The active-reading range uses 90–130 words per minute for technical material. Labs, troubleshooting, note-taking, spaced review, and prerequisite gaps add time; it is not a total preparation promise.

Assessment contract: 44 questions; 31 required to pass; 60 minutes.
Current status: Live. The official record showed no replacement or withdrawal notice when checked.
Study stance: Learn to select and govern an AI approach, not merely recite model names.

How to use this guide

For every concept, connect five things: business decision, data, model/approach, evaluation, and operating control. Draw the flow from input to output and identify where quality, bias, privacy, security, cost, or human oversight can fail.

About related items: A Related item: callout adds practical or architectural context. It is supporting knowledge, not a claim that its wording appears in the published objectives.

1. AI foundations

AI is the broad pursuit of systems performing tasks associated with intelligence. Machine learning learns patterns from data; deep learning uses multilayer neural networks; generative AI produces new content; predictive AI estimates labels or values. Symbolic systems use explicit rules, while foundation models learn broadly reusable representations from large-scale training.

Structured data has a defined schema, unstructured data includes free text/images/audio, and semi-structured data carries tags or keys without a fixed relational form. Data type influences preparation, model family, storage, evaluation, and governance. Foundation models can be adapted across tasks; an LLM is a language-oriented foundation model; an agent combines a model with goals, tools, state/memory, and control logic.

Transformers use attention to relate tokens across context. They enable parallel training and modern language capabilities, but do not guarantee truth, current knowledge, reasoning, privacy, or authorization. Capabilities and limitations must be tested for the actual task.

2. Machine learning and deep learning

Supervised learning uses labeled examples for classification or regression. Unsupervised learning finds structure such as clusters or lower-dimensional representations. Reinforcement learning learns behavior from actions, states, and reward. Common classical methods include linear/logistic models, trees/ensembles, nearest-neighbor, clustering, and anomaly detection.

A lifecycle moves from problem definition and data preparation through training, validation/testing, deployment, monitoring, and revision. Split data so evaluation is not performed on examples used to fit the model. Classification metrics include precision, recall, F1, and ROC-related measures; regression metrics quantify errors. Choose metrics from business error costs, not convenience.

Underfitting means the model cannot capture relevant structure; overfitting means it learns training detail that does not generalize. Use suitable data, regularization, validation, feature/model choices, and monitoring. Neural networks learn layered representations and are strong for high-dimensional data, but may demand more data/compute and be harder to interpret than classical approaches.

Related item: High accuracy can conceal failure on a rare but costly class. Always inspect class balance, false-positive/false-negative consequences, and performance by relevant population.

3. Generative and applied AI

LLMs map text to tokens and predict subsequent tokens from context. Prompting supplies instructions, context, examples, constraints, and output format. Temperature and related decoding settings affect variability; they do not make a model know facts it lacks.

Embeddings map content to vectors so semantic similarity can be measured. A vector database stores/indexes embeddings plus metadata. RAG retrieves relevant authorized content and places it in model context; it can improve grounding and freshness, but poor retrieval, stale sources, malicious content, or ignored evidence still produce bad answers.

Fine-tuning changes model behavior through additional training; RAG supplies external knowledge at inference. Use prompting first for instructions, RAG for changing/private evidence, and fine-tuning when repeated behavior/style/task performance justifies training and governance cost. Agents add tool use and iterative decisions; constrain permissions, validate tool inputs/outputs, cap loops/cost, and retain auditable traces.

4. Responsible AI, ethics, security, and governance

Ethics asks what ought to be built and how impacts are distributed. Responsible AI turns principles—fairness, transparency/explainability, robustness, privacy, accountability, and human oversight—into lifecycle practices. Governance assigns decisions, owners, evidence, approvals, inventory, risk tiers, monitoring, and incident/change processes.

Security covers training/data poisoning, prompt injection, sensitive-data exposure, model theft, unsafe output, supply-chain risk, insecure tools, and denial/cost abuse. Apply least privilege, data classification, isolation, input/output controls, grounded authorization, adversarial testing, monitoring, and response. A content filter alone is not a complete control system.

Related item: governance for AI agents. IBM's October 14, 2026 watsonx.governance announcement describes asset discovery for agents, tools, MCP servers and knowledge sources, rule checks and developer-facing risk findings. This is one vendor's current example, not a universal AI governance control or a C1000-206 objective. Inventory does not establish safety; evaluate permissions, data lineage, behavior and human accountability. IBM announcement.

5. Use cases and integration

Start with outcome, user, workflow, error cost, latency, volume, data rights, explainability, integration, and fallback. Traditional ML fits stable prediction/classification from measurable features. GenAI fits synthesis and unstructured interaction. Rules may be best when policy is explicit and deterministic.

Integration patterns include batch scoring, synchronous APIs, event-driven processing, embedded assistants, human review queues, and tool-using agents. Monitor quality, drift, latency, availability, safety, usage, cost, and business outcomes. Map applicable regulation and policy by jurisdiction, data, sector, and decision impact; escalate legal interpretation to qualified owners.

Integrated practice scenarios

1. Service routing: Compare rules and supervised classification, define labels/metrics, protect customer data, and design human escalation.
2. Policy assistant: Design permission-aware RAG with citations, retrieval evaluation, prompt-injection defenses, abstention, and freshness ownership.
3. Demand forecast: Define time-aware validation, baseline metrics, drift monitoring, and an operational fallback.

Hands-on labs

1. Classify ten business requests as rules, predictive ML, GenAI, or hybrid and justify each.
2. Build a tiny labeled classification example and calculate precision, recall, and F1 from a confusion matrix.
3. Demonstrate overfitting by comparing train and held-out performance as model complexity grows.
4. Tokenize sample prompts conceptually and test how clearer constraints change output quality.
5. Create a small embedding/retrieval experiment and inspect false matches and missing evidence.
6. Threat-model a RAG assistant for prompt injection, data leakage, and excessive permissions.
7. Draft a model card/control record with purpose, data, metrics, limitations, owner, and monitoring.
8. Build an AI use-case decision sheet including value, risk, integration, fallback, and acceptance tests.
