220-1102 Practice Question: A technician is troubleshooting a Windows 10…
This 220-1102 practice question tests your understanding of a technician is troubleshooting a windows 10…. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A technician is troubleshooting a Windows 10 computer that randomly reboots without warning. Event Viewer shows event ID 41 (Kernel-Power) with no other critical errors. The technician has already updated drivers and verified the power supply. What 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 RAM modules
RAM issues typically cause specific errors like blue screens or application crashes, not random restarts with only event ID 41.
B
Distractor review
Disable automatic restart on system failure
This would prevent the system from restarting but would not address the underlying cause; it is a temporary workaround, not a solution.
C
Distractor review
Run the Windows Memory Diagnostic tool
Memory diagnostics are useful for memory-related crashes but are not the most likely cause for random restarts without memory errors.
D
Best answer
Check the CPU temperature
Overheating CPUs can cause sudden shutdowns or restarts without warning. Checking temperature is the logical next step after verifying power and drivers.
Answer analysis
Why the other options are wrong
Understanding why incorrect options are tempting is as important as knowing the correct answer.

Common exam trap
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Technical deep dive
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.

The technician completes the update on a file server and verifies the server is functioning normally. According to change management best practices, what documentation should the technician complete?
Question 2
A company's change management policy requires all server changes to be approved by the Change Advisory Board (CAB). A technician discovers that a critical database server's operating system needs a security patch to comply with a new regulatory requirement that takes effect in one week. The patch has a known risk of causing service downtime. The next scheduled CAB meeting is in two weeks. What should the technician do FIRST?

FAQ
Questions learners often ask
What does this 220-1102 question test?
CIDR notation defines the prefix length.
What is the correct answer to this question?
The correct answer is: Check the CPU temperature — Random reboots with a Kernel-Power event ID 41 often indicate an overheating issue. When the CPU reaches a critical temperature, the system may shut down or restart suddenly to prevent damage. The technician should check the CPU temperature using BIOS/UEFI or third-party tools. Replacing RAM is unlikely if there are no memory-related errors. Disabling automatic restart would mask the symptom but not solve the problem. Running a memory diagnostic is a valid step but is less common for random restarts compared to overheating; overheating should be checked first since the technician has already covered driver and power supply issues.
What should I do if I get this 220-1102 question wrong?
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related 220-1102 subnetting questions on CIDR, address ranges, and subnet selection.
