AWS · AIF-C01 · AI Practitioner
More than half this exam is generative AI. Not one question asks you to write code.
AIF-C01 is foundational. It tests whether you can pick the right AI approach for a business problem, explain the difference between the technologies, and know where the risks sit — not whether you can build any of it. AWS states that developing models, tuning hyperparameters, and building pipelines are out of scope for this candidate.
- Questions weighted to the official domain split, so a mock matches the real mix
- Every item tagged to the domain and task statement it tests
- Readiness shown against 700, not as an invented percentage
Free practice across all five domains. No card required.

What the exam won't ask
AWS is unusually clear about what this exam isn't
Most certification anxiety comes from not knowing where the ceiling is. AWS removes that guesswork by publishing the job tasks a target candidate is not expected to perform.
Out of scope: developing or coding models and algorithms, data and feature engineering, hyperparameter tuning and model optimisation, building and deploying pipelines or infrastructure, mathematical and statistical analysis of models, implementing security and compliance protocols, and developing governance frameworks.
Read that list twice if you've been putting this exam off. You are expected to know what those things are and when they apply. You are not expected to do any of them.
What AWS does expect: up to six months of exposure to AI and ML on AWS, and familiarity with the core services, the shared responsibility model, IAM, and how AWS pricing works.
How it's scored
700 to pass, and you don't need 700 in every domain
Your result is a scaled score from 100 to 1,000, and 700 passes. Scaled means it isn't a percentage — how many questions you need right depends on the difficulty of the form you're given, which is why nobody can honestly tell you a target percentage.
The part that most study advice gets wrong: AWS uses a compensatory scoring model. You don't need to reach a passing standard in each domain. You need to pass the exam overall. A weak domain can be carried by a strong one, and plenty of advice telling you to hit 70% in every section is describing a rule that doesn't exist here.
Of the questions you see, 50 count towards your score and 15 don't. The unscored ones aren't marked, so there's no way to spot them and no reason to try.
There's no penalty for a wrong answer, and an unanswered question is scored as wrong. Never leave one blank.

700
Your scaled score lands somewhere around670–730Could go either way
Now change nothing except which form you were given
Same answers. Harder form, higher scaled score — that's what scaling is for. It's also why nobody can tell you the percentage you need.
Positions here are illustrative. AWS publishes the 100–1,000 scale and the 700 pass mark, but not the conversion from raw answers — which is the point. When a number can't be known exactly, a range is the honest way to report it.
Question types
Two of these you've seen before. Three you probably haven't.
Multiple choice
One correct answer, three distractors. The familiar one.
Multiple response
Two or more correct out of five or more options. Select every correct response to get the mark.
Ordering
Put 3–6 responses into the correct sequence using dropdowns. Sometimes you use every option, sometimes only some; the question says how many. All or nothing.
Matching
Pair responses against 3–6 prompts using dropdowns. Responses may be used once, several times, or not at all. Every pair must be right.
Case study
One scenario, two or more questions. Each is scored separately, so a wrong answer costs you only that question.
Only case study is forgiving, and only because it's several questions. On the rest, the one option you're unsure about decides the whole mark.
The loop
Practice, sit, review, repeat
Step 1 is free. Steps 2 to 4 need a subscription.

MediumA company wants its internal support assistant to answer questions using its own product documentation, which changes weekly. The team has no machine learning engineers and wants to avoid retraining anything.
Which approach should they use?
Retrieval Augmented Generation, with the documentation indexed in a vector store.
Fine-tune a foundation model on the documentation and repeat weekly.
Continued pre-training on the documentation corpus.
Increase the model's context window and paste the documentation into every prompt.
RAG grounds a foundation model's responses in an external source that can be updated independently of the model. Fine-tuning, continued pre-training, and stuffing the corpus into the context window each solve a different problem. Domain: Applications of Foundation Models.

What you get back
Not a prediction. A distance from the line.
Your readiness is a range, because it's an inference from the questions you've answered rather than a result you've earned. For a certification the outcome is binary, so the only question that matters is whether the whole range sits above 700.
While it straddles the line, you're a coin flip, and we'll say so.

Domains
What AIF-C01 actually covers
AWS publishes a weighted content outline. Our mocks follow those weights, so a domain worth a quarter of the exam gets a quarter of the questions.
| Domain | Weight |
|---|---|
| Fundamentals of AI and ML | 20% |
| Fundamentals of GenAI | 24% |
| Applications of Foundation Models | 28% |
| Guidelines for Responsible AI | 14% |
| Security, Compliance, and Governance for AI Solutions | 14% |
AWS publishes these as exact figures rather than ranges, and they apply to scored content. Last checked against the exam guide on 15 September 2026.
Domains 2 and 3 together are 52% of the scored exam. If you only have time for half the syllabus, generative AI and foundation models are the half.
Domain 3 is the largest and the most applied — prompt engineering, RAG, fine-tuning, model selection, evaluation. It's where the exam stops asking what things are and starts asking which one you'd choose.
The two 14% domains are the ones people skip, and they shouldn't. Between them they're 28% of the paper, they're the most memorisable material on it, and the questions tend to be unambiguous in a way the Domain 3 questions aren't.
