FC0-U71 Practice Question: Refer to the exhibit
Exhibit
Refer to the exhibit. Error: The application encountered an unexpected error and must close. Application: inventory.exe Version: 2.1.0 Module: stock.dll Address: 0x00401234 Faulting module: msvcrt.dll Fault address: 0x77C12345
Refer to the exhibit. What is the most likely cause of the application crash?
⚠ Common exam trap
Many exam-takers confuse a DLL entry point error with general system resource issues like low RAM or antivirus interference, but the specific mention of a function in msvcrt.dll points directly to a corrupted or missing runtime library.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A necessary system runtime library (msvcrt.dll) is corrupted or missing.
The error message indicates that the application cannot find the entry point for a function in msvcrt.dll, which is a critical system runtime library for C/C++ applications. This typically occurs when the DLL is corrupted, missing, or of an incorrect version, preventing the application from loading necessary functions. Since the error specifically references msvcrt.dll, the most likely cause is that this runtime library is corrupted or missing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A necessary system runtime library (msvcrt.dll) is corrupted or missing.
Why this is correct
The faulting module is msvcrt.dll, a critical system file, indicating a system-level issue.
- ✗
The computer does not have enough RAM to run the application.
Why it's wrong here
Insufficient RAM typically causes out-of-memory errors, not a crash in a system DLL.
- ✗
The antivirus software is blocking the application from executing.
Why it's wrong here
Antivirus blocks would typically prevent launch, not cause a crash in a system DLL at runtime.
- ✗
The application inventory.exe is incompatible with the operating system.
Why it's wrong here
The application version is specified, but the faulting module is a system DLL, not the application itself.
