CompTIA 220-1101 Online Questions & Answers

• Question 391:

  A user is experiencing multiple issues with an in-place upgrade of a laptop's operating system. The built-in camera is unresponsive, and the user is unable to pair the device with any Bluetooth accessories.

  Which of the following ate most likely causing three issues? (Select two).

  A. Incorrect configuration of the settings
  B. OS and device version incompatibility
  C. Disabled settings following the upgrade
  D. Full storage
  E. Outdated drivers
  F. Corrupted registry entries
  C. Disabled settings following the upgrade
  E. Outdated drivers

  ---

  Explanation

  Outdated drivers: Device functionality issues after an OS upgrade are often caused by incompatible or outdated drivers.

  Disabled settings: Some features may be disabled during the upgrade process, requiring re-enablement.

  Why Not A (Incorrect configuration): This is unlikely given the issues arose only after the upgrade.

  Why Not B (OS and device incompatibility): Upgrades check for compatibility before installation.

  Why Not D (Full storage): Storage issues typically prevent installation, not device functionality.

  Why Not F (Corrupted registry entries): While possible, this is less common than the selected answers.

• Question 392:

  A technician is installing the RAM for a graphs workstation. Which of the following is special purpose memory used by graphic controllers?

  A. SRAM
  B. MicroDlMM
  C. VRAM
  D. Unbuffered DIMM
  C. VRAM

  ---

  Explanation

  VRAM (Video Random Access Memory) is a special-purpose memory type used by graphics controllers to store image data that is displayed on the screen. VRAM is faster and more expensive than regular RAM, and it allows the graphics controller to access the image data directly without involving the CPU or the system memory. VRAM can improve the performance and quality of graphics-intensive applications, such as video editing, gaming, and 3D rendering.

• Question 393:

  A user accidentally spills liquid on a laptop. The user wants the device to be fixed and would like to know how much it will cost. Which of the following steps should the technician take NEXT to verify if the device is repairable before committing to a price? (Choose two.)

  A. Remove the case and organize the parts.
  B. Document the screw locations.
  C. Search the Internet for repair tutorials.
  D. Consult colleagues for advice.
  E. Place the device in rice for a few days.
  A. Remove the case and organize the parts.
  B. Document the screw locations.

• Question 394:

  Which of the following is the best way to protect the data of a virtual machine in the event of hardware failure?

  A. Redundant hardware
  B. UPS
  C. Cloud-based backup
  D. RAID
  C. Cloud-based backup

  ---

  Explanation

  Cloud-based backup is the best way to protect the data of a virtual machine, as it allows the data to be stored in a remote location that is accessible from anywhere. Cloud-based backup also provides scalability, security, and reliability for data protection3.

• Question 395:

  After an IT department implements SSL redirection, users report being unable to access a random number generator opened within a web browser.

  Which of the following should a technician do first to troubleshoot this issue?

  A. Ensure that the computer supports secure socket communication.
  B. Report the affected user accounts to the IT department.
  C. Reset the web browser cache.
  D. Check to see whether the website is HTTPS enabled.
  D. Check to see whether the website is HTTPS enabled.

  ---

  Explanation

  The first step to troubleshoot this issue is to check if the website that hosts the random number generator is HTTPS enabled. This means that the website supports secure communication using SSL certificates and encryption. If the website is not HTTPS enabled, it may not be compatible with the SSL redirection implemented by the IT department. SSL redirection is a technique that automatically redirects HTTP requests to HTTPS, ensuring that the data exchanged between the web browser and the website is protected. However, some websites may not have SSL certificates or may have expired or invalid ones, which can cause errors or warnings when trying to access them via HTTPS. Therefore, the technician should check the website's URL and see if it starts with https:// or http://. If it is the latter, the technician should try to manually change it to https:// and see if the website loads correctly. If it does not, the technician should contact the website owner or administrator and ask them to enable HTTPS or update their SSL certificates.

• Question 396:

  A virtual file server in the cloud is configured to automatically add compute resources during times of high load on the server. Which of the following describes this cloud feature?

  A. File synchronization
  B. High availability
  C. Rapid elasticity
  D. Shared resources
  C. Rapid elasticity

  ---

  Explanation

  Rapid elasticity is a cloud feature that allows cloud services to scale up or down automatically according to demand or load on the server, without requiring manual intervention or configuration changes by users or administrators.This enables

  cloud services to provide optimal performance and efficiency at all times, as well as reducing costs by only using resources when needed.

• Question 397:

  A software developer used client-side virtualization on a server to configure a web application. Although the application is working locally on the software developer's PC, other users on the LAN are not able to access the application.

  Which of the following would allow other users to access the application?

  A. Bridge networking
  B. Application virtualization
  C. Virtual desktop
  D. Site-to-site VPN
  A. Bridge networking

  ---

  Explanation

  Client-side virtualization is used to run an application or process on a separate virtual machine, isolated from the main operating system. To allow other users on the LAN to access the application, the software developer should configure a bridge networking connection between the virtual machine and the LAN. This will allow the virtual machine to communicate with other computers on the network. Application virtualization, virtual desktop, and site-to-site VPN are not necessary steps for allowing other users to access the application.

• Question 398:

  A user has decided to build a new computer with parts purchased from a popular online vendor The user has referenced online resources to assemble the unit. However, when the user presses the power button, the new computer does not load the operating system's installer. Instead, the onboard speaker beeps and immediately reports an issue on the screen. Which of the following is the MOST likely issue with the new build?

  A. The user did not plug in the processor's fan.
  B. The user did not apply thermal paste to the CPU.
  C. The user did not seat the GPU correctly.
  D. The user did not install the power supply.
  A. The user did not plug in the processor's fan.

  ---

  Explanation

  If a computer is not booting and the onboard speaker emits beeps, it can indicate a hardware issue. One of the most common causes of beep codes is overheating, which can occur if the processor's fan is not properly installed and running. The processor's fan is responsible for cooling the processor and preventing damage to the internal components.

• Question 399:

  Which of the following internet connection types would be the most readily available for users located on unimproved land that lacks infrastructure?

  A. Fiber
  B. Cable
  C. DSL
  D. Satellite
  D. Satellite

  ---

  Explanation

  Satellite internet is the most widely available internet connection type, as it does not depend on cables or wires. It can reach remote areas that lack infrastructure for other types of internet connections1.

• Question 400:

  Which of the following is used primarily for archiving data?

  A. PAN
  B. MAN
  C. SAN
  D. LAN
  E. WAN
  C. SAN

  ---

  Explanation

  A Storage Area Network (SAN) is primarily used for data archiving and large-scale storage. SANs provide high-speed, block-level storage for enterprise environments.

  Why Not A (PAN): Personal Area Networks are for connecting personal devices like phones and smartwatches.

  Why Not B (MAN): Metropolitan Area Networks are for city-wide data communication, not storage.

  Why Not D (LAN): Local Area Networks are for general connectivity, not dedicated storage.

  Why Not WAN: Wide Area Networks are for connecting geographically dispersed networks, not storage.
