Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A technician is troubleshooting a workstation that loses network connectivity intermittently, specifically when the user runs CPU-intensive applications like video rendering. The link light on the network interface card (NIC) turns off during these episodes. The technician has already replaced the Ethernet cable with a known-good cable and switched the workstation to a different port on the same switch, but the problem persists. The same port and cable work fine when tested with a laptop. The workstation has a recently installed high-end graphics card and a 400W power supply that came with the case. Which of the following is the MOST likely cause?
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
Faulty network card
A faulty NIC could cause intermittent connectivity, but the direct correlation with CPU load and the link light turning off points toward a power problem rather than a defective NIC. If the NIC were faulty, it would likely fail regardless of load.
B
Best answer
Insufficient power supply wattage
When the system is under heavy load (CPU and GPU intensive tasks), the power draw spikes. An underpowered PSU may cause voltage droop on the motherboard rails, causing the integrated or add-on NIC to lose power or reset, dropping the link. Upgrading the PSU to a higher wattage unit would resolve the issue.
C
Distractor review
Outdated network driver
An outdated driver could cause software-level disconnects, but it would not typically cause the link light on the NIC to turn off. A driver issue might result in an unresponsive interface but the physical link usually remains up.
D
Distractor review
Electromagnetic interference from the GPU
Electromagnetic interference (EMI) from the GPU could cause data corruption or reduced throughput, but it is unlikely to cause the link light to turn off completely. The link light indicates a physical layer connection; EMI would not typically break that connection.
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: Insufficient power supply wattage — The issue is tied to CPU/graphics load, which increases power draw. The 400W PSU may be insufficient to handle the peak power demand, causing voltage drops that affect the NIC or motherboard components. The NIC may reset due to undervoltage, dropping the link. The cable and switch port are ruled out. The NIC itself is unlikely to be load-sensitive unless it's overheating, but the link light turning off suggests a power or reset issue. An outdated driver could cause disconnects but typically not a hard link loss.
