Judge the quality yourself

Sample question 1

Before sharing support transcripts with an outside vendor, a company must automatically find and remove names, addresses, and phone numbers. Which text analysis capability does this require?

  • a.Detecting and redacting personally identifiable information (PII)✓ correct
  • b.Summarizing the transcripts into shorter versions
  • c.Detecting which language each transcript is written in
  • d.Synthesizing speech from the transcripts
Why A: (A) Finding and removing private details like names, addresses, and phone numbers is PII detection and redaction. It's a specialized form of entity detection, used to meet privacy requirements. (B) summarization shortens text but doesn't strip out private data, (C) language detection only identifies the language, and (D) speech synthesis produces audio, which is unrelated.
Sample question 2

A company builds an assistant that first retrieves relevant sections from its internal expenses policy and adds them to the prompt, so the model answers from that policy instead of giving a generic reply. Which technique is this?

  • a.Tokenization
  • b.Speech synthesis
  • c.Positional encoding
  • d.Retrieval augmented generation (RAG)✓ correct
Why D: (D) Retrieving relevant documents and adding them to the prompt so the response is grounded in that information is retrieval augmented generation. (A) tokenization and (C) positional encoding are internal steps in how a model processes text, and (B) speech synthesis produces audio. None of them grounds a response in retrieved content.

What AI Is — and the Five Things It Does

The whole exam depends on one skill: hearing a real-world task and knowing which kind of AI it calls for. Before any Microsoft Foundry mechanics, we draw the map — what artificial intelligence actually is, and the five workload families you'll meet again and again. Every later chapter takes one of these families and shows how you build it. This chapter is the map, and we will return to it often.

Artificial intelligence is software that does things we normally associate with human intelligence. That means understanding what someone wrote or said, making sense of a picture, pulling facts out of a messy document, or producing brand-new content. For a fundamentals exam the goal isn't the mathematics underneath. The goal is a feel for the kinds of tasks AI can take on, and the vocabulary to name them.
Underneath almost every one of those capabilities sits machine learning. Rather than being programmed with explicit rules, a model is trained on large amounts of example data. Training continues until the model can make useful predictions about new input it has never seen. A vision model learns from many labelled images; a language model learns from vast quantities of text. You don't need the training details for this exam — just the idea that an AI capability is a trained model applied to fresh input.

Mental model

A useful way to remember the whole exam: think of AI as a set of senses plus a voice. It can see (computer vision), hear (speech), read and understand (natural language processing), pull the facts out of the clutter (information extraction), and speak and create (generative AI). Five abilities — that's the map.
THE FIVE AI WORKLOADS THE CUE → 1 Generative AI & agents Creates new content from a prompt; agents add tools to act. the task is to create or converse 2 Computer vision Interprets images, video, and live camera feeds. the input is a picture 3 Speech Speech-to-text in; text-to-speech out. audio is spoken in or out 4 Natural language processing Finds meaning in written text: sentiment, entities, summaries. the input is text 5 Information extraction Turns documents, forms, and media into structured data. messy files become tidy data
Figure 1.1 — The five AI workloads in one view. Each family is defined by what it takes in and what it produces. Listen for the right-hand cue in an exam scenario — the input or the goal usually names the workload for you.

Worked example

Walk a mixed scenario the way the exam wants you to — splitting one product into its workloads. A travel company builds a help line. A caller can ask a question out loud (that's speech — recognition). The call is transcribed for the record (speech again — speech-to-text). The transcript is scored for how happy the caller sounded (NLP — sentiment analysis). The assistant drafts a friendly reply to read back (generative AI). And a photo of the customer's paper ticket is used to pull out the booking reference (information extraction). One feature, four workloads — and naming each one is exactly the skill Domain 1 tests.

Excerpt ends here — the full chapter continues with the five workloads in depth, exam traps, and verified practice questions.
