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
✓
Balance replica and partition counts based on your query throughput and index size requirements
Best practices for Azure AI Search include monitoring resource utilization, right-sizing replicas and partitions, and leveraging vector compression (scalar quantization).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Balance replica and partition counts based on your query throughput and index size requirements
Why this is correct
Proper shard and replica planning optimizes cost and query performance.
- ✗
Store all raw PDF files inside the vector float32 array fields
Why it's wrong here
Vector fields store numeric embeddings, not raw PDF document binaries.
- ✓
Use scalar quantization to reduce memory footprint and improve HNSW search throughput
Why this is correct
Quantization reduces memory usage and speeds up vector searches.
- ✓
Monitor search unit resource utilization (CPU, memory, storage) using Azure Monitor
Why this is correct
Monitoring ensures services are appropriately scaled to prevent throttling or timeouts.
- ✗
Deploy all indexes on the Free tier to eliminate infrastructure costs
Why it's wrong here
The Free tier has severe resource and feature limitations unsuitable for production.
