CompTIA 220-1101 Online Questions & Answers

• Question 301:

  A technician is building a video production workstation that will consist of two high-end GPUs The technician is reusing an existing ATX case. Which of the following should the technician select as the MOST appropriate power supply type?

  A. 400W external power supply
  B. 2x 600W redundant power supplies
  C. 1.200W modular power supply
  D. 1.5O0W uninterruptible power supply
  C. 1.200W modular power supply

  ---

  Explanation

  A video production workstation that will consist of two high-end GPUs will require a lot of power and a modular power supply. A modular power supply allows the technician to connect only the cables that are needed for the components, which reduces clutter and improves airflow. A 1,200W power supply should be enough to power the two GPUs and other components, but the exact wattage depends on the specifications of the GPUs and other components. A 400W external power supply is not enough to power the workstation and may not be compatible with the ATX case. Two 600W redundant power supplies are unnecessary and may not fit in the ATX case. A 1,500W uninterruptible power supply (UPS) is a device that provides backup power in case of a power outage, but it is not a replacement for a power supply unit (PSU).

• Question 303:

  A technician is troubleshooting a projector that will not display any Images. The technician has verified the computer output and cable are providing a good video signal. Which of the following should the technician do NEXT?

  A. Calibrate the image.
  B. Replace the bulb.
  C. Test the output resolution.
  D. Clean the fans.
  C. Test the output resolution.

  ---

  Explanation

  The MOST efficient next step the technician should do is to test the output resolution1. The issue of a projector that will not display any images could be related to the output resolution1. If the output resolution is not compatible with the projector, the projector will not display any images1. Calibrating the image, replacing the bulb, or cleaning the fans may not be effective1. If a projector is not displaying any images despite verifying that the computer output and cable are providing a good video signal, the technician should test the output resolution. The output resolution of the computer may not be compatible with the projector, which can cause the projector to not display any images.

• Question 304:

  A new employee has been issued a company laptop. The employee requests an accessory with a single power source that has wired network connectivity and supports a keyboard, mouse, speakers, and dual monitors. Which of the following accessories should the systems administrator deploy to BEST meet the new user's needs?

  A. PoE switch
  B. USB-C hub with power delivery
  C. Docking station with DisplayPort
  D. KVM switch with audio
  C. Docking station with DisplayPort

  ---

  Explanation

  A docking station is a hardware accessory that allows laptops to connect to multiple peripherals and devices with a single connection. A docking station with DisplayPort would provide the necessary connectivity for the dual monitors, and it can also support the required peripherals such as the keyboard, mouse, and speakers. In addition, it will provide a wired network connectivity for faster and more reliable network access.

• Question 305:

• Question 307:

  Which of the following display characteristics would be most important to ensure screen images appear the same as printed output?

  A. Color gamut
  B. Pixel density
  C. Refresh rate
  D. Resolution
  A. Color gamut

  ---

  Explanation

  Color gamut refers to the range of colors a display can accurately reproduce. For tasks like graphic design or photo editing, ensuring the screen's colors match the printed output is critical. Monitors with wide and accurate color gamuts (e.g., Adobe RGB) are preferred for these applications.

  Option B (Pixel density): Incorrect. Pixel density affects image sharpness, not color accuracy.

  Option C (Refresh rate): Incorrect. Refresh rate impacts motion smoothness but is unrelated to color matching.

  Option D (Resolution): Incorrect. Resolution determines clarity and detail but does not influence color accuracy.

• Question 308:

  A user is no longer able to browse the Internet after returning from vacation. The user is able to log in and navigate to the local intranet, but not to any outside sites. A technician pings a well-known website by name but gets no reply. The technician then pings its IP address and gets a reply.

• Question 309:

  A company would like to take advantage of the cost savings of cloud computing by only paying for the resources used. Which of the following will BEST address this need?

  A. Shared resources
  B. Rapid elasticity
  C. Metered utilization
  D. High availability
  C. Metered utilization

  ---

  Explanation

  Metered utilization is a cloud feature that allows cloud providers to charge customers based on their actual consumption of resources, such as CPU time, storage space, bandwidth, or transactions.This enables customers to pay only for the

  resources they use, rather than a fixed or flat rate, which can reduce costs and increase efficiency. Metered utilization can also provide more transparency and accountability for both cloud providers and customers, as they can track and

  monitor their resource usage and billing.
