AI0-001 AI Implementation and Operations Practice Question
A company is deploying a fraud detection model that must return predictions within 100ms to avoid transaction delays. The team is deciding between batch and real-time inference. Which factor most strongly supports a real-time inference architecture?
⚠ Common exam trap
CompTIA often tests the misconception that batch inference is always cheaper or more efficient, but the trap here is that latency requirements (under 100ms) force a real-time architecture regardless of cost or data volume.
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
✓
The application requires immediate feedback for each transaction
Real-time inference is required when the application must return predictions within strict latency bounds (e.g., 100ms) to avoid transaction delays. The need for immediate feedback per transaction directly aligns with a real-time architecture, where each request is processed individually as it arrives, rather than waiting for a batch window. Batch inference would introduce unacceptable latency because it processes groups of records on a schedule, not on-demand.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The model requires large amounts of historical data for each prediction
Why it's wrong here
Real-time inference typically uses recent data, not large historical context.
- ✓
The application requires immediate feedback for each transaction
Why this is correct
Real-time inference delivers low-latency predictions for each request.
- ✗
The infrastructure budget is limited and must be optimized
Why it's wrong here
Batch is often cheaper, but latency trumps cost here.
- ✗
The model can be retrained weekly using gathered data
Why it's wrong here
Retraining frequency is separate from inference mode.
