The monitor's firmware is outdated.

Question 2

A company's remote employees use VPN to connect to the office network. Recently, some users report that they can connect to the VPN but cannot browse the internet or access internal servers by name, though they can ping internal IP addresses. The VPN is configured to push DNS settings. Which protocol is likely misconfigured on the VPN server?

Accepted Answer

DNS. (DNS) because the users can connect to the VPN and ping internal IP addresses, but cannot resolve hostnames to IP addresses. This indicates that the DNS resolution is failing, which is caused by the VPN server not correctly pushing DNS server settings to the VPN clients. Without proper DNS configuration, clients cannot translate domain names (e.g., internal server names or internet URLs) into IP addresses, even though the network layer connectivity (ping to IPs) works.

The printer's platen roller is worn.

Answer

The label stock is expired.

Question 7

A user in a law office reports that their laser printer prints documents with faint text and light images. The toner cartridge is new, and the printer has sufficient toner. Which component should you inspect or replace first?

Accepted Answer

Drum unit. Faint print with a new toner cartridge often points to a worn or damaged drum. The drum is part of the toner cartridge or a separate unit, and if it is worn, it cannot hold a proper charge, resulting in light output. Replacing the drum or the entire cartridge usually solves the problem.

Answer

Transfer roller

Answer

Fuser assembly

Answer

Pickup rollers

Question 8

A user reports that their laser printer prints a blank page after every print job. The document itself prints correctly, but an extra blank sheet follows. What is the most likely cause?

Accepted Answer

The printer driver is set to print a separator page. An extra blank page after a print job is often caused by a setting in the printer driver or application that adds a separator page. This is common when 'Print separator page' is enabled. Checking the driver settings and disabling any separator page option usually resolves it.

Answer

The printer has a low toner cartridge

Answer

The fuser is malfunctioning

Answer

The paper size setting is wrong

Question 9

A technician is configuring a mobile hotspot on a smartphone to provide internet access to a laptop. The laptop connects to the hotspot's Wi-Fi network but cannot access the internet. The smartphone has a cellular data connection. Which of the following should the technician check first?

Accepted Answer

The smartphone's mobile data is enabled. Mobile hotspots require cellular data to be enabled; if data is off, the hotspot broadcasts a Wi-Fi signal but no internet passes through. This tests basic troubleshooting of hotspot functionality and the dependency on cellular data.

Answer

The laptop's IP address configuration

Answer

The laptop's firewall settings

Answer

The smartphone's Wi-Fi is turned on

Question 10

A small office has an inkjet printer that produces prints with horizontal white lines across the page. The lines appear in different positions on each print. Which step should the technician take first?

Answer

The printhead assembly.

Answer

The ink cartridges.

Answer

The printer's main logic board.

Question 12

A technician is troubleshooting a color laser printer that prints documents with a yellow tint on all pages. The yellow toner cartridge is full, and the other colors are at normal levels. Which component is the most likely cause?

Accepted Answer

The yellow toner cartridge's shutter is stuck open.. A yellow tint across all pages suggests the yellow toner is being applied continuously. This could be due to a faulty yellow toner cartridge that leaks toner, or a stuck shutter. In some cases, the imaging drum for yellow may be damaged, but the cartridge itself is the first suspect.

Question 13

A technician is setting up a new printer on a network. The printer has a static IP address of 192.168.1.50, but users cannot ping it from their workstations. The workstations are on the 192.168.1.0/24 subnet. What should the technician check first?

Accepted Answer

Verify the switch port status and cable connection.. Since the printer and workstations are on the same subnet, the issue is likely at Layer 2 or Layer 1. The first step is to verify the physical connection and link status on the switch port, as a bad cable or disabled port would prevent communication.

Answer

Check the printer's default gateway setting.

Answer

Change the printer's IP address to a DHCP address.

Answer

Reboot the router.

Question 14

A technician is deploying a new laser printer in a medical office. After installation, the printer prints a test page correctly, but when users print from their workstations, the output is garbled with random characters. What is the most likely cause?

Accepted Answer

The printer driver is incorrect or corrupt. Garbled output from a printer that works on a test page but not from workstations usually indicates a driver mismatch. The test page uses the printer's internal firmware, while user print jobs rely on the installed driver. Installing the correct driver for the printer model and operating system resolves the issue.
