AI0-001 Implementing AI Solutions Practice Question
A team is designing a RAG system for a large collection of PDFs. They need to choose document chunking strategies. Which TWO strategies are considered best practices? (Choose two.)
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
✓
Semantic chunking (e.g., sentence or paragraph boundaries)
Semantic chunking preserves natural boundaries, and hierarchical chunking respects document structure, both improving retrieval quality.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Semantic chunking (e.g., sentence or paragraph boundaries)
Why this is correct
Semantic chunking maintains coherence within each chunk, improving embedding quality.
- ✗
Fixed-size chunking with no overlap
Why it's wrong here
Fixed-size chunking splits arbitrarily, often breaking meaningful content across chunks.
- ✓
Hierarchical chunking (sections, subsections)
Why this is correct
Hierarchical chunking preserves document structure, allowing retrieval at appropriate levels.
- ✗
Single chunk per document
Why it's wrong here
Single chunks are too large for long documents, causing information dilution and hitting context limits.
- ✗
Random character-length chunks
Why it's wrong here
Random chunks destroy semantic meaning and reduce retrieval accuracy.
