AI0-001 AI Concepts and Foundations Practice Question
A company uses a pre-trained language model for a legal document classification task. They have limited labeled data (500 documents). Which strategy is MOST effective for adapting the model to this domain?
⚠ Common exam trap
CompTIA often tests the misconception that more data is always better (trap of Option C) or that starting from scratch is safer (trap of Option B), when in fact transfer learning via fine-tuning is the standard approach for low-resource NLP tasks.

Correct answer & explanation
✓
Fine-tune the pre-trained model on the 500 labeled documents.
Fine-tuning a pre-trained language model on 500 labeled legal documents is the most effective strategy because it leverages the model's existing knowledge of language structure and general semantics, requiring only a small amount of domain-specific data to adapt to the legal classification task. This approach avoids the high data requirements of training from scratch and outperforms rule-based or augmentation-only methods by directly optimizing the model's weights for the target domain.
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 a rule-based keyword matching system instead.
Why it's wrong here
Rules may not capture all variations in legal language.
- ✗
Train a new model from scratch on the 500 documents.
Why it's wrong here
500 documents are insufficient for training a large model from scratch.
- ✗
Apply extensive data augmentation to increase dataset size.
Why it's wrong here
Augmentation can help, but fine-tuning a pre-trained model is more effective.
- ✓
Fine-tune the pre-trained model on the 500 labeled documents.
Why this is correct
Correct; transfer learning works well with small labeled datasets.
