Module 01 Knowledge Check
5 questions. Pass mark 4 out of 5. Answer every question before checking the answer key below, then retry after reading the feedback.
1. In CrewAI terms, a task is best understood as…
- A. An agent's personality
- B. A unit of work with a defined expected output
- C. A tool
- D. A model call
2. The strongest reason to use multiple agents rather than one is…
- A. It performs better by default
- B. Genuinely distinct roles need different tools, permissions, or context
- C. It is the framework's purpose
- D. It reduces cost
3. A Flow differs from a Crew mainly in that it…
- A. Uses more agents
- B. Gives explicit, deterministic control over execution order
- C. Is faster
- D. Needs no tools
4. Multi-agent systems most commonly disappoint because…
- A. Models are weak
- B. Coordination overhead and looping outweigh the benefit of specialisation
- C. Tools are limited
- D. Costs are fixed
5. Before building a crew you should first define…
- A. The agent personas
- B. The output you need and how you will judge whether it is acceptable
- C. The tools
- D. The model

Answer Key and Explanations
Check these only after attempting every question.
1. B - A unit of work with a defined expected output
Tasks carry the expected output; agents carry the capability. Confusing the two produces vague results.
2. B - Genuinely distinct roles need different tools, permissions, or context
More agents add coordination overhead and new failure modes. The separation must earn its cost.
3. B - Gives explicit, deterministic control over execution order
Flows are for when you want the sequence decided by you, not inferred at runtime.
4. B - Coordination overhead and looping outweigh the benefit of specialisation
Start with the simplest structure that works and add agents only when a real boundary appears.
5. B - The output you need and how you will judge whether it is acceptable
Without a defined acceptable output, no amount of agent design converges on anything.
Practical Check
Apply this module to your own work: complete the module activity for *CrewAI Concepts: Agents, Tasks, Crews, and Flows*, then write one sentence naming what your result shows and one naming what it does not.
Strong Answer Pattern
A strong answer names the task, the evidence used, the check performed, and the remaining limitation. It avoids "proved", "guaranteed", or "always" unless the evidence genuinely supports it.
