  A. Fiber
  B. DSL
  C. Satellite
  D. Coaxial

• Question 724:

  A laser printer is making humming and grinding noises, and the printouts have ghost images on the pages. Which of the following should be replaced?

  A. Cartridge
  B. Paper
  C. Fuser
  D. Rollers
  C. Fuser

  ---

  Explanation

  The most likely answer is

  C. Fuser.

  A fuser is a component in a laser printer that uses heat and pressure to fuse the toner powder onto the paper. If the fuser is damaged or worn out, it can cause humming and grinding noises, as well as ghost images on the printouts. Ghost

  images are faint copies of previous images that appear on the same page. They are caused by the fuser not heating the toner properly, or by the toner sticking to the fuser roller and transferring to the next page12. To fix this problem, you

  should replace the fuser unit with a new one. You can check your printer manual for instructions on how to remove and install the fuser unit. You can also use a diagnostic ruler to measure the distance between the ghost images and

  determine if the fuser is the source of the problem2. If the ghost images are far apart (between 4cm and 5cm), then the fuser is likely to be faulty.

• Question 725:

  A technician has set up a new conference room with a TV and a video soundbar. The technician wants to test the system with a conference call. During the test, the TV speaker produces sound, but the soundbar does not. Which of the following is the MOST likely cause of the issue?

  A. The volume on the TV needs to be turned up
  B. The conference call needs to be unmuted for audio.
  C. An incorrect HDMI cable is being used.
  D. The TV's HDMI-ARC port is not being used.
  D. The TV's HDMI-ARC port is not being used.

  ---

  Explanation

  HDMI-ARC (Audio Return Channel) is an HDMI connection that allows audio to be sent from the TV to an external sound system, such as a soundbar. If the TV's HDMI-ARC port is not being used, then the soundbar will not receive any audio from the TV and thus will not produce any sound. To resolve the issue, the technician should ensure that the TV's HDMI-ARC port is being used to connect the TV to the soundbar.

• Question 726:

  When a user's workstation is turned on, a message displays indicating that the date and time are incorrect. Other computers on the network do not display this message. Which of the following is the most likely cause of this issue?

  A. The time server is misconfigured.
  B. The BIOS is not updated.
  C. The CMOS battery is discharged.
  D. The CPU is slow.
  C. The CMOS battery is discharged.

  ---

  Explanation

  The CMOS (complementary metal-oxide-semiconductor) is a small chip on the motherboard that stores the BIOS settings, including the date and time. The CMOS battery is a coin cell battery that provides power to the CMOS chip when the computer is turned off, so that the BIOS settings are not lost. If the CMOS battery is discharged, the CMOS chip will lose its data, and the date and time will be reset to the default values. This will cause a message to display indicating that the date and time are incorrect when the computer is turned on. The other computers on the network do not display this message because they have functional CMOS batteries. The most likely cause of this issue is the CMOS battery is discharged, and it needs to be replaced with a new one12.

• Question 727:

  A user wants to overclock a GPU but is concerned about potential overheating. Which of the following would best address the user's concern?

  A. Thicker thermal pads
  B. Liquid cooling
  C. Larger heat sink
  D. Fan upgrade
  B. Liquid cooling

  ---

  Explanation

  Liquid cooling systems are highly effective at dissipating heat generated by overclocked components, such as GPUs. They use a liquid coolant to absorb heat from the GPU and transfer it away from the component, providing superior cooling performance compared to air cooling solutions like larger heat sinks or fan upgrades. Thicker thermal pads can also help with heat dissipation, but they may not be as effective as liquid cooling for significant overclocking.

• Question 728:

  DRAG DROP

  A natural disaster occurred, and the storage system for the development team is unrecoverable. The technician is preparing replacement storage arrays that include a hypervisor with the capacity to support several virtual machines. Two separate bays are available, and both should be utilized.

  Requirements for the primary array include the following:

  1. No need to be scalable

  2. Very fast on reads

  3. Fault tolerance of one drive

  4. Ability to function with only one drive

  5. Easily recoverable data

  6. High redundancy

  7. Minimum number of drives

  Requirements for the secondary array include the following:

  1. Fault tolerance of one drive

  2. Total space of 600G3

  3. Best write performance

  4. Minimum number of drives

  Instructions:

  Drag and Drop the appropriate Hard Drives. Then Open each array to complete the configuration.

• Question 729:

  Which of the following network devices operates as a bridge function?

  A. Hub
  B. Wireless access point
  C. Transceiver
  D. Media converter
  D. Media converter

  ---

  Explanation

  A media converter is a network device that operates as a bridge function, which means it connects two different types of network media, such as copper and fiber optic cables, and converts signals between them. This allows network devices

  that use different media types to communicate with each other over long distances or in different environments, without requiring major changes or upgrades to the existing network infrastructure.

• Question 730:

  A technician is troubleshooting a PoE phone that will not turn on. When a laptop is plugged directly into the switchport for the phone the technician sees a data link LED and activity.

  Which of the following tools should the technician use to verify PoE availability to the phone?

  A. Network tap
  B. Cable tester
  C. Loopback plug
  D. Toner probe
  B. Cable tester

  ---

  Explanation

  Reasoning: A cable tester capable of testing Power over Ethernet (PoE) functionality can verify whether the switchport is providing the required power to the phone. This tool measures both the presence of data and the voltage or wattage being provided through the Ethernet cable. This is the most effective way to confirm that PoE is available on the port.

  Practical Example:

  A PoE phone might not turn on due to a misconfigured or faulty switchport. Using a cable tester capable of measuring PoE would help the technician determine if the switchport is supplying sufficient power to the phone.
