   Answer: A

   Explanation

   The best option that the technician should choose for the best performance is A. PCIe SSD connected via NVMe interface. This option means that the technician should install a solid state drive (SSD) that uses the PCIe (Peripheral Component Interconnect Express) bus and the NVMe (Non-Volatile Memory Express) protocol to communicate with the motherboard.

   A user's wireless laptop stopped working. A technician replaced the wireless card, but the wireless range is now limited. Which of the following should the technician perform NEXT?

   • AVerify the antenna's connection.
   • BSwitch from a 2.4GHz band to a 5GHz band.
   • CChange the channels of the Wi-Fi card settings.
   • DUpgrade the wireless driver.

   Show answer

   Answer: A

   Explanation

   A. Verify the antenna's connection. Here's why: Limited wireless range often points to a problem with signal strength. A loose or damaged antenna connection can significantly weaken the signal, resulting in a shorter range. Here's why the other options are less likely: B. Switch from a 2.4GHz band to a 5GHz band: While 5GHz generally offers faster speeds, it often has a shorter range than 2.4GHz. Switching to 5GHz might worsen the range issue. C. Change the channels of the Wi-Fi card settings: Changing channels can help improve signal strength if there's interference from other devices on the same channel. However, if the primary issue is a weak antenna connection, changing channels won't resolve the problem. D. Upgrade the wireless driver: An outdated driver could potentially cause various issues, including poor performance. However, it's less likely to be the primary cause of a sudden drop in wireless range after replacing the wireless card.

   A technician installed a Cat 5 UTP cable approximately 275ft (84m) from a network switch in an office to a workstation located on a factory floor. The technician sees both a flashing green LED and a flashing orange LED on the workstation's NIC. Which of the following should the technician do FIRST?

   • ACheck for loose connections, pinched bends, and physical damage.
   • BInstall a powered hub as close as possible to the halfway point in the Cat 5 UTP cable run.
   • CReplace the entire run of Cat 5 UTP cable with Cat 5 STP cable.
   • DUpgrade the entire cable run to multimode fiber.

   Show answer

   Answer: A

   Explanation

   I’m willing to bet they are referring to what could be the beginnings of port flapping. They use “flashing” here instead of blinking. Both green and orange “blinking” lights are indicative of data being transferred, completely normal. “Flashing” I’m suspecting in a cyclical manner (port flapping) would be something you’d want to look at your physical cable.

   A user reports that a display is slow to turn on, and the colors are distorted and discolored. Once the display turns on, it appears to have lines going through the image and intermittently goes blank. Which of the following is the most likely cause of the issue?

   • AIncorrect data source
   • BIncorrect resolution settings
   • CPhysical cabling issues
   • DIncorrect refresh rate
   • EDisplay burn-in

   Show answer

   Answer: C

   Explanation

   Physical cabling issues can lead to problems like distorted colors, lines on the screen, intermittent blanking, and slow display turn-on. Loose or damaged cables, connectors, or pins can result in data transmission problems between the computer and the monitor.

8. Question 268 · 624 in bank

   A technician replaced a motherboard on a server, and now the 64-bit hypervisor is not loading correctly. Which of the following needs to be enabled for the hypervisor to run?

   • AHardware prefetcher
   • BHyperthreading
   • CvPro
   • DVT-d

   Show answer

   Answer: D

   Explanation

   D. VT-d (Virtualization Technology for Directed I/O) needs to be enabled for the hypervisor to run. VT-d is a hardware-level technology that enables the direct assignment of physical devices to virtual machines. This allows for improved security and isolation of the virtual environment, which is crucial for running a hypervisor. If VT-d is not enabled, the hypervisor may not be able to access the physical hardware resources it needs, causing issues with loading and running correctly.

9. Question 269 · 624 in bank

   Which of the following wireless technologies would a company most likely implement for inventory management?

   • ANFC
   • B5G
   • CBluetooth
   • DRFID

   Show answer

   Answer: D

   Explanation

   D. RFID (Radio Frequency Identification). RFID technology allows for automatic identification and tracking of inventory items using radio frequency signals. It's commonly used in inventory management systems because it enables efficient and accurate tracking of goods throughout the supply chain, from production to distribution to retail. RFID tags can be attached to individual items or pallets, and RFID readers can quickly scan and update inventory data without requiring line-of-sight contact.

10. Question 270 · 624 in bank

    A systems administrator hears a clicking noise coming from a storage array that has a RAID configuration. No LEDs are illuminated on the array, but the logs show several hard drive errors. Which of the following should the systems administrator do to quickly eliminate the clicking?

    • AReinstall the drive
    • BReplace the bad drive.
    • CReset the RAID software.
    • DRun a chkdsk on the drive.

    Show answer

    Answer: B

    Explanation

    B. Replace the bad drive. Replacing the failing drive with a new one is the most appropriate course of action to maintain the integrity of the RAID array and prevent further damage or loss of data. Reinstalling the drive or resetting the RAID software may not resolve the underlying hardware issue causing the clicking noise and errors. Running a chkdsk on the drive might be helpful for diagnosing and repairing filesystem issues, but it's not likely to resolve a mechanical failure causing clicking noises.
