Domain 1: AI Fundamentals and Literacy
1. A business leader must choose between a rules-based system and a machine learning model for approving expense claims. Which factor most strongly favours machine learning?
Answer and explanation
Answer: D. Machine learning earns its complexity when patterns are too intricate to enumerate and shift over time, and when labelled history exists to learn from. Few stable rules are cheaper and more transparent as explicit logic. A requirement that every decision map to a documented rule favours a rules engine for auditability. Without historical data there is nothing for a supervised model to learn.
2. A business problem can be solved by a set of clearly defined rules that rarely change. Which approach should be selected?
Answer and explanation
Answer: A. Deterministic rules that rarely change are solved most cheaply and reliably by rule-based automation, which is also easier to audit. A trained model introduces data, drift, and explainability burdens for logic that is already known. A foundation model adds nondeterminism to a problem with one correct answer. An agent adds planning where no planning is needed.
3. An executive asks why a generative AI pilot produced confident but factually wrong answers about company policy. Which explanation is correct?
Answer and explanation
Answer: C. Foundation models generate fluent text from general training data, so questions about proprietary internal content produce confident fabrication unless the system retrieves and grounds answers in the actual documents. Memory allocation is an infrastructure parameter unrelated to factual accuracy. Encryption of training data does not cause hallucination. Bandwidth affects delivery speed, not correctness.
4. An executive asks how generative AI differs from the predictive machine learning the company already uses. Which distinction is most accurate?
Answer and explanation
Answer: B. The essential difference is the output: a predictive model returns an estimate such as a score or class, whereas a generative model produces novel content. Hardware is not the distinguishing factor. Both approaches depend on data. The two solve different problems and coexist rather than one replacing the other.
5. A business leader is told a proposed use case needs "unstructured data". Which example qualifies?
Answer and explanation
Answer: D. Unstructured data lacks a predefined schema and includes free text, audio, images, and video. A sales table, a relational SKU database, and a headcount spreadsheet are all structured, with defined fields and types.
6. Which statement best describes why data quality matters more than model choice for most business AI initiatives?
Answer and explanation
Answer: B. A model learns the patterns present in its data, so incomplete, inconsistent, or unrepresentative inputs cap achievable performance regardless of algorithm. Models can be swapped readily. Licensing cost is unrelated to data quality. Poor data affects correctness and fairness, not merely how fast training runs.
7. A team proposes AI for a task with a small number of stable, legally mandated rules that must be applied identically every time. What should the strategist recommend?
Answer and explanation
Answer: C. Where rules are few, stable, and legally mandated, explicit logic gives exact repeatability and a clear audit trail that a probabilistic model cannot match. A generative model introduces variability into a task that must not vary. A predictive model trained on past decisions can reproduce past errors. Letting a model override mandated rules creates legal exposure.
8. An organization must decide whether to build an AI capability in house, buy a vendor product, or partner. Which combination of factors should be weighed? (Select TWO.)
Answer and explanation
Answer: D, E. A build-buy-partner decision turns on whether the organization has the capability and time to build, and on what the budget and regulatory obligations permit. The count of models a vendor offers says nothing about fit. Language preference is a detail below this decision. Vendor headcount is not a proxy for suitability.
9. What does it mean that a foundation model is "stateless" between requests?
Answer and explanation
Answer: C. Each request is independent, so an application must resend whatever prior context the model should consider. Statelessness does not prevent fine-tuning, which alters weights rather than session state. Retaining conversations for training is a separate policy matter and is not what statelessness means. Inference still requires infrastructure, whether managed or not.
10. A vendor claims their model achieves 96 percent accuracy on a task where 95 percent of cases belong to one class. How should a strategist interpret this?
Answer and explanation
Answer: D. On a 95 percent imbalanced dataset a model that always predicts the majority class scores 95 percent, so 96 percent may represent almost no useful capability, and minority-class metrics are what reveal the truth. The headline figure alone does not demonstrate effectiveness. It says nothing about dataset size. No single accuracy threshold indicates readiness.
11. Which describes the relationship between artificial intelligence, machine learning, and deep learning?
Answer and explanation
Answer: D. AI is the broad field, machine learning is the subset that learns from data, and deep learning is the subset of machine learning using multi-layer neural networks. The fields are nested rather than independent. The hierarchy is not inverted, and machine learning includes many non-deep methods.
12. A proposed use case has no historical examples of the outcome to be predicted, and the outcome cannot be reliably labelled. What should a strategist conclude?
