• Question 451:

  A user creates a support ticket to report a conference room projector that does not work. The user says that even though the provided cables are being used, the projector screen shows the following error message:

  No signal input

  Which of the following describes the FIRST action that should be taken?

  A. Verify that the projector is turned on.
  B. Verify that the user is using an approved OS.
  C. Replace the projector bulb.
  D. Check the video cable and replace it if necessary.
  D. Check the video cable and replace it if necessary.

  ---

  Explanation

  The most common reasons you may be seeing the "No Signal" message:

  The projector and the source device are not connected correctly. The first action should be to check the video cable and replace it if necessary, as the error message suggests that the projector is not receiving a signal from the laptop.

  Verifying that the projector is turned on and checking the bulb would come after verifying the video cable.

• Question 453:

  Which of the following 802.11 standards supports both 5GHz and 2.4GHz channel frequencies?

  A. 802.11a
  B. 802.11c
  C. 802.11b
  D. 802.11g
  B. 802.11c

  ---

  Explanation

  802.11ac is the 802.11 standard that supports both 5GHz and 2.4GHz channel frequencies. 802.11ac is the latest wireless networking standard that operates in both the 5GHz and 2.4GHz frequency bands. It provides higher wireless network speeds and better reliability compared to previous standards, such as 802.11a, 802.11b, and 802.11g. The 802.11a standard operates exclusively in the 5GHz band, while the 802.11b and 802.11g standards operate exclusively in the 2.4GHz band.

• Question 454:

  Which of the following should the label on a network jack faceplate refer to?

  A. MAC address
  B. Patch panel port
  C. Switch port in use
  D. VLAN identification
  B. Patch panel port

  ---

  Explanation

  A network jack faceplate is a device that covers and protects the network jack or outlet on a wall or a floor. A network jack or outlet is a physical interface that allows a network cable, such as an Ethernet cable, to be plugged into a network device, such as a computer or a printer. A network jack faceplate usually has one or more ports that correspond to different types of network cables, such as RJ-45, RJ-11, or coaxial. A label on a network jack faceplate should refer to the patch panel port that the network jack or outlet is connected to. A patch panel is a device that connects multiple network cables in an organized and convenient way. A patch panel has a number of ports that correspond to different cables, such as Ethernet, coaxial, or fiber-optic cables. A patch panel can help simplify the wiring and management of a network, as well as provide flexibility and scalability for adding or changing network devices. By labeling the network jack faceplate with the patch panel port, the network technician can easily identify and trace the cable that is connected to the network jack or outlet. This can help to troubleshoot and resolve network issues, such as connectivity, performance, or configuration problems. It can also help to avoid confusion or errors when installing or modifying network cables.

• Question 455:

  A technician is designing a new laptop for a local construction company. Company employees will move the laptop around frequently and are likely to drop the laptop while working. Which of the following drives should the technician install to mitigate for potential damage?

  A. S.M.A.R.T
  B. SCSI
  C. RAID
  D. Solid-state
  D. Solid-state

  ---

  Explanation

  Solid-state drives (SSDs) are the best choice for laptops that are likely to drop while working, as they have no moving parts and are more resistant to shock and vibration than hard-disk drives (HDDs). SSDs also offer faster performance, lower power consumption, and less noise and heat than HDDs. SSDs use flash memory chips to store data, unlike HDDs that use spinning platters and read/write heads. SSDs can be connected to laptops using various interfaces, such as SATA, PCIe, or NVMe. The other options are not suitable for this scenario. S.M.A.R.T (Self-Monitoring, Analysis, and Reporting Technology) is a feature that monitors the health and performance of HDDs and SSDs, but it does not prevent damage from dropping. SCSI (Small Computer System Interface) is an interface that connects various devices, such as HDDs, SSDs, scanners, and printers, to a computer, but it is not commonly used in laptops. RAID (Redundant Array of Independent Disks) is a system that combines multiple HDDs or SSDs into a single logical unit, providing redundancy, performance, or both, but it is not feasible or practical to implement RAID in a laptop.

• Question 456:

  An administrator is replacing 15,000rpm hard drives in a server. Which of the following is the interface type the drives most likely use?

  A. IDE
  B. SAS
  C. eSATA
  D. SATA
  B. SAS

  ---

  Explanation

  SAS stands for Serial Attached SCSI, which is a bit serial interface successor to SCSI sponsored by ANSI and introduced in 20041. SAS is the most common interface for enterprise HDDs, especially those with high performance and high reliability requirements, such as 15,000rpm drives23. SAS offers faster data transfer speeds, lower power consumption, and better scalability than other interfaces1.

• Question 457:

  A user is printing a part with a thermoplastic polyurethane (TPU) filament on a 3-D printer. The first layer on every print job is not adhering properly.

  Which of the following should the user do to improve adherence on the first layer?

  A. Lower the print bed temperature.
  B. Adjust the RPM of the cooling fan.
  C. Increase the print speed.
  D. Raise the filament flow amount.
  D. Raise the filament flow amount.

• Question 458:

  An engineer is troubleshooting a missing new drive in Windows 10 and discovers the drive was formatted before going offline.

  Which of the following steps should the engineer take to resolve the issue?

  A. Close any applications that are utilizing too many resources.
  B. Remove any excess cables connected to the motherboard.
  C. Check if the drive was formatted to ext4.
  D. Enable low power mode on all the other connected devices.
  C. Check if the drive was formatted to ext4.

  ---

  Explanation

  When a new drive is not recognized by Windows 10, and it's known that the drive was formatted before going offline, checking the file system format is crucial. Windows does not natively recognize the ext4 file system, commonly used in Linux environments. If the drive was inadvertently formatted to ext4, Windows would not display or allow access to it. The solution involves reformatting the drive to a file system that Windows recognizes, such as NTFS or FAT32, ensuring the drive becomes visible and accessible within Windows 10.

• Question 459:

  A bank wants to leverage cloud computing but would like a cloud solution in which infrastructure is shared with businesses in the same industry. Which of the following cloud models would BEST address the bank's need?

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

  ---

  Explanation

  A community cloud model is a cloud solution in which infrastructure is shared among organizations that have common interests, goals, or concerns, such as security, compliance, or industry standards. This model would best address the bank's need to leverage cloud computing while maintaining a high level of security and privacy for its data and transactions. The other cloud models are not suitable for this scenario, as they either do not offer enough control over the infrastructure (public cloud), or do not allow for sharing of resources among similar organizations (private cloud and hybrid cloud).
