220-1102 Practice Question: A technician upgrades a Windows 10 workstation's…
This 220-1102 practice question tests your understanding of a technician upgrades a windows 10 workstation's…. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 upgrades a Windows 10 workstation's RAM from 8 GB to 16 GB. After the upgrade, the system boots but applications frequently crash with errors such as 'The instruction at 0x... referenced memory at 0x... The memory could not be read.' The technician has verified that the new RAM is compatible and has reseated the modules. Which of the following should the technician try 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
Best answer
Run Windows Memory Diagnostic
Correct. This built-in tool tests RAM for errors and can identify defective modules.
B
Distractor review
Update the BIOS/UEFI firmware
While a BIOS update can improve memory compatibility, it is not the immediate next step. Memory testing should be performed first.
C
Distractor review
Disable XMP in the BIOS
XMP (Extreme Memory Profile) sets memory timings and speed. If the RAM requires XMP, disabling it may cause instability, but testing the memory is a more logical first step.
D
Distractor review
Run sfc /scannow
System File Checker repairs corrupted system files, but the symptoms point to a hardware memory issue, not system file corruption.
Answer analysis
Why the other options are wrong
Understanding why incorrect options are tempting is as important as knowing the correct answer.
- ✗
Update the BIOS/UEFI firmware
While a BIOS update can improve memory compatibility, it is not the immediate next step. Memory testing should be performed first.
- ✗
Disable XMP in the BIOS
XMP (Extreme Memory Profile) sets memory timings and speed. If the RAM requires XMP, disabling it may cause instability, but testing the memory is a more logical first step.
- ✗
Run sfc /scannow
System File Checker repairs corrupted system files, but the symptoms point to a hardware memory issue, not system file corruption.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

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.

FAQ
Questions learners often ask
What does this 220-1102 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Run Windows Memory Diagnostic — Memory-related errors after a RAM upgrade suggest faulty or incompatible memory modules. The Windows Memory Diagnostic tool can test the RAM for errors. Updating BIOS/UEFI firmware or disabling XMP might be considered later, but the immediate next step is to test the memory. Running sfc /scannow checks system files, which is less likely to be the cause here.
What should I do if I get this 220-1102 question wrong?
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related 220-1102 NAT questions on configuration and troubleshooting.
