A network technician is troubleshooting a network laser printer that is intermittently dropping off the network. The printer has a static IP address of 192.168.1.50. The technician can sometimes ping the printer, but often the ping times out. The printer's network configuration page shows it is connected at 100 Mbps, half-duplex. The switch port to which the printer is connected supports up to 1000 Mbps and is set to auto-negotiate. Which of the following is the MOST likely cause of the intermittent connectivity?
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
Distractor review
The printer's network interface card (NIC) is faulty and needs to be replaced.
While a faulty NIC is possible, the specific symptom of half-duplex combined with auto-negotiation on the switch strongly points to a duplex mismatch as the cause of intermittent connectivity. A faulty NIC would likely cause a total failure or continuous errors, not a mismatch scenario.
B
Distractor review
The switch port is configured for 1000 Mbps, but the printer only supports 100 Mbps, causing a speed mismatch.
Speed mismatches typically prevent a link from establishing at all (no link lights). Since the printer is connected at 100 Mbps, the auto-negotiation succeeded at the speed level. The issue is with the duplex setting, not the speed.
C
Distractor review
The printer is configured with a static IP that conflicts with another device on the network.
An IP conflict would cause consistent connectivity failures, not intermittent ones, and would typically be indicated by a 'duplicate IP' error in logs. The symptom of high packet loss without a definite IP conflict points to a physical/link issue.
D
Best answer
The duplex settings are mismatched between the printer and the switch port.
A duplex mismatch occurs when one device is manually set to half-duplex and the other is set to auto-negotiate. This leads to a high number of collisions and frame errors, causing intermittent connectivity and packet loss.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

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?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: The duplex settings are mismatched between the printer and the switch port. — Duplex mismatch is a common network issue that occurs when one device (the printer) is forced to a specific duplex setting (half-duplex) while the other device (the switch port) is set to auto-negotiate. When a device is set to half-duplex and the other is set to auto-negotiate, the auto-negotiation process typically defaults to half-duplex as well, but it can also lead to a situation where the switch thinks it is using full-duplex while the printer uses half-duplex. This causes many collisions and errors, resulting in high packet loss and intermittent connectivity. The solution is to set the printer's NIC to auto-negotiate (or manually set both sides to the same speed/duplex), not just change the cable or check the speed setting without addressing duplex. Fixing the duplex mismatch will resolve the issue.
