• Question 632:

  A user wants RAID to be configured on a desktop to allow the fastest speed and maximum storage capacity. Which of the following RAID types should a technician configure to accommodate this request?

  B. 1
  C. 5
  D. 10
  A

  ---

  Explanation

  RAID 0 is a configuration that stripes data across multiple disks without parity or redundancy. It provides the fastest speed and maximum storage capacity among the RAID types listed, but it also has no fault tolerance. RAID 1 mirrors data across two disks, providing redundancy but halving the storage capacity. RAID 5 stripes data across three or more disks with parity, providing fault tolerance but reducing the storage capacity by one disk. RAID 10 combines mirroring and striping across four or more disks, providing both speed and redundancy but reducing the storage capacity by half.

• Question 633:

  Multiple organizations are working together on a project and want to migrate the data to the cloud.

  Which of the following cloud models should be used?

  A. Public
  B. Hybrid
  C. Private
  D. Community
  D. Community

  ---

  Explanation

  A community cloud is designed for multiple organizations with shared goals or projects, allowing collaboration while maintaining a level of privacy. This cloud model is ideal for the scenario where organizations are working together and need to migrate project-related data to the cloud.

  Why Not A (Public): Public cloud is shared among all users and lacks the collaboration-specific features of a community cloud.

  Why Not B (Hybrid): Hybrid cloud combines public and private resources but is not tailored to multiple organizations working on a joint project.

  Why Not C (Private): Private cloud is exclusive to a single organization and unsuitable for collaboration among multiple entities.

• Question 634:

  A network administrator would like to increase network bandwidth to iGbps between two office buildings that are 0.5mi (805m) apart. Which of the following would be the BEST solution?

  A. Fiber
  B. Coaxial
  C. Plenum
  D. Cat 6
  A. Fiber

• Question 635:

  A laptop's external webcam software is running, but it shows no image or video. Which of the following should a technician perform FIRST?

  A. Research new webcam firmware.
  B. Restart the computer and run system diagnostics.
  C. Reseat the webcam.
  D. Reinstall the webcam software and drivers.
  C. Reseat the webcam.

  Explanation

  https://www.lifewire.com/fix-it-when-webcam-is-not-working-4588517 If a laptop's external webcam software is running, but it shows no image or video, the first step the technician should perform is to reseat the webcam. Reseating the

  webcam involves disconnecting it from the motherboard and then reconnecting it. If this doesn't work, the technician should then check the webcam drivers or software.

• Question 636:

  Which of the following environments can be set up to keep any device from communicating with a virtual machine over the network?

  A. Development
  B. Test
  C. Sandbox
  D. Cross-platform
  C. Sandbox

  ---

  Explanation

  A sandbox environment is designed to isolate and contain software or programs, preventing them from interacting with other parts of the system or network. This isolation can be used to safely run untested or untrusted programs or code without risking the integrity of the host system or network. Setting up a virtual machine within a sandbox environment ensures that the VM has no communication with other devices over the network, providing a controlled and secure environment for testing or development purposes.

  References:

  CompTIA A+ Core 1 (220-1101) Exam Objectives, particularly the sections on virtualization and cloud computing, which may cover the concept of sandboxing as a form of virtualization used for security and testing. Understanding of virtualization technologies and security practices, including the use of sandbox environments to contain and limit the potential impact of untrusted or experimental software.

• Question 637:

  Which of the following best characterizes the use of a virtual machine as a sandbox?

  A. Run an application on multiple workstations without installation.
  B. Explore how an application behaves in a different environment
  C. Migrate a currently used legacy application from physical to virtual
  D. Create a firewall where the sandbox acts as a perimeter network.
  B. Explore how an application behaves in a different environment

  ---

  Explanation

  A sandbox in virtualization allows testing an application in an isolated environment to observe its behavior without affecting the host system.

  Why Not A (Run an application on multiple workstations): This describes application virtualization, not sandboxing.

  Why Not C (Migrate a legacy application): This is about virtualization for legacy support, not testing.

  Why Not D (Create a firewall): A firewall does not act as a sandbox for application testing.

• Question 638:

  A laptop is displaying vertical lines in different colors on the screen.

  Which of the following components should a technician replace to most likely correct this issue?

  A. Inverter
  B. Motherboard
  C. Low-voltage differential signaling cable
  D. Liquid crystal display
  D. Liquid crystal display

  ---

  Explanation

  Vertical lines in different colors on a laptop screen are often indicative of an issue with the liquid crystal display (LCD) itself. This could be due to a damaged display panel or issues with the connections between the display and the rest of the system. Replacing the LCD is the most likely solution to resolve this issue, as it addresses potential faults in the display hardware that are causing the visual artifacts.

• Question 639:

  An office has a network that has all computers connected to two switches. The switches are connected with a fiber cable. The computers and switches are all located in the same building. Which of the following network types does this describe?

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

  A. Connect to a hotspot
  B. Request a traffic exemption.
  C. Change the DNS address to 1.1.1.1
  D. Update the Group Policy settings
  B. Request a traffic exemption.

  ---

  Explanation

  If a technician is on site troubleshooting a customer's laptop and needs to download a software update but the company's proxy is blocking updates, the most appropriate action for the technician to take would be to request a traffic exemption from the company's IT department.
