- A
Code review
Why wrong: Code review is a manual inspection by others, not using a debugger.
- B
Step-through execution
Why wrong: Step-through moves line by line, but breakpoints are used to pause at specific lines.
- C
Logging
Why wrong: Logging involves writing messages to a file, not pausing execution.
- D
Breakpoint inspection
Breakpoints halt execution for variable inspection.

FC0-U61 Software Development Practice Question
This FC0-U61 practice question tests your understanding of software development. 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 developer is trying to find why a program is producing incorrect output. The developer runs the program with a debugging tool, sets a breakpoint at a specific line, and examines the values of variables at that point. Which debugging technique is being used?
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
✓
Breakpoint inspection
Option D is correct because the developer is using breakpoint inspection, a debugging technique where execution is paused at a specific line of code (the breakpoint) to examine variable values at that exact moment. This allows the developer to inspect the program's state without stepping through each subsequent line, directly identifying why incorrect output occurs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse breakpoint inspection with step-through execution, but step-through involves actively moving through code line by line, whereas breakpoint inspection pauses at a single point for variable examination without stepping.
Detailed technical explanation
How to think about this question
Breakpoint inspection relies on the debugger's ability to halt the program's execution at a specific instruction address, typically by replacing the instruction with a software interrupt (e.g., INT 3 on x86) or using hardware breakpoints. In real-world scenarios, developers use conditional breakpoints (e.g., break when a variable equals a specific value) to efficiently isolate bugs in loops or complex logic without manual stepping.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the FC0-U61 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
