220-1102 Practice Question: That a critical line-of-business application…
This 220-1102 practice question tests your understanding of that a critical line-of-business application…. 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 user reports that a critical line-of-business application crashes intermittently with an exception code 0xc0000005 (Access Violation) in the Event Viewer. The technician has already updated all drivers, installed Windows updates, and ran System File Checker (SFC), which found no corruption. Which step should the technician take NEXT to resolve 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
Reinstall the application in compatibility mode for an older version of Windows
Compatibility mode is useful for legacy applications but is not the primary step here. The issue is likely hardware or memory-related, not a compatibility problem.
B
Best answer
Run the Windows Memory Diagnostic tool to test for faulty RAM
Access violation errors are frequently caused by defective RAM. Running the Windows Memory Diagnostic tool can identify memory issues that lead to crashes.
C
Distractor review
Disable User Account Control (UAC) to allow the application unrestricted access
Disabling UAC is not a recommended troubleshooting step and would reduce security. It is unlikely to resolve a memory access violation.
D
Distractor review
Perform a System Restore to revert the system to a state before the issue started
System Restore might help if a recent change caused the issue, but the problem is intermittent and driver/update changes have already been checked. Memory diagnostics are more appropriate.

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.

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 the Windows Memory Diagnostic tool to test for faulty RAM — The 0xc0000005 error typically indicates an access violation, often caused by faulty memory, incompatible application settings, or corrupted application dependencies. Since driver and system file integrity checks were completed, the next logical step is to test the system's physical memory using Windows Memory Diagnostic, as bad RAM can cause random access violations.
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.
