DA0-002 Data Governance Practice Question
A data team is communicating findings from a machine learning model that predicts equipment failure. The model has high accuracy but low recall. Which of the following statements is the most accurate way to communicate the model's performance to the maintenance team?
⚠ Common exam trap
CompTIA often tests the confusion between accuracy and recall; candidates mistakenly assume high accuracy implies high recall, but accuracy can be high even with low recall if the class imbalance is severe (e.g., many non-failure cases dominate the metric).

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
✓
"The model has a high precision but low recall, so it misses many failures."
It directly states that the model has high precision but low recall, which means that when the model predicts a failure, it is likely correct (few false positives), but it fails to identify many actual failures (many false negatives). This is the most accurate way to communicate the trade-off to the maintenance team, as it clearly indicates that the model will miss some failures despite its high accuracy.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
"The model has a high precision, so when it alerts, it is usually correct, but it may miss some failures."
Why it's wrong here
Incorrect. 'May miss some' downplays the severity of low recall; it misses many.
- ✗
"The model rarely misses a failure, but may have false positives."
Why it's wrong here
Incorrect. Low recall means it misses many failures; this statement describes high recall.
- ✓
"The model has a high precision but low recall, so it misses many failures."
Why this is correct
Correct. This accurately communicates the trade-off between precision and recall.
- ✗
"The model is highly reliable and catches almost all failures."
Why it's wrong here
Incorrect. Low recall means it misses many failures, so it does not catch almost all.
