FC0-U71 Practice Question: A software application is experiencing…
A software application is experiencing performance degradation. The team suspects a memory leak. Which development practice should be used to identify the source of the leak?
⚠ Common exam trap
Candidates often confuse debugging (step-by-step logic inspection) with profiling (runtime performance and memory analysis), assuming any performance issue can be solved by stepping through code, but memory leaks require heap analysis tools.
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
✓
Profiling
Profiling is the correct practice because it involves monitoring the application's runtime behavior, including memory allocation and garbage collection. A memory profiler can track object creation and retention, pinpointing which objects are not being released and causing the leak. This is the standard approach for diagnosing memory leaks in languages like Java or C#.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Unit testing
Why it's wrong here
Unit tests check functionality, not memory allocation over time.
- ✗
Debugging
Why it's wrong here
Debugging helps with logic errors but is not designed for memory leak detection.
- ✓
Profiling
Why this is correct
Profiling tools track resource usage, including memory allocation, to identify leaks.
- ✗
Code review
Why it's wrong here
Code review is manual and may not catch runtime memory leaks.