Answer and explanation
Answer: D. Supervised learning requires labelled examples, so without them the prerequisite investment is data collection or a reframing of the problem, not model selection. Model size cannot substitute for absent ground truth. Generative AI addresses content production rather than a missing-label problem. Labelling after deployment means the deployed system was never validated.
13. A business wants to estimate next quarter's demand for each product line from several years of sales history. Which class of problem is this?
Answer and explanation
Answer: C. Predicting a future numeric value from historical time-ordered observations is forecasting. Clustering groups records without a target. Anomaly detection identifies unusual observations rather than projecting future values. Content generation produces new material rather than an estimate.
14. Which limitation should a strategist expect from a general-purpose language model performing precise multi-step arithmetic?
Answer and explanation
Answer: B. Language models generate text probabilistically and can make arithmetic errors while sounding certain, so exact computation belongs in code or a calculator the model calls. Models attempt numerical questions rather than refusing them. They are not more reliable than a deterministic spreadsheet for arithmetic. They do process numbers, just not always correctly.
15. An executive asks what "training" costs compared with "inference" for a business using a managed foundation model. Which statement is correct?
Answer and explanation
Answer: C. With a managed foundation model the provider absorbs base model training, and the customer's recurring cost is inference, with fine-tuning or continued pre-training as optional additional spend. Base training is not re-charged per request. Inference is the principal ongoing charge rather than free. The two are structurally different costs and not equal per request.
16. Which use case is best served by computer vision rather than natural language processing?
Answer and explanation
Answer: B. Identifying defects from images is a computer vision task. Sentiment classification, summarization, and topic routing all operate on text and belong to natural language processing.
17. What does a model's confidence score represent, and how should a business treat it?
Answer and explanation
Answer: C. Confidence scores are useful for routing and thresholds but are not automatically well calibrated, so they must be validated against observed outcomes before being read as probabilities. They do not guarantee correctness. They say nothing about training volume or business value.
18. Which describes an AI agent as distinct from a single model call?
Answer and explanation
Answer: D. An agent adds planning and tool use so the system can take actions rather than only produce text in one response. Parameter count, hardware, and fine-tuning describe the model rather than the agentic pattern around it.
19. What is MLOps, in business terms?
Answer and explanation
Answer: D. MLOps is the discipline of operationalising models so they can be deployed, monitored, retrained, and governed reliably, analogous to DevOps for software. It is a practice rather than a role, an algorithm, or a pricing model.
20. Which statement about a foundation model's knowledge is accurate?
Answer and explanation
Answer: B. A model's parametric knowledge is fixed at training, so recent events and proprietary content must be supplied through retrieval or context. Models are not continuously updated in place. Training data is extensive but not exhaustive. Models do not learn from individual conversations.
21. A business wants to recommend products to customers based on the behaviour of similar customers. Which approach describes this?
Answer and explanation
Answer: C. Collaborative filtering infers preferences from patterns across similar users, which is the standard recommendation approach. Anomaly detection finds unusual records. Forecasting projects values over time. Optical character recognition extracts text from images.
22. Which factor most determines whether a generative AI output can be used without human review?
Answer and explanation
Answer: A. The decision rests on how much harm an error causes and how reliably the system performs on that task, which is a risk judgement rather than a technical one. Response speed, model size, and output modality do not determine acceptable risk.
23. Which describes the practical difference between interpretability and explainability?
Answer and explanation
Answer: D. An inherently interpretable model such as a small decision tree can be read directly, while explainability techniques produce post-hoc accounts of individual predictions from models that are not themselves transparent. The terms are related but distinct. Neither is restricted to generative models, and explanation techniques do not require source code.
24. Which capability distinguishes an AI agent from a single-response AI tool?
Answer and explanation
Answer: A. Planning and tool use to pursue a goal is what makes a system agentic. Context window size, training data, and speed all describe the underlying model rather than the agentic pattern.
25. Why do deployed AI solutions require ongoing monitoring?
Answer and explanation
Answer: B. Drift between production data and training data degrades performance over time, which is why monitoring is continuous rather than a launch activity. Compute consumption does not grow with age. Licences and training data retention are unrelated to the need for monitoring.
26. Employees are using unapproved AI tools with company data. Which governance measure addresses this risk?
Answer and explanation
Answer: A. A published classification gives employees a sanctioned path and makes the boundary clear, which is what reduces shadow AI. A blanket prohibition drives the practice underground. Ignoring it leaves data exposed. Individual assessment produces inconsistent judgements about risk.
