AWS AI Practitioner (AIF-C01): 10 Free Practice Questions with Explanations

A
AICertReady Editorial
Reviewed by a certified practitioner

Sitting AIF-C01 soon? These free sample questions mirror the difficulty and style of the live exam across all five domains. Work through them untimed, read every explanation, and see where you stand.

Sample question 1 — Generative AI Fundamentals

A retail company wants an LLM to answer questions using its internal product manuals without retraining the model. Which approach is MOST cost-effective?

AFine-tune the foundation model on all manuals
BRetrieval-Augmented Generation (RAG) over a vector store
CTrain a new foundation model from scratch
DIncrease the model temperature
Why: RAG retrieves relevant passages at query time and grounds the model's answer in them — no retraining required, which makes it far cheaper than fine-tuning or pre-training for knowledge-lookup use cases.

Sample question 2 — AI Security

A user crafts input that makes a chatbot ignore its system instructions and reveal internal data. This attack is known as:

AModel inversion
BPrompt injection
CData poisoning
DMembership inference
Why: Prompt injection manipulates an LLM through adversarial input to override its instructions. Guardrails, input filtering and privilege separation are standard mitigations.
