The screen can be recalibrated using the tablet's settings or a utility program. The screen is not physically damaged, as there is no visible crack or break. The screen rotation is not related to the cursor drift, as it only affects the orientation of the display. The touch-pen battery is not relevant, as the cursor drift occurs even without using the pen.

NEW QUESTION # 127
A customer purchased an active touch pen for a tablet PC. After the customer used the pen for a few days, it stopped working. Which of the following is most likely causing the issue?
- A. The pen batteries need recharging.
- B. The pen software is out of date.
- C. Software updates disabled the pen.
- D. The tablet screen is scratched.
Answer: A
Explanation:
Explanation
The most likely answer is C. The pen batteries need recharging.
An active touch pen is a stylus that uses a battery to power features such as pressure sensitivity, buttons, or Bluetooth connectivity. If the pen batteries are low or depleted, the pen may stop working or become inaccurate1. To fix this issue, you should recharge the pen batteries using the provided charger or cable, or replace them with new ones if they are not rechargeable1.
The other options are less likely to cause the issue. A scratched tablet screen may affect the touch sensitivity, but it should not affect the pen functionality. The pen software may need updating to improve performance or compatibility, but it should not stop the pen from working altogether. Software updates may disable the pen if they change the settings or drivers, but this can be fixed by re-enabling the pen or reinstalling the drivers2.

Every time a user tries to print a multipage document, the user is unable to print on both sides of the page.
Which of the following settings will most likely resolve this issue?
- A. Orientation
- B. Print tray
- C. Quality
- D. Duplex
Answer: D
Explanation:
Explanation
The correct answer is B. Duplex.
Duplex printing is the process of printing on both sides of a sheet of paper automatically or manually. Duplex printing can save paper, reduce clutter, and create professional-looking documents. To print on both sides of the paper, the printer must support duplex printing or the user must manually reinsert the pages to print the second side.
Orientation is the direction in which the paper is printed, either portrait (vertical) or landscape (horizontal).
Orientation does not affect the ability to print on both sides of the paper.
Quality is the resolution or sharpness of the printed image, measured in dots per inch (dpi). Quality does not affect the ability to print on both sides of the paper.
Print tray is the part of the printer that holds and feeds the paper into the printer. Print tray does not affect the ability to print on both sides of the paper.
To enable duplex printing on a Windows PC, follow these steps1:
Open the document for printing, then select File > Print.
In Settings, select Manually Print on Both Sides, then Print.
Follow the instructions on the screen to flip and reinsert the pages.
To enable duplex printing on a Mac, follow these steps2:
Open the document for printing, then select File > Print.
In Layout, select Two-Sided, then Long-Edge binding or Short-Edge binding.
Click Print.

It is significantly faster than SATA SSDs and SAS hard drives, making it ideal for users who need fast storage for their laptop. NVMe SSDs also have lower latency and higher bandwidth than traditional hard drives, making them well-suited for data-intensive tasks such as video editing, gaming, and running multiple applications simultaneously. Additionally, NVMe offers more reliable data reliability than traditional hard drives, and is less susceptible to performance degradation over time.
NEW QUESTION # 139
An administrator notices that on an intermittent basis the virtual machines are running slowly. The virtual machines are correctly sized, and the hardware has enough free resources to cope with demand Which of the following is most likely the cause?
- A. The physical servers are not able to draw enough power
- B. The physical servers do not have enough network bandwidth.
- C. The physical servers are contending for resources
- D. The physical servers are throttling due to overheating
Answer: D
Explanation:
Explanation
The physical servers are throttling due to overheating. This means that the servers are reducing their performance to prevent damage from excessive heat. This can cause the virtual machines to run slowly, as they depend on the physical servers' resources. To avoid this, the servers need adequate cooling and ventilation, as well as monitoring of their temperature and fan speed. According to the CompTIA Core1 objectives, one of the environmental factors that can affect system performance is overheating. A research paper on thermal management of servers also states that overheating can lead to performance degradation, reliability issues, and energy inefficiency.
