AI-103 Implement Generative AI And Agentic Solutions Practice Question
When implementing Retrieval-Augmented Generation (RAG) using Azure AI Search and Azure OpenAI, which THREE strategies help optimize chunk retrieval relevance and reduce noise? (Choose three)
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
✓
Configure hybrid search combining vector embeddings and keyword full-text search.
Hybrid search (combining vectors and keywords), semantic ranking, and appropriate chunk sizing are proven strategies for optimizing RAG relevance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure hybrid search combining vector embeddings and keyword full-text search.
Why this is correct
Hybrid search leverages the strengths of both dense vector search and sparse keyword search to retrieve the most relevant chunks.
- ✗
Store all corporate documents in a single unindexed raw text blob without metadata fields.
Why it's wrong here
Unindexed raw text blobs without metadata prevent efficient filtering and targeted retrieval.
- ✗
Set the embedding model dimensions to the lowest possible setting to maximize retrieval speed.
Why it's wrong here
Lower dimensions reduce semantic expressiveness and typically degrade retrieval accuracy in vector search.
- ✓
Implement document chunking strategies with appropriate overlap to preserve context across boundaries.
Why this is correct
Chunking with overlap ensures that sentences spanning boundary lines are not split apart, retaining contextual coherence.
- ✓
Enable semantic ranking to re-rank search results using deep learning models.
Why this is correct
Semantic ranking significantly improves precision by re-ranking initial search results based on deep semantic meaning.
