The 5 Exam Domains (Know the Weights)
Your study time should roughly match these domain weights. Core ML Knowledge is the largest - don't skip it.
Core Topics
- •Neural network fundamentals: layers, activation functions, backpropagation
- •Transformer architecture: encoders, decoders, self-attention
- •Multi-head attention mechanisms
- •Positional encoding and layer normalization
- •LLM training, inference, and scaling laws
- •Loss functions and optimization
- •Encoder-only vs decoder-only vs encoder-decoder models
Skills Tested
Example Question Topics
- What is the purpose of multi-head attention in transformers?
- How do encoder-only models differ from decoder-only models?
- Why do transformers use positional encoding?
Domain Priority Strategy
Focus your study time proportionally:
- 30% on Core ML (Domain 1) - This is the largest domain and foundation
- 24% on Software Dev (Domain 2) - Practical skills you'll use
- 22% on Experimentation (Domain 3) - Prompting and fine-tuning
- 14% on Data (Domain 4) - Easier concepts
- 10% on Trustworthy AI (Domain 5) - Free points if studied
Master transformer architecture first. Everything else builds on it.
Your 5-Week Study Plan
This schedule works for beginners with basic programming knowledge. Adjust based on your background.
Daily Study Commitment
Minimum effective dose: 1-1.5 hours per day, 5-6 days per week
- Weekdays: 45 min reading/videos + 15 min practice questions
- Weekends: 2 hours focused study
- Total: ~40-50 hours over 5 weeks
This is an entry-level exam. Consistent daily study beats weekend cramming.
The 12 Concepts That Appear on 80% of Questions
Don't try to learn everything. Master these first:
Must-Know Concepts
| Concept | Domain | What You MUST Know |
|---|---|---|
| Transformer Architecture | Core ML | Encoder, decoder, self-attention, multi-head attention, positional encoding |
| Attention Mechanism | Core ML | How attention weights are computed, why multi-head helps, Q/K/V purpose |
| Encoder vs Decoder | Core ML | Encoder-only (BERT), decoder-only (GPT), encoder-decoder (T5) - when to use each |
| Prompt Engineering | Experimentation | Zero-shot, few-shot, chain-of-thought - when each works best |
| LoRA Fine-Tuning | Experimentation | What LoRA is, why its memory efficient, when to use vs full fine-tuning |
| Evaluation Metrics | Experimentation | Perplexity, BLEU, ROUGE - what each measures and when to use |
| Tokenization | Data | BPE (GPT), WordPiece (BERT), SentencePiece - purpose and differences |
| Text Embeddings | Data | How embeddings capture meaning, why vectors enable similarity search |
| LangChain | Software Dev | Purpose, chains, agents, when to use for LLM orchestration |
| NVIDIA NIM | Software Dev | What it is, how to deploy models, basic configuration |
| Bias Detection | Trustworthy AI | Types of bias, how to detect, mitigation strategies |
| Hallucination | Trustworthy AI | What causes it, how to detect, RAG as solution |
Common Mistakes That Cause Failures
These are the top reasons candidates fail on their first attempt. Avoid them.
How to Study Each Domain Effectively
Domain 1: Core ML Knowledge (30%) - Your Foundation
This is the largest domain. Master it and you're 30% of the way there.
Key Concepts to Internalize:
- Transformer Flow: Input → Embedding + Positional Encoding → Attention → FFN → Output
- Attention Purpose: Allows model to focus on relevant parts of input sequence
- Multi-Head Benefit: Different heads learn different relationship types
- Encoder vs Decoder: Bidirectional understanding vs sequential generation
Core ML Gotchas
Common exam traps:
- Positional encoding is ADDED to embeddings, not concatenated
- Self-attention is different from cross-attention
- Layer normalization is used (not batch normalization)
- GPT is decoder-only; BERT is encoder-only
- T5 is encoder-decoder (not just encoder)
Domain 2: Software Development (24%)
This domain tests practical tool usage.
Tools to Know:
Key Tools Quick Reference
| Tool | Purpose | When to Use |
|---|---|---|
| LangChain | LLM orchestration | Building chains, agents, multi-step workflows |
| Hugging Face | Model repository | Loading pre-trained models, datasets |
| NVIDIA NIM | Model deployment | Production inference at scale |
| Triton Server | Inference serving | High-performance model serving |
| RAPIDS/cuDF | GPU data processing | Large dataset processing with GPU |
Domain 3: Experimentation (22%)
This domain tests prompting and fine-tuning knowledge.
Prompt Engineering Decision Tree:
Which Prompting Technique?
Use this decision tree:
- Zero-shot: Task is simple, model is capable, no examples needed
- Few-shot: Task needs examples, 2-5 examples fit in context
- Chain-of-thought: Reasoning required, step-by-step helps
- Fine-tuning: Many examples, consistent behavior needed, budget available
Domain 4 & 5: Data & Trustworthy AI (24%)
These are easier points. Know the basics.
Key Tokenization Facts:
- BPE (Byte Pair Encoding): Used by GPT models
- WordPiece: Used by BERT
- SentencePiece: Language-agnostic, used by T5
Trustworthy AI Basics:
- Bias exists in training data → appears in outputs
- Hallucination = confident wrong answers
- RAG reduces hallucination by grounding in documents
- Content filtering needed for public-facing apps

Exam Day: The Final 24 Hours
The Day Before
- Light review only: Skim notes on transformer architecture, key tools
- Prepare environment: Test webcam, clear desk, check ID
- Sleep 7-8 hours: Mental performance drops with less sleep
- No new material: Cramming causes confusion
Exam Morning
- Eat breakfast: Your brain needs fuel for 60 minutes of focus
- Log in 10 minutes early: Complete environment check calmly
- Have water nearby: Stay hydrated
- Deep breaths: Calm nerves before starting
During the Exam
Time Management:
- ~1.2 minutes per question
- Don't spend >2 minutes on any question
- Flag difficult questions, move on, return later
- Use remaining time to review flagged questions
Question Strategy:
- Read carefully - identify what concept is tested
- Eliminate wrong - usually 1-2 are obviously wrong
- Look for keywords: "BEST," "FIRST," "MOST likely"
- When stuck: Pick the most "NVIDIA-aligned" answer
- Review all before submitting
Answer Selection Tips
When two answers seem equally valid, prefer:
- NVIDIA tools over generic alternatives
- Practical approaches over theoretical
- Specific over vague
- Standard practices over edge cases
What to Do If You Fail
It happens. Here's your recovery plan:
- Wait for score report (24-48 hours)
- Identify weak domains from your results
- Wait 14 days (required retake period)
- Focus study on weak areas only
- Take 3 more practice exams targeting weak domains
- Retake - most pass on second attempt
Remember: The certification doesn't show attempt count. Pass is pass.
