AI0-001 AI Models and Data Engineering Practice Question
Which TWO are best practices for versioning machine learning models? (Choose 2)
⚠ Common exam trap
CompTIA often tests the misconception that versioning is only about file naming or storing the binary, when in fact it requires a comprehensive metadata and code tracking system to ensure reproducibility and traceability.
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
✓
Tag each model with training date, hyperparameters, and performance metrics
Tagging each model with training date, hyperparameters, and performance metrics creates a reproducible audit trail. This practice aligns with MLOps principles, enabling teams to trace model behavior back to specific training runs and compare versions objectively.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use the same model version for all deployments
Why it's wrong here
Different deployments may need different versions.
- ✓
Tag each model with training date, hyperparameters, and performance metrics
Why this is correct
Metadata enables comparison and audit.
- ✓
Use a version control system (e.g., Git) for model code and configuration
Why this is correct
Git tracks changes and enables rollback.
- ✗
Store only the final model binary without metadata
Why it's wrong here
Lacks context for reproducibility.
- ✗
Manually rename model files with version numbers
Why it's wrong here
Prone to human error and lacks automation.
