The serious exam for people who make models fast and cheap. Optimization and GPU work are almost a third of it, and prompt engineering is only 13%. If you self-host or tune models, nothing else on this list tests that as directly.
Take it if
You self-host, fine-tune or optimize LLMs on GPUs.
Skip it if
You only call hosted APIs. Most of this will not apply to your job.
Before you start
Check yourself against this list first. If something is missing, close that gap before you pay for an exam.
Two to three years with LLMsNVIDIA lists this.
Transformers and fine-tuningNCA-GENL covers the base.
Access to a GPUYou need one to practice optimization.
NVIDIA's page shows both "Coming soon" and a register button, so confirm before you plan around it

GPU acceleration, memory, and distributed parallelism.
Fine-tuning, including parameter-efficient methods such as LoRA.
Prompt engineering at a technical level.
Serving: batching, latency, throughput and monitoring.

Lesson 1 of 4, 17% + 14% of the exam
Performance on GPUs
Almost a third of the exam.
Quantization
Lower precision uses less memory and usually runs faster.
Batching
Shares the GPU across requests.
KV cache
Avoids recomputing attention for earlier tokens.
Why continuous batching helpsNew requests join between generation steps.

Q->>G: Requests 1 and 2 start
G-->>Q: Request 1 finishes
Q->>G: Request 3 joins at once
G-->>Q: Request 2 finishes
Q->>G: Request 4 joins
Common trap
Optimizing without measuring tokens per second first.

NIM
Microservices for deploying foundation models on any cloud or data center.
Tail latency
Rising p99 with flat utilization suggests queueing.
Evaluation
Measure before and after each optimization.
Reading latencyQueue time and compute time point to different fixes.
