Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A technician installs a new Gigabit Ethernet NIC in a workstation to replace a faulty onboard NIC. After installation, the technician connects the Ethernet cable from the switch to the new NIC. The link light on the new NIC is off. The technician swaps the cable with a known-good cable, but the light remains off. The new NIC is detected in Device Manager with no errors. The technician tries the new NIC in another workstation and it works fine. Which of the following should the technician do NEXT?
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
Replace the switch
Replacing the switch is an extreme and unnecessary step. The switch likely works for other devices, and the issue is isolated to this specific port or its configuration.
B
Best answer
Check the switch port configuration for port security or error-disable state
Port security features can cause a port to be error-disabled when a MAC address violation occurs, such as when a new NIC with an unknown MAC is connected. Checking the switch's interface status and resetting the port if needed will likely restore connectivity.
C
Distractor review
Update the NIC driver to the latest version
The NIC is detected in Device Manager without errors, indicating the driver is functioning. A driver issue would not typically cause the link light to be off; it would more likely cause connectivity problems after the link is established.
D
Distractor review
Change the NIC's duplex setting in Windows
Duplex settings cannot be configured until a link is established. Additionally, mismatched duplex settings usually result in link lights being on with high error rates, not a completely absent link light.
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: Check the switch port configuration for port security or error-disable state — Since the NIC works in another workstation and the cable is known-good, the issue is likely related to the switch port configuration. The link light being off suggests the port may be in an error-disabled state due to security violations, such as port security with a MAC address limit. When the new NIC (with a different MAC address) was connected, the switch may have disabled the port. Checking the switch port status and configuration, and resetting the error-disable state if necessary, is the appropriate next step. Option A is premature because the switch may be functioning correctly for other devices. Option C is not likely because the NIC is detected and the driver is working. Option D is not possible because duplex settings cannot be changed without a link.
