• Question 602:

  During an OS migration, a technician is unable to find compatible current software for a specialized hardware device. Which of the following actions should the technician take to complete the migration?

  A. Restrict user access.
  B. Virtualize the application.
  C. Replace the PC.
  D. Upgrade the BIOS to UEFI.
  B. Virtualize the application.

  ---

  Explanation

  Virtualizing the application is the best action that a technician can take to complete the OS migration when there is no compatible current software for a specialized hardware device. Virtualizing the application means running the application in a virtual machine (VM) that emulates the previous OS environment that supports the application and the hardware device. This way, the technician can avoid the need to replace the PC or the hardware device, or to restrict user access to the application. Virtualizing the application also allows the technician to benefit from the new OS features and security updates, while maintaining the functionality and compatibility of the application and the hardware device. The other options are not as effective or feasible for this scenario. Restricting user access may prevent unauthorized or accidental changes to the application or the hardware device, but it does not solve the compatibility issue or allow the OS migration to proceed. Replacing the PC or the hardware device may be costly, time-consuming, or impractical, especially if the hardware device is rare, expensive, or customized. Upgrading the BIOS to UEFI may improve the boot speed, security, and compatibility of the PC, but it does not guarantee that the application or the hardware device will work with the new OS.

• Question 604:

  A technician is diagnosing a workstation that shuts down unexpectedly during a butn-in test. Which of the following is the MOST likely cause for this symptom?

  A. Faulty CMOS battery
  B. OS update issue
  C. Overheating
  D. Faulty RAM
  C. Overheating

  ---

  Explanation

  If a workstation shuts down unexpectedly during a burn-in test, overheating is the most likely cause. This is because a burn-in test is designed to stress the components of the workstation, which can generate a lot of heat. Therefore, overheating is the correct answer.

• Question 605:

  A laptop does not have any audio output from the built-in speakers. The Windows Device Manager shows a down arrow for the audio device. Which of the following will correct this audio issue?

  A. Replacing the speakers
  B. Increasing the volume
  C. Enabling the audio device
  D. Updating the driver
  C. Enabling the audio device

  ---

  Explanation

  Enabling the audio device is the correct action to correct an audio issue where a laptop does not have any audio output from the built-in speakers and Windows Device Manager shows a down arrow for the audio device. A down arrow indicates that the audio device is disabled and needs to be enabled by right-clicking on it and selecting Enable device. Replacing the speakers, increasing the volume, or updating the driver are unlikely to solve the issue if the audio device is disabled.

• Question 606:

  An administrator is setting up a conference room for an important board of directors meeting. The chief operating officer has asked the administrator to make sure a redundant internet connection is available. The office only has one ISP. and the conference room equipment is currently configured using Ethernet.

  Which of the following should the administrator set up in order to ensure redundancy?

  A. Wireless access point
  B. Near-field communication
  C. Hotspot
  D. Bluetooth
  C. Hotspot

  ---

  Explanation

  A hotspot provides a redundant internet connection using cellular data. This ensures connectivity for the meeting even if the primary ISP connection fails.

  Why Not A (Wireless access point): A wireless access point expands Wi-Fi connectivity but does not provide internet redundancy.

  Why Not B (Near-field communication): NFC is used for short-range communication, not internet connectivity.

  Why Not D (Bluetooth): Bluetooth is for short-range device pairing and cannot serve as a backup internet connection.

• Question 607:

  A network administrator must install a device that will proactively stop outside attacks from reaching the LAN.

  Which of the following devices would BEST meet the organization's needs?

  A. IPS
  B. IDS.
  C. Proxy server

• Question 608:

  A user needs to transfer files from an Apple phone to a workstation. Which of the following connection types should the user utilize?

  A. USB-C
  B. Serial
  C. Lightning
  D. NFC
  C. Lightning

  ---

  Explanation

  Lightning is a proprietary connection type that is used by Apple devices, such as iPhones, iPads, and iPods, to transfer data, charge, and connect to accessories. Lightning cables have a reversible 8-pin connector that can be plugged into a USB port on a workstation or a power adapter. USB-C, serial, and NFC are not compatible with Apple phones.

• Question 610:

  A technician is running a 279ft (85m) network cable between buildings that will share conduit with a large power cable. Which of the following is the most appropriate cable for the technician to use for this project?

  A. Fiber
  B. Coaxial
  C. Cat 5e
  D. Cat 6
  A. Fiber

  ---

  Explanation

  Fiber optic cables are less susceptible to electromagnetic interference (EMI) and radio-frequency interference (RFI) compared to copper cables like Cat 5e, Cat 6, or coaxial cables.

  When running cables in close proximity to a large power cable, there is a higher risk of electromagnetic interference. Fiber optic cables are immune to such interference, making them a suitable choice for ensuring reliable and high-performance data transmission.
