• Question 1033:

  A server administrator is building a new application server. Which of the following, RAID levels provides MAXIMUM performance and redundancy?

  A. RAID 0
  B. RAID 1
  C. RAID 5
  D. RAID 10
  D. RAID 10

  ---

  Explanation

  RAID 10 is a combination of RAID 1 and RAID 0, which provides both performance and redundancy. RAID 1 mirrors data across two or more disks, while RAID 0 stripes data across two or more disks. RAID 10 combines these two methods to create a mirrored stripe set, which can tolerate multiple disk failures as long as they are not in the same mirror. RAID 10 requires at least four disks and offers better performance than RAID 5, which uses parity to provide redundancy.

• Question 1034:

  A technician is configuring a desktop RAID to allow for the best I/O performance and the most storage capacity possible. Which of the following RAID types should the technician use?

  B. 5
  C. 6
  D. 10
  A

  ---

  Explanation

  RAID 0 is a disk array configuration that splits data across two or more disks without parity or mirroring. RAID 0 provides the best I/O performance because it allows parallel read and write operations on multiple disks. RAID 0 also provides the most storage capacity possible because it does not use any disk space for redundancy. However, RAID 0 does not provide any fault tolerance and increases the risk of data loss if any disk fails.

• Question 1035:

  A customer called the help desk to request information about how to increase the volume on a laptop using only a keyboard. Which of the following keys would MOST likely allow this to be done?

  A. Alt
  B. Fn
  C. Tab
  D. Ctrl
  B. Fn

  ---

  Explanation

  To increase the volume on a laptop using only a keyboard, a user can press and hold down the Fn key while pressing one of the function keys (usually F1-F12) that has an icon representing volume up.

• Question 1036:

  A customer calls the help desk to report a problem connecting to a shared drive on a server. The technician determines that the user's server credentials have expired and reactivates them. Which of the following should the technician do next?

  A. Escalate the issue.
  B. Document the findings.
  C. Perform backups of all critical data.
  D. Verify system functionality.
  D. Verify system functionality.

• Question 1037:

  A user needs to upgrade the power supply of an older workstation to properly power a new graphics card. Which of the following criteria should the technician check to ensure the power supply will support the upgraded workstation? (Select two).

  A. Efficiency rating
  B. Heat dissipation
  C. Wattage
  D. Form factor
  E. Fan type
  F. Modular cabling
  C. Wattage
  D. Form factor

  ---

  Explanation

  The technician should check the wattage and the form factor of the power supply to ensure it will support the upgraded workstation. These are the two most important criteria for choosing a compatible and adequate power supply. Wattage: The wattage of a power supply is the maximum amount of power it can deliver to the components of the workstation. The wattage of the power supply should match or exceed the total power consumption of the components, especially the new graphics card, which is usually the most power-hungry part. If the power supply does not have enough wattage, it may cause instability, crashes, or damage to the workstation. To estimate the power consumption of the components, the technician can use a power supply calculator tool, such as the ones found in the web search results123. The technician should also add some headroom to the wattage, such as 20% to 50%, to account for peak power consumption, future upgrades, or power supply degradation. Form factor: The form factor of a power supply is the physical size and shape of the unit. The form factor of the power supply should fit in the case of the workstation and match the mounting holes and screws. The most common form factor for desktop power supplies is ATX, which measures 150 x 86 x 140 mm. However, some older or smaller workstations may use different form factors, such as SFX, TFX, or FlexATX. The technician should check the specifications of the workstation case and the power supply to ensure they have the same form factor. Other criteria, such as efficiency rating, heat dissipation, fan type, and modular cabling, are not essential for supporting the upgraded workstation, but they may affect the performance, noise, or aesthetics of the power supply. The efficiency rating is the percentage of input power that is converted to output power, and it indicates how much power is wasted as heat. The heat dissipation is the ability of the power supply to cool itself and prevent overheating. The fan type is the design and size of the fan that cools the power supply, and it affects the noise level and airflow of the unit. The modular cabling is the feature that allows the user to detach unused cables from the power supply, and it helps to reduce clutter and improve airflow inside the case.

• Question 1038:

  Which of the following network types would be used in a server room to connect virtual servers lo high-speed storage?

  A. WAN
  B. PAN
  C. MAN
  D. SAN
  D. SAN

  ---

  Explanation

  A Storage Area Network (SAN) is a dedicated, high-speed network that connects servers to data storage devices. SANs are used in server rooms to provide high- speed storage access to virtual servers.

• Question 1039:

  A technician replaces a laptop hard drive with an M.2 SSD. When the technician reboots the laptop, the laptop does not detect the SSD. Which of the following should the technician configure for the system?

  A. HSM
  B. Boot options
  C. UEFI settings
  D. TPM
  C. UEFI settings

  ---

  Explanation

  UEFI stands for Unified Extensible Firmware Interface, and it is a type of firmware that controls the boot process of a computer. UEFI settings allow the technician to configure various aspects of the boot process, such as the boot order, the boot mode, and the security options. If the technician replaces a laptop hard drive with an M.2 SSD, they may need to adjust the UEFI settings to enable the system to detect and boot from the new drive.

• Question 1040:

  A technician is troubleshooting a smartphone that has a large dark area on the screen. The screen has no damage to Indicate that It is cracked. Which of the following BEST describes why a blot Is on the screen?

  A. Digitizer damage
