FC0-U71 Software Development Concepts Practice Question
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?
⚠ Common exam trap
Candidates often 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.
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
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Code review
Why it's wrong here
Code review is a manual inspection by others, not using a debugger.
- ✗
Step-through execution
Why it's wrong here
Step-through moves line by line, but breakpoints are used to pause at specific lines.
- ✗
Logging
Why it's wrong here
Logging involves writing messages to a file, not pausing execution.
- ✓
Breakpoint inspection
Why this is correct
Breakpoints halt execution for variable inspection.
