Exam Tactics¶

Question Strategy¶

1. Read Carefully: Identify the specific NVIDIA tool or technology referenced
2. Eliminate: Remove answers that use incorrect tools for the scenario
3. Think NVIDIA-First: Prefer NVIDIA solutions (NeMo, TensorRT-LLM, NIM) over generic alternatives
4. Consider Constraints: Pay attention to GPU memory, latency, and cost requirements
5. Production Focus: Prefer scalable, production-ready approaches

Time Management¶

• ~1.7-2 minutes per question average
• Flag and move: Don't spend more than 3 minutes on any question
• Reserve 15-20 minutes for reviewing flagged questions
• Quick wins first: Answer confident questions to build momentum

Common Patterns in Questions¶

• "Most efficient method" - Think about the specific resource constraint
• "Best approach for production" - Think NIM, Triton, monitoring
• "Optimize for latency" - Think quantization, batching, TensorRT-LLM
• "Reduce training cost" - Think PEFT methods, mixed precision
• "Improve RAG quality" - Think re-ranking, hybrid search, chunking

Common Pitfalls¶

Study Mistakes¶

• Memorizing API syntax instead of understanding architecture concepts
• Skipping hands-on practice with NVIDIA tools
• Not understanding when to use NeMo vs TensorRT-LLM vs NIM
• Focusing only on training and ignoring inference optimization
• Not practicing with actual GPU hardware

Exam Mistakes¶

• Choosing generic open-source solutions over NVIDIA-specific tools
• Not considering GPU memory constraints in architecture decisions
• Confusing data parallelism with tensor parallelism
• Overlooking quantization as an optimization strategy
• Not reading the full question including constraints and requirements

Conceptual Confusions to Avoid¶

• LoRA vs full fine-tuning tradeoffs (memory, quality, speed)
• Static vs continuous batching performance implications
• Tensor parallelism (for latency) vs data parallelism (for throughput)
• Pre-training vs fine-tuning vs inference optimization
• RAG vs fine-tuning for domain knowledge (when to use each)

Progress Tracking¶