27. A business user reports that a generative AI assistant loses track of earlier parts of a long document. Which constraint explains this?
Answer and explanation
Answer: C. A context window bounds how much the model can attend to in a single request, which is why long documents lose earlier content. Fine-tuning affects behaviour rather than working memory. Temperature affects variability. Model version does not remove the window.
28. Which adaptation technique allows a generative AI system to answer from company documents that change weekly?
Answer and explanation
Answer: C. Retrieval supplies current documents at query time, which suits content that changes frequently and allows the source to be cited. Weekly fine-tuning or pre-training is expensive and lags the change. Temperature affects variability rather than knowledge.
29. Which statement distinguishes artificial intelligence from machine learning?
Answer and explanation
Answer: B. Machine learning is a subset of artificial intelligence characterised by learning from data. The relationship is not reversed, the terms are not interchangeable, and machine learning covers far more than generative systems.
30. What does it mean for a model to generalize?
Answer and explanation
Answer: D. Generalization is performance on unseen data. Identical output describes a constant function. Universal applicability and zero training data are not what the term means.
31. What is a parameter in the context of a machine learning model?
Answer and explanation
Answer: D. Parameters are learned during training. Settings configured before training are hyperparameters. Inputs at prediction time are features. Accuracy is an evaluation metric.
32. Which statement describes training data?
Answer and explanation
Answer: A. Training data is the input examples the model learns from. Output, configuration, and infrastructure are separate elements of the training process.
33. What does a confidence score accompanying a model's prediction indicate?
Answer and explanation
Answer: D. A confidence score is an estimated likelihood that is often poorly calibrated and should not be read as a guarantee. It does not report training data proportions or timing.
34. A business problem requires predicting which of three categories a record belongs to. Which solution type applies?
Answer and explanation
Answer: B. Classification predicts a category. Regression predicts a continuous value. Clustering groups records without predefined categories. Anomaly detection flags unusual records.
35. A business problem requires predicting a numeric value such as expected demand. Which solution type applies?
Answer and explanation
Answer: B. Regression predicts a continuous numeric value. Classification predicts categories. Clustering groups records. Recommendation predicts preference.
36. An organization must decide whether to adopt an autonomous AI agent for a process. Which consideration is most important?
Answer and explanation
Answer: A. Autonomy is justified by whether its errors are tolerable and what oversight exists. Model recency, tool count, and speed do not address the risk of autonomous action.
37. A business process must be evaluated for AI suitability. Which characteristic indicates a poor fit?
Answer and explanation
Answer: B. An unmeetable explainability requirement is a genuine blocker. High volume, historical data, and manual effort all favour AI adoption.
38. What does a foundation model's pre-training provide?
Answer and explanation
Answer: D. Pre-training builds broad general capability that fine-tuning or prompting then directs. Task specificity, retrieval indexes, and prompts all come afterwards.
39. Which adaptation technique changes a foundation model's weights?
Answer and explanation
Answer: C. Fine-tuning updates weights. Prompt engineering, retrieval, and temperature all change behaviour at inference without altering the model.
40. Why does a generative AI system sometimes produce different answers to the same question?
Answer and explanation
Answer: B. Sampling during generation produces variation. Models do not retrain between requests, do not vary retrieval arbitrarily, and do not change parameters at inference.
41. Which characteristic indicates that a business problem suits a generative AI solution rather than a traditional model?
Answer and explanation
Answer: A. Varied content generation suits generative AI. Labelled examples favour traditional supervised learning, and explainability and exact repeatability both work against generative systems.
42. An organization must decide whether a process should be automated with an AI agent or kept under human control. Which consideration is decisive?
Answer and explanation
Answer: B. Detectability and reversibility of an error determine whether autonomy is acceptable. Speed, tool count, and frequency describe the opportunity rather than the risk.
43. Which AI solution type predicts a category from labelled historical examples?
Answer and explanation
Answer: B. Supervised classification learns categories from labelled examples. Clustering groups without labels, generative modelling produces content, and reinforcement learning optimises against a reward.
44. Why does a generative AI system require different governance from a traditional predictive model?
Answer and explanation
Answer: A. Open-ended output means governance evaluates content rather than a bounded outcome set. Infrastructure, data volume, and speed do not drive the governance difference.
45. Which concept describes supplying a generative AI system with an organization's own documents at query time?
Answer and explanation
Answer: C. Retrieval supplies documents at query time without changing the model. Fine-tuning and continued pre-training modify weights, and distillation transfers behaviour to a smaller model.
