• Question 783:

  A user is researching hard drives to upgrade a PC and has decided to purchase a NVMe drive. Which of the following Should the user confirm are available on the PC before making the purchase? (Select TWO).

  A. SATA
  B. M.2
  C. PCIe
  D. SAS
  E. SCSI
  F. DRAM
  B. M.2
  C. PCIe

  ---

  Explanation

  NVMe (Non-Volatile Memory Express) drives are high-speed solid-state drives that utilize the PCIe (Peripheral Component Interconnect Express) interface to connect to the motherboard. Before purchasing an NVMe drive, the user should confirm that the PC has an available M.2 slot for the drive and that the PC has a PCIe interface for the M.2 slot. SATA (Serial ATA) is an older interface for hard drives and is not compatible with NVMe drives. SAS (Serial Attached SCSI) is a newer interface for hard drives and is typically used for enterprise-level storage systems. SCSI (Small Computer System Interface) is a parallel interface for hard drives that is primarily used in high-end workstations and servers. DRAM (Dynamic Random Access Memory) is a type of memory commonly used in computers, but it is not relevant to the storage of data on a hard drive.

• Question 784:

  Which of the following technologies can allow multiple networks to traverse a switch?

  A. VLAN
  B. VRRP
  C. VPN
  D. DHCP
  A. VLAN

  ---

  Explanation

  The technology that allows multiple networks to traverse a switch is VLAN (Virtual Local Area Network) which is a logical grouping of devices on the same network regardless of their physical location12. Virtual Local Area Network (VLAN) technology can allow multiple networks to traverse a switch. A VLAN is a logical network created within a physical network that can separate traffic and allow multiple networks to coexist on the same physical network infrastructure. VRRP (Virtual Router Redundancy Protocol), VPN (Virtual Private Network), and DHCP (Dynamic Host Configuration Protocol) do not allow multiple networks to traverse a switch.

• Question 785:

  The GPS on a user's phone has been unreliable. Which of the following will MOST likely resolve the issue?

  A. Enabling high-accuracy mode
  B. Replacing the battery
  C. Disabling Wi-Fi connections
  D. Utilizing a third-party map application
  A. Enabling high-accuracy mode

  ---

  Explanation

  Enabling high-accuracy mode is the most likely action to resolve the issue of unreliable GPS on a user's phone. High-accuracy mode uses multiple sources of location data, such as Wi-Fi, cellular networks, and Bluetooth, to improve the accuracy and reliability of GPS. Replacing the battery, disabling Wi-Fi connections, or utilizing a third- party map application are unlikely to fix the GPS issue, as they are not directly related to the GPS function

• Question 786:

  Which of the following connects a PC to its default gateway?

  A. NIC
  B. Switch
  C. Router
  D. Cable modem
  B. Switch

  ---

  Explanation

• Question 787:

  A technician is relocating a router access point farther away from the modem to optimize signal coverage for a SOHO client. Which of the following will the technician most likely use to complete the relocation? (Select two).

  A. Punchdown tool
  B. Crimper
  C. Clamp-style wire stripper
  D. Network tap
  E. Wi-Fi analyzer
  F. Loopback plug
  B. Crimper
  E. Wi-Fi analyzer

  ---

  Explanation

  A crimper is a tool that is used to attach connectors to network cables, such as RJ-45 or RJ-11. A technician might need a crimper to create a longer cable for the router access point or to replace a damaged connector. A Wi-Fi analyzer is a software or hardware tool that can scan and measure the wireless signal strength, interference, channel usage, and security of a Wi-Fi network. A technician might need a Wi-Fi analyzer to find the optimal location and configuration for the router access point to improve the signal coverage for the SOHO client.

• Question 788:

  Which of the following types of devices MOST often uses a Thunderbolt cable?

  A. Linux PC
  B. Android mobile
  C. Apple laptop
  D. Chromebook
  C. Apple laptop

  ---

  Explanation

  Thunderbolt cables are commonly used to connect Apple laptops to external displays or other devices. While Thunderbolt is available on some Windows and Chromebook devices, it is most commonly associated with Apple products.

• Question 789:

  A technician is preparing to set up a gaming computer with the following components:

  1.Discrete, high-end graphics card

  2.Video capture card

  3.High-end processor

  4.Multiple hard drives

  5.USB 3.0 hub

  6.Sound card

  Which of the following options is the MOST important for the technician to consider before building the gaming computer?

  A. Redundant power supply
  B. Modular power supply
  C. 20-pin vs. 24-pin power adapter
  D. Power supply wattage rating
  D. Power supply wattage rating

  ---

  Explanation

  D. Power supply wattage rating is the MOST important for the technician to consider before building the gaming computer. This is because a high-end graphics card, video capture card, high-end processor, multiple hard drives, and USB 3.0 hub will require a large amount of power to function properly. The wattage rating of the power supply must match the requirements of these components to avoid power problems and instability in the computer. If the power supply is not powerful enough, it can cause component failure, system crashes, and other problems. Thus, it is crucial for the technician to choose a power supply with an adequate wattage rating that can support all the components of the gaming computer.

• Question 790:

  Which of the following services provides the ability to resolve UNC to appropriate IP addresses?

  A. DNS
  B. DHCP
  C. Proxy
  D. Web server
  A. DNS
