  "title": "The MCPA Blueprint Is a Study Budget, Not a Checklist",
  "questions": [
    {
      "stage": "pre",
      "question": "What does a domain's weight in the MCPA blueprint most directly tell a candidate?",
      "options": [
        "The order in which the five domains appear in the official guide",
        "The share of exam questions drawn from that domain, on average",
        "The minimum score a candidate must reach in that domain alone",
        "The number of official training hours required before attempting it"
      ],
      "correct": 1,
      "explanation": "A domain's published weight is its share of the blueprint, the proportion of exam content the domain represents; it does not set a reading order, a required hour count, or a per-domain minimum score."
    },
    {
      "stage": "check",
      "question": "Which pair of domains carries the largest combined share of the MCPA blueprint?",
      "options": [
        "MCP Fundamentals and Architecture and Components, the two foundational domains",
        "Architecture and Components and Use Cases and Ecosystem, the two mid-weight domains",
        "Interactions and Execution and Security and Governance, the two heaviest domains",
        "Use Cases and Ecosystem and MCP Fundamentals, the two adoption-facing domains"
      ],
      "correct": 2,
      "explanation": "Interactions and Execution is weighted 26 percent and Security and Governance is weighted 24 percent, together half the blueprint, which is why they deserve the largest share of study hours."
    },
    {
      "stage": "check",
      "question": "The MCPA certification page and the Linux Foundation's own launch press release disagree about one exam fact. Which fact is it, and which source does this curriculum follow?",
      "options": [
        "The included retake count",
        "The credential validity period",
        "The exam fee",
        "The exam duration"
      ],
      "correct": 3,
      "explanation": "The certification page states a 90 minute duration while the press release states 120 minutes; this curriculum follows the certification page as the exam-specific source and records the conflict rather than silently choosing a number."
    },
    {
      "stage": "check",
      "question": "A practice question claims a client must call initialize before a 2026-07-28 server will accept any other request. How should a prepared candidate read that claim?",
      "options": [
        "A legacy-era protocol distractor",
        "True only for older MCP servers",
        "A detail specific to stdio only",
        "A true, still current requirement"
      ],
      "correct": 0,
      "explanation": "The 2026-07-28 revision removed the initialize handshake and protocol sessions entirely, so every request now carries its own protocol version and capabilities in its metadata instead of relying on a prior handshake."
    },
    {
      "stage": "post",
      "question": "A candidate scores 100 percent in MCP Fundamentals, weighted 16 percent, and 0 percent everywhere else. Why is a weighted readiness estimate more useful here than a plain five-way average?",
      "options": [
        "It rounds every domain score upward so the candidate always looks prepared",
        "It shows readiness near 16 percent instead of a misleading 20 percent average",
        "It replaces the five domains with a single combined pass or fail flag",
        "It discards the weakest domain scores before computing any final result"
      ],
      "correct": 1,
      "explanation": "A plain average shows 20 percent because one of five domains is perfect, but a weighted estimate reflects that the mastered domain is only 16 percent of the exam, which is a more honest picture of overall readiness."
    },
    {
      "stage": "post",
      "question": "A few lessons in the 34-lesson route, such as JSON-RPC and Meta, are tagged with two domains instead of one. What does that reflect about the route?",
      "options": [
        "A sign those lessons are optional to skip",
        "A sign those lessons get double the study time",
        "A concept tested from two domains at once",
        "A numbering error the curriculum needs to fix"
      ],
      "correct": 2,
      "explanation": "A lesson can sit at a genuine intersection, such as a message envelope that is both a core concept and a piece of the architecture, so the route tags it under both domains rather than forcing one arbitrary choice."
