Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A technician is troubleshooting a desktop computer that will not boot. The motherboard has a 7-segment debug LED that displays code '55'. According to the motherboard manual, this code indicates a memory initialization error. The technician has already reseated the RAM, tested each stick individually in different slots, and replaced the RAM modules with known good ones. The computer still displays the same code. Which of the following components is the MOST likely cause of the 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
Distractor review
The motherboard is defective
While a defective motherboard is possible, the memory controller is in the CPU. The technician should first replace the CPU before assuming the motherboard is faulty.
B
Best answer
The CPU is faulty or has bent pins
The memory controller resides inside modern CPUs. A damaged CPU can prevent memory initialization, even with known good RAM.
C
Distractor review
The power supply is not delivering adequate voltage to the RAM slots
A power supply issue would typically cause the system to not power on at all or to shut down unexpectedly, not produce a specific memory error code.
D
Distractor review
The CMOS battery needs to be replaced
A depleted CMOS battery causes loss of BIOS settings but does not prevent memory initialization. The system would still be able to train RAM.
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 is faulty or has bent pins — The debug code points to memory initialization failure. Since the technician has ruled out the RAM sticks and slots through exhaustive testing, the next most likely cause is the CPU. In modern systems, the memory controller is integrated into the CPU. If the CPU is faulty, it cannot properly communicate with RAM, leading to the memory error. The motherboard (A) is still a possibility, but the CPU is a more probable cause after RAM testing. The power supply (C) would produce different symptoms, such as no power or unexpected shutdowns. The CMOS battery (D) affects BIOS settings retention but does not cause memory initialization errors.
