   A user reports intermittent connectivity. The technician checks the network logs and sees the following output:

   

   Which of the following is the most likely reason for this issue?

   • AExternal interference
   • BHigh latency
   • CJitter
   • DPort flapping

   Show answer

   Answer: D

   Explanation

   Troubleshoot Port Flapping Issues Intermittent connectivity might manifest as port flapping , which means that the NIC or switch interface transitions continually between up and down states. This is often caused by bad cabling or external interference or a faulty NIC at the host end. You can use the switch configuration interface to report how long a port remains in the up state.

   A technician recently installed a new printer that is being shared over the network via a 64-bit Windows Print Server. Two users, who have computers with a legacy OS, are unable to print to this new printer. Which of the following should the technician do to resolve this issue?

   • AEnable 32-bit drivers on the Print Server.
   • BEnable Print Spooler and restart the computer.
   • CRun Windows Update on the users' computers.
   • DUpdate the computers to a 64-bit driver.

   Show answer

   Answer: A

   Explanation

   To resolve the issue where users with legacy OS are unable to print to a new printer shared over the network via a 64-bit Windows Print Server, the technician should: A. Enable 32-bit drivers on the Print Server. Explanation: Legacy operating systems, especially 32-bit versions, may not be compatible with 64-bit printer drivers. Enabling 32-bit drivers on the Print Server allows these users to download and install the appropriate drivers for their legacy systems.

   Which of the following solutions can help users who have the current Windows operating systems run legacy applications that are not supported under the latest applications?

   • AAppLocker
   • BType 1 hypervisors
   • CSandbox
   • DApplication virtualization

   Show answer

   Answer: D

   Explanation

   The best answer here is D. Application virtualization Here's why: Application Virtualization: This technology creates a virtual environment or container in which legacy applications can run isolated from the main operating system. This allows them to function on newer versions of Windows even when they have incompatibilities.

7. Question 277 · 624 in bank

   A technician is replacing a failed drive in a RAID 5 array. Which of the following is the first step the technician should take before hot swapping the drive out of the array?

   • ADocument the replacement date.
   • BShut down the array.
   • CSafely dispose of the failed drive.
   • DPerform a full backup.

   Show answer

   Answer: D

   Explanation

   The correct answer is B. Shut down the array. Before replacing a drive in a RAID 5 array, the technician should first shut down the array to ensure the following: · The array is not actively writing data to the failed drive. · The array is not in a state of rebalancing or rebuilding. · The technician can safely remove the failed drive without causing further data corruption or loss. Here's why the other options are not the first step: A. Documenting the replacement date (A) is important for maintenance records, but it's not the first step. C. Safely disposing of the failed drive (C) is important for data security and environmental reasons, but it's not the first step. D. Performing a full backup (D) is a good practice, but it's not necessary before replacing a drive in a RAID 5 array, as the array is designed to tolerate a single drive failure. Shutting down the array ensures the technician can safely replace the failed drive without risking further data loss or corruption.

   An administrator notices that on an intermittent basis the virtual machines are running slowly. The virtual machines are correctly sized, and the hardware has enough free resources to cope with demand. Which of the following is most likely the cause?

   • AThe physical servers are not able to draw enough power.
   • BThe physical servers do not have enough network bandwidth.
   • CThe physical servers are throttling due to overheating.
   • DThe physical servers are contending for resources.

   Show answer

   Answer: C

   Explanation

   I agree with both of you Farticus and Flarga. The statement in the question rule out D to be the right option from my view as the hardware has enough free resources to cope with demand, hence I go with C.

9. Question 279 · 624 in bank

   A user's mobile phone gets really hot to the touch and does not retain a charge. The user also reports that the phone is very slow, especially while charging. Which of the following is MOST likely causing these symptoms?

   • ABroken charging port
   • BDigitizer failure
   • CCPU overheating
   • DDefective battery

   Show answer

   Answer: D

   Explanation

   A defective battery is the most likely cause of the symptoms described for a user's mobile phone getting really hot to the touch, not retaining a charge, and being very slow, especially while charging. A defective battery may not hold a charge properly, leading to the phone running out of power quickly and the need for frequent charging. The defective battery may also cause the phone to overheat, especially while charging, as the battery attempts to charge but fails to hold a charge, resulting in the battery continuing to draw power and generating heat. A broken charging port or digitizer failure would not cause the phone to get hot or affect the battery's ability to hold a charge. CPU overheating may cause the phone to get hot but is less likely to affect the battery's ability to hold a charge.

10. Question 280 · 624 in bank

    Which of the following technologies can be used to harden guest virtual machines?

    • AContainerization
    • BNetwork isolation
    • CResource reservation
    • DvTPM

    Show answer

    Answer: D

    Explanation

    The most appropriate technology to harden guest virtual machines is: D. vTPM (Virtual Trusted Platform Module). vTPM provides hardware-based security functions to virtual machines, similar to how a physical TPM works for physical machines. It helps in securing cryptographic operations, storing encryption keys, and ensuring the integrity of the system. Why the other options are less suitable for hardening: A. Containerization: While containerization can improve security by isolating applications, it is more relevant to application deployment rather than hardening virtual machines. B. Network isolation: This can enhance security by limiting network access, but it doesn’t directly harden the virtual machine itself. C. Resource reservation: This ensures that virtual machines have guaranteed access to resources, but it doesn’t contribute to the security or hardening of the virtual machines.
