While implementing a non-carrier-grade wireless backhaul, a technician notices the current channel selection is extremely polluted with various RF signals. Upon performing a spectral analysis, the technician discovers a channel containing almost no RF pollution. Unfortunately, the technician is unable to select that channel. Which of the following is the MOST likely reason for this issue?
Correct Answer: A
220-1101 Exam Question 507
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?
Correct Answer: C
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.

220-1101 Exam Question 508
An end user needs to upgrade the hard drive on a laptop and wants one that is fast and shock resistant. Which of the following is the BEST option for this end user?
Correct Answer: D
Explanation A non-volatile memory express (NVMe) solid state drive (SSD) is the best option for an end user who wants to upgrade the hard drive on a laptop and wants one that is fast and shock resistant.NVMe SSDs use flash memory and PCIe interface to achieve high performance and low latency.SSDs are also more shock resistant than hard disk drives (HDDs) because they have no moving parts.Hybrid HDD/SSD combines both technologies but does not offer the same speed or capacity as pure SSDs.A 5,400rpm HDD or a 7,200rpm HDD are slower and less shock resistant than SSDs
220-1101 Exam Question 509
A user needs to upgrade a PC in order to run the latest 3-D design software. Which of the following components should the user upgrade to best meet this requirement?
Correct Answer: D
Explanation The correct answer is D. Graphics card.A graphics card is a component that handles the processing and rendering of 3D graphics on a PC. A graphics card can significantly improve the performance and quality of 3D design software, as it can handle complex calculations and display high-resolution images faster than the CPU. A graphics card can also support features such as ray tracing, anti-aliasing, and texture mapping, which can enhance the realism and detail of 3D models. A: Motherboard. This is not a correct answer. A motherboard is a component that connects and communicates with all the other components in a PC. A motherboard does not directly affect the performance or quality of 3D design software, unless it is incompatible or outdated with the other components. B: CPU. This is not a correct answer. A CPU is a component that executes instructions and calculations for various programs on a PC. A CPU can affect the performance and quality of 3D design software, but not as much as a graphics card. A CPU is more important for tasks such as compiling, encoding, or multitasking, which are not specific to 3D design. C; Power supply. This is not a correct answer. A power supply is a component that converts AC power from the wall outlet to DC power for the PC components. A power supply does not directly affect the performance or quality of 3D design software, unless it is insufficient or faulty to provide enough power for the other components. E: Memory. This is not a correct answer. Memory is a component that stores data temporarily for fast access by the CPU and other components. Memory can affect the performance and quality of 3D design software, but not as much as a graphics card. Memory is more important for tasks such as loading, saving, or switching between programs, which are not specific to 3D design.

220-1101 Exam Question 510
After a required operating system upgrade on a mobile deuce, a user's external monitor no longer works. Which of the following should a technician do to fix this issue?
Correct Answer: A
The correct answer is A. Install the latest graphics drivers. The most likely cause of the external monitor not working after an operating system upgrade is that the graphics drivers are incompatible with the new version. Installing the latest graphics drivers from the manufacturer's website or using Windows Update can resolve this issue. Replacing the monitor, restoring the operating system to the previous version, or reseating the external video adapter are not effective solutions for this problem.
