A technician is troubleshooting a laser printer that produces pages with vertical black streaks down the length of each page. The technician has already replaced the toner cartridge and the imaging drum with new OEM parts. A test page printed from the printer's control panel also shows the streaks. Which of the following printer components is MOST likely causing this issue?

A technician is troubleshooting a laser printer that produces pages with vertical black streaks down the length of each page. The technician has already replaced the toner cartridge and the imaging drum with new OEM parts. A test page printed from the printer's control panel also shows the streaks. Which of the following printer components is MOST likely causing this issue?

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Best answer

Fuser assembly

A damaged or dirty fuser roller can leave toner residue on the page, creating vertical streaks that run the length of the paper. This is a common issue after the toner and drum have been ruled out.

B

Distractor review

Transfer roller

A faulty transfer roller typically causes uneven or weak image transfer, such as light or mottled areas, rather than distinct vertical black streaks.

C

Distractor review

Primary corona wire

The corona wire charges the drum. A dirty or damaged corona wire usually causes light horizontal bands or overall poor image density, not solid black streaks.

D

Distractor review

Pickup roller

The pickup roller feeds paper into the printer. A worn or dirty pickup roller causes paper jams or misfeeds, not print quality defects like streaks.

Common exam trap

Common exam trap: OSPF can fail even when IP connectivity looks correct

OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.

Technical deep dive

How to think about this question

OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.

KKey Concepts to Remember

  • OSPF neighbours must agree on key parameters.
  • Router ID selection can affect neighbour relationships and LSDB output.
  • OSPF cost influences the preferred path.
  • A route can appear in OSPF information but not become the installed route.

TExam Day Tips

  • Check area mismatch first when OSPF adjacency fails.
  • Review passive interfaces when a network is advertised but no neighbour forms.
  • Use show ip ospf neighbor and show ip route clues carefully.

Question 1

A user reports intermittent network connectivity on a desktop computer. The technician observes that the Ethernet link light on the NIC turns off for a few seconds and then turns back on. The cable passes a wiremap test, the switch port is verified good with another device, and the NIC driver is updated. The issue occurs more frequently when the computer's case fan runs at high speed. Which of the following is the MOST likely cause?

Question 2

A workstation is unable to connect to the internet. The technician runs the 'ipconfig' command and sees the IPv4 address is 169.254.15.200 with a subnet mask of 255.255.0.0. The workstation can ping other devices on the local subnet but cannot ping the default gateway or any external addresses. Which TWO actions should the technician take to resolve this issue? (Select two.)

Question 3

A workstation is connected to a managed switch. It obtains a valid IP address (192.168.10.50) from the DHCP server, but it cannot ping the default gateway (192.168.10.1). The link light on both the workstation NIC and the switch port are solid green. Other workstations on the same switch CAN ping the default gateway successfully. The technician accesses the switch management interface and finds that the workstation's port is configured as an access port on VLAN 10. The default gateway is located on VLAN 20. An inter-VLAN router is configured but not explicitly allowing VLAN 10 access to VLAN 20. Which of the following is the MOST likely cause of the problem?

Question 4

A company develops a web application that relies on a custom library available only for a specific Linux distribution. They want to deploy the application in the cloud with minimal administrative overhead, but they need full control over the software stack, including the ability to install the custom library and configure the web server. Which cloud service model BEST meets these requirements?

Question 5

A company has a legacy virtual machine running on a deprecated hypervisor (Hyper-V). They want to migrate this VM to a new hypervisor (VMware vSphere) hosted in a private cloud while preserving the VM's configuration, installed applications, and data. The migration must be performed with minimal downtime. Which of the following methods is MOST appropriate?

Question 6

A company hosts a critical database on a virtual machine in a public cloud. The database requires persistent storage that must be retained even if the VM is terminated. The storage must also be accessible from multiple VMs simultaneously for a future high-availability configuration. Which type of cloud storage BEST meets these requirements?

FAQ

Questions learners often ask

What does this 220-1101 question test?

OSPF neighbours must agree on key parameters.

What is the correct answer to this question?

The correct answer is: Fuser assembly — Vertical black streaks extending the full length of the page typically indicate a problem with the fuser assembly. The fuser uses heat and pressure to melt toner onto the paper. If the fuser roller is scratched or has a defect, it can transfer toner onto the paper in a repeating pattern. The transfer roller usually causes uneven toner transfer, not consistent streaks. The corona wire (or primary charge roller) would cause light or dark areas, not distinct streaks. The pickup roller is related to paper jams, not image quality.
