• Question 71:

  A classroom projector, which is turned on, displays a flashing LED code but does not have any video output. Which of the following should a technician do to resolve the issue?

  A. Replace the bulb.
  B. Adjust the input resolution_

  Explanation

  If the lamp light is flashing orange or red, this usually means the lamp light is going to burn out soon or needs to be replaced

• Question 72:

  Which of the following provides the highest level of isolation from the host operating system?

  A. Type Il hypervisor
  B. Resource pooling
  C. Hardware-assisted virtualization
  D. Single-node clustering
  C. Hardware-assisted virtualization

  ---

  Explanation

  Hardware-assisted virtualization, often implemented through technologies like Intel VT-x or AMD-V, allows the hypervisor to directly manage hardware resources, enhancing the isolation between virtual machines (VMs) and the host operating system. With hardware-assisted virtualization, VMs have more direct access to physical hardware resources, reducing the potential for interference or compromise from the host operating system.

• Question 73:

  A user's Windows PC is unable to connect to the network at a new branch office that the user is visiting. A technician discovers the PC is unable to ping the local gateway. Which of the following commands should the technician use next?

  A. ipconfig
  B. cd config
  C. ifconfig
  D. show config
  A. ipconfig

  ---

  Explanation

  ipconfig is a command-line tool that displays the current configuration of the network interfaces on a Windows PC. It can also be used to release and renew the IP address, flush the DNS cache, and display the routing table. If the PC is unable to ping the local gateway, the technician should use ipconfig to check the IP address, subnet mask, default gateway, and DNS servers of the PC. The technician can also use ipconfig /renew to request a new IP address from the DHCP server, or ipconfig /flushdns to clear the DNS cache.

• Question 74:

  A technician needs to increase the available RAM on a virtual workstation. Which of the following should the technician do?

  A. Increase the ECC memory timings in the BIOS.
  B. Upgrade to the latest DDR5 modules.
  C. Clear the temporary files on the workstation's boot drive.
  D. Use a hypervisor to adjust the resource allocation.
  D. Use a hypervisor to adjust the resource allocation.

  ---

  Explanation

  A hypervisor is a software layer that manages and allocates resources for virtual machines (VMs) on a physical host machine. A technician can use a hypervisor to adjust the resource allocation for a virtual workstation, such as increasing the

  amount of RAM assigned to it from the available pool of memory on the host machine. This can improve the performance and functionality of the virtual workstation without requiring any hardware changes or modifications.

• Question 75:

  Several computers are having network connectivity issues. Two of the computers are wired and are not having any issues. The technician verifies that none of the computers having issues have been assigned a static IP.

  Which of the following should the technician check NEXT?

  A. Check the closest AP for the area.
  B. Check each wireless adapter switch
  C. Check the group's network switch.
  D. Check the DHCP server.
  A. Check the closest AP for the area.

• Question 76:

  In which of the following cloud models is the customer not responsible for hardware and OS layers but is responsible for the data and the application?

  A. PaaS
  B. SaaS
  C. laaS
  D. CaaS
  A. PaaS

  ---

  Explanation

  In Platform as a Service (PaaS), the cloud provider manages the hardware, operating system, and middleware, while the customer is responsible for managing data and applications.

  Why Not B (SaaS): In SaaS, the provider manages all layers, including applications and data, leaving no responsibility for the customer.

  Why Not C (IaaS): In IaaS, the customer manages the OS, data, and applications, while the provider only handles the hardware.

  Why Not D (CaaS): CaaS (Container as a Service) is not a primary cloud model described in the CompTIA objectives and is less commonly referenced.

• Question 77:

  A technician is replacing the power supply in a computer.

  Which of the following safety measures should the technician take to protect the computer?

  A. Wear an antistatic wrist strap.
  B. Wear protective eyewear.
  C. Wear gloves.
  D. Minimize the use of tools.
  A. Wear an antistatic wrist strap.

  ---

  Explanation

  When replacing a power supply in a computer, wearing an antistatic wrist strap is crucial to prevent static electricity from damaging the computer components. Static electricity can easily damage sensitive electronic components within the computer; therefore, using an antistatic wrist strap helps to ground the technician, mitigating the risk of electrostatic discharge. The other options provide general safety but do not address the primary concern of electrostatic discharge in this context.

• Question 78:

  A technician is upgrading a user's laptop from an HDD to an SSD. The user's laptop only has a single bay for a hard drive. Which of the following characteristics of the SSD is the most important in this scenario?

  A. Partition type
  B. Storage size
  C. Form factor
  D. Transfer speed
  C. Form factor

  Which of the following settings should the technician advise the user to change in the printer settings?

  A. Collate
  B. Orientation
  C. Duplex
  D. Transparency
