A technician is replacing a failed power supply in a desktop computer. The new power supply is the same form factor and wattage as the original. After installing it, the computer powers on for a few seconds then shuts down. The technician has already verified that all power connectors are securely attached and that the power supply passes the paperclip test when disconnected from the motherboard. Which of the following should the technician check 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.
Best answer
The CPU fan is connected to the correct header.
If the CPU fan is not connected to the dedicated CPU_FAN header, the motherboard may trigger a shutdown to protect the CPU from overheating. The fan must be on the correct header for the motherboard to detect its speed.
Distractor review
The power supply voltage selector switch.
Most modern power supplies have auto-voltage switching or a switch that is set correctly by default. This is rarely the cause of shutdowns and would likely prevent the system from powering on at all.
Distractor review
The motherboard's capacitors for bulging.
Bulging capacitors can cause instability, but they are not the most likely cause after a PSU replacement. The system was working before the PSU failed, so capacitors are usually not an issue.
Distractor review
The RAM modules are seated properly.
Improperly seated RAM would typically cause the system to fail to POST or produce beep codes, not power on for a few seconds and then shut down.
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 CPU fan is connected to the correct header. — Many motherboards have a protection feature that shuts down the system if the CPU fan is not detected, to prevent overheating. Even though the fan may be spinning, if it is connected to the wrong header or not connected to the CPU_FAN header, the motherboard may interpret it as a fan failure. The paperclip test confirms the PSU itself works. The voltage selector (B) is typically auto-switching or set correctly for the region. Bulging capacitors (C) would likely cause intermittent issues but not a consistent shutdown after a few seconds. RAM seating issues (D) would typically cause a no-POST condition or beep codes, not a power cycle after a few seconds.
