- A
Export the model to ONNX format and use a batch processing pipeline
Why wrong: ONNX is for model interchange, not serving; batch processing is not real-time.
- B
Use gRPC streaming for all inference requests
Why wrong: gRPC is efficient but not the default choice for simple request/response inference; REST is more straightforward.
- C
Run the model directly on the client device
Why wrong: Device deployment may not scale centrally and is not a server-side API solution.
- D
Deploy the model as a REST API endpoint using a containerized inference server
REST APIs are stateless and easily scalable with load balancers and container orchestration.

AI0-001 AI Infrastructure and Technologies Practice Question
This AI0-001 practice question tests your understanding of ai infrastructure and technologies. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An ML engineer wants to deploy a model as a REST API that can scale to handle thousands of inference requests per second. Which serving approach is most appropriate?
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
✓
Deploy the model as a REST API endpoint using a containerized inference server
Option D is correct because deploying the model as a REST API endpoint using a containerized inference server (e.g., TensorFlow Serving, TorchServe, or NVIDIA Triton Inference Server) is the most appropriate approach for handling thousands of inference requests per second. These servers are designed for high-throughput, low-latency serving, support horizontal scaling via load balancers, and provide built-in batching and model versioning. REST APIs are stateless and can be easily integrated with existing web infrastructure, making them ideal for production-scale inference.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between serving infrastructure (REST API with containerized server) and data processing pipelines (batch) or communication protocols (gRPC), leading candidates to confuse a transport mechanism or batch method with a scalable serving architecture.
Detailed technical explanation
How to think about this question
Containerized inference servers like NVIDIA Triton Inference Server support dynamic batching, which groups multiple inference requests into a single batch to maximize GPU utilization and throughput, while still exposing a REST API endpoint. Under the hood, these servers use model-specific optimizations (e.g., TensorRT for NVIDIA GPUs) and can automatically scale replicas using Kubernetes Horizontal Pod Autoscaler based on CPU/memory or custom metrics like requests per second. A real-world scenario is a recommendation system serving millions of users per day, where the inference server must handle traffic spikes without manual intervention.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the AI0-001 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
