A) Sharing your prompts on social media B) A vulnerability where the model reveals its internal system instructions to the user C) The AI running out of memory during a long prompt D) Using too many emojis in a prompt Correct Answer: B) A vulnerability where the model reveals its internal system instructions to the user 4. What is a "System Prompt" (or System Message)? A) The error message shown when the server is down B) High-level instructions that define the AI’s persona, boundaries, and tone C) The final answer given by the AI D) A prompt written by the AI for another AI Correct Answer: B) High-level instructions that define the AI’s persona, boundaries, and tone 5. Which element is considered the most critical "Context" in a professional 2026 prompt? A) The current weather B) Background information or constraints relevant to the specific task C) The font size of the prompt D) The user's location (unless relevant to the task) Correct Answer: B) Background information or constraints relevant to the specific task 6. What does "Temperature" control in an LLM configuration? A) The physical heat of the server B) The randomness and creativity of the output C) The speed of text generation D) The number of languages supported Correct Answer: B) The randomness and creativity of the output 7. "Zero-shot" prompting means: A) The model has zero chance of answering correctly B) Asking the model to perform a task without any prior examples C) Using a prompt with zero words D) Training the model from scratch Correct Answer: B) Asking the model to perform a task without any prior examples 8. What is the purpose of "Delimiters" (e.g., triple quotes, XML tags) in a prompt? A) To make the prompt look more artistic B) To clearly separate different sections of the prompt (instructions, data, examples) C) To increase the token count D) To confuse the AI Correct Answer: B) To clearly separate different sections of the prompt (instructions, data, examples) 9. In 2026, "Iterative Prompting" is described as: A) Writing one prompt and never changing it B) The process of refining a prompt based on previous outputs to get better results C) Copying prompts from a database D) Letting the AI write the entire prompt Correct Answer: B) The process of refining a prompt based on previous outputs to get better results 10. What is "Role Prompting"? A) Asking the AI to act as a specific persona (e.g., "Act as a Senior Data Scientist") B) Changing the password of the AI system C) Listing the names of the developers D) Using the AI to find an actor for a movie Correct Answer: A) Asking the AI to act as a specific persona (e.g., "Act as a Senior Data Scientist") 11. Which term describes the maximum amount of text an AI can "remember" or process in one go? A) Memory Card B) Context Window C) Logic Gate D) Data Stream Correct Answer: B) Context Window 12. A) Math problems "Negative Prompting" is most commonly used in: B) Image generation to specify what NOT to include in the picture C) Translating languages D) Fixing code errors Correct Answer: B) Image generation to specify what NOT to include in the picture 13. What does "Persona Adoption" help achieve in prompt engineering? A) Faster response times B) More consistent tone and specialized expertise in the response C) Lower costs per token D) Better internet connection Correct Answer: B) More consistent tone and specialized expertise in the response 14. Which technique involves breaking a complex task into several smaller, manageable prompts?

In 2027, "Self-Consistency" prompting is used to: A) Make the AI agree with the user's opinion B) Generate multiple reasoning paths and select the most common answer C) Keep the AI's memory forever D) Reduce the size of the model Correct Answer: B) Generate multiple reasoning paths and select the most common answer 16. What is "Prompt Injection"? A) Adding more RAM to the server B) An attack where a user bypasses filters to make the AI perform unauthorized actions C) Translating a prompt into another language D) Sending a prompt via email Correct Answer: B) An attack where a user bypasses filters to make the AI perform unauthorized actions 17. What is the benefit of "Few-shot" over "Zero-shot"? A) It is always cheaper B) It provides patterns and style guides for the model to follow C) It makes the model work without electricity D) It uses fewer tokens Correct Answer: B) It provides patterns and style guides for the model to follow
