• Question 831:

  A user reports that all print jobs sent to a laser printer have random and incorrect characters throughout the pages. Which of the following actions should the technician do to resolve this issue?

  A. Replace the fuser.
  B. Adjust the rollers.
  C. Update the driver.
  D. Shake the toner
  C. Update the driver.

  ---

  Explanation

  One of the possible causes of random and incorrect characters appearing on print jobs sent to a laser printer is an outdated or corrupted driver. The driver is a software component that communicates between the operating system and the

  printer, and converts data into a format that the printer can understand. If the driver is outdated or corrupted, it may send incorrect or garbled data to the printer, resulting in poor print quality or errors. The technician should update the driver to

  the latest version from the manufacturer's website, or uninstall and reinstall it if necessary.

• Question 835:

  After moving a user's legacy workstation into a new private office that does not have a LAN connection, the technician is unable to connect to a wireless network. Which of the following is the most likely reason?

  A. Missing Wi-Fi adapter
  B. Wi-Fi AP replacement
  C. Hidden Wi-Fi SSID
  D. Incorrect Wi-Fi channel
  A. Missing Wi-Fi adapter

  ---

  Explanation

  The most likely reason is A. Missing Wi-Fi adapter. A Wi-Fi adapter is a device that allows a computer to connect to a wireless network. A legacy workstation may not have a built-in Wi-Fi adapter, or it may have an outdated or incompatible one. If the workstation does not have a Wi-Fi adapter, it will not be able to detect or access any wireless networks, regardless of the location, signal strength, or configuration of the network. To fix this issue, the technician can install a Wi-Fi adapter on the workstation, either internally or externally. An internal Wi-Fi adapter is a card that fits into a slot on the motherboard, while an external Wi-Fi adapter is a device that plugs into a USB port. The technician should choose a Wi-Fi adapter that is compatible with the workstation's operating system, hardware, and wireless standards . The other options are less likely to be the reason for the issue. A Wi-Fi AP replacement means changing the wireless access point that provides the network connection. This may affect the network name, password, or settings, but it should not prevent the workstation from detecting any wireless networks. A hidden Wi-Fi SSID means that the network name is not broadcasted publicly, but it can still be accessed by entering the name manually. A hidden Wi-Fi SSID may make it harder to find the network, but it should not prevent the workstation from detecting other wireless networks. An incorrect Wi-Fi channel means that the network is using a frequency band that is crowded or interfered by other devices. This may affect the network performance or stability, but it should not prevent the workstation from detecting any wireless networks.

• Question 836:

  Which of the following should a technician use to terminate an RJ45 port?

  A. Cable tester
  B. Punchdown tool
  C. Toner probe
  D. Cable stripper
  B. Punchdown tool

  ---

  Explanation

  To terminate an RJ45 port, a technician should use a punchdown tool. This tool is specifically designed to insert and cut (terminate) the wires into a patch panel, keystone jack, or a network surface mount box. The punchdown tool ensures that the wire is properly seated in the terminal block and that the connection is secure. It also trims the excess wire during the termination process, which is not a function that cable testers, toner probes, or cable strippers are designed to perform.

• Question 837:

  A restaurant calls the support line about its 3in (2.5cm) point-of-sale printer that is only printing fully black receipts. Which of the following should the technician check in order to resolve the issue? (Select two).

  A. Power supply
  B. Humidity
  C. Rollers
  D. Fuser
  E. Heating element
  F. Room temperature
  C. Rollers
  E. Heating element

  ---

  Explanation

  The correct answers are

  C. Rollers and

  E. Heating element.

  A 3in (2.5cm) point-of-sale printer is a type of thermal printer that uses heat to print receipts on special thermal paper. The printer has a heating element that heats up the paper as it passes through the rollers, creating black marks on the paper where the heat is applied. The heating element and the rollers are two critical components of the thermal printer that can affect the quality of the printout. If the printer is only printing fully black receipts, it means that the heating element is overheating or malfunctioning, causing the entire paper to turn black. The heating element may need to be replaced or repaired by a technician. Alternatively, the rollers may be dirty or damaged, causing the paper to stick to the heating element and get burned. The rollers may need to be cleaned or replaced by a technician. The other options are not likely to cause the printer to print fully black receipts. The power supply may affect the printer's performance, but it would not cause the heating element to overheat or the rollers to malfunction. The humidity and room temperature may affect the quality of the thermal paper, but they would not cause the entire paper to turn black. The fuser is a component of a laser printer, not a thermal printer, and it has no effect on the point-of-sale printer.

• Question 838:

  A user routinely connects and disconnects multiple devices from a laptop.

  Which of the following options should a technician recommend to facilitate ease of user mobility?

  A. Serial interfaces
  B. Docking station
  C. Network switch
  D. USB hub
  B. Docking station

  ---

  Explanation

  Reasoning: A docking station is designed to provide a central connection point for multiple peripherals, such as monitors, keyboards, mice, and network cables. It allows users to quickly connect or disconnect all devices by simply docking or undocking their laptop, improving mobility and reducing wear and tear on individual ports.

  Practical Example:

  A user with a laptop, external monitors, keyboard, and mouse can use a docking station to connect all devices with a single action, instead of plugging in each device manually.

• Question 839:

  An administrator is replacing a cable that uses a DB9 connector VVhich of the following cables is the administrator replacing?

  A. Parallel
  B. Serial
  C. Optical
  D. USB
  B. Serial

  ---

  Explanation

  A serial cable is a type of cable that can be used to connect devices that use serial communication, which is a method of sending data one bit at a time over a single wire. Serial cables are often used for console access to network devices, such as routers, switches, firewalls, or servers, when other methods of connection, such as SSH (Secure Shell), are not available or not working. A DB9 connector is a type of connector that has nine pins and is commonly used for serial cables. DB stands for D-subminiature, which is a family of connectors that have a D- shaped metal shield and different numbers of pins. DB9 connectors are also known as DE- 9 connectors, as they belong to the E size category of Dsubminiature connectors. DB9 connectors can support various serial standards, such as RS-232, RS-422, or RS-485. A parallel cable is a type of cable that can be used to connect devices that use parallel communication, which is a method of sending data multiple bits at a time over multiple wires. Parallel cables are often used for connecting printers or scanners to computers, but they are not commonly used for network devices or serial connections. An optical cable is a type of cable that can be used to transmit data using light signals over fiber-optic strands. Optical cables can offer high-speed, high-bandwidth, and low- interference data transmission over long distances. Optical cables are often used for network communication, such as Ethernet, or audio/video transmission, such as HDMI or TOSLINK. A USB cable is a type of cable that can be used to connect devices that use the Universal Serial Bus (USB) standard, which is a protocol that allows data and power transmission between devices. USB cables can support various types of devices, such as keyboards, mice, cameras, flash drives, or chargers. USB cables have different versions and connectors, such as USB-A, USB-B, USB-C, or Micro-USB. Therefore, the only cable that uses a DB9 connector is a serial cable.
