Question 1: What is the primary function of a Large Language Model (LLM)?
- Database management
- Hardware manufacturing
- Network security
- Natural language processing
Answer: D. Natural language processing
Explanation: An LLM is a neural network specifically trained on vast amounts of text data to perform natural language processing tasks, such as generating human-like text.
Question 2: In the context of LLMs, what is a 'token'?
- A small chunk of text
- A hardware component
- A security password
- A user account ID
Answer: A. A small chunk of text
Explanation: A token is a small unit of text that an LLM processes, which can be a whole word, a part of a word, or even a single punctuation mark.
Question 3: What does the 'context window' of an LLM determine?
- The physical size of the server
- The speed of the internet connection
- The model's training date
- The number of tokens processed at once
Answer: D. The number of tokens processed at once
Explanation: The context window defines the maximum number of tokens an LLM can consider simultaneously when it is predicting the next token in a sequence.
Question 4: What is the 'knowledge cutoff' of an LLM?
- The date training data stopped
- The end of the model's life
- The limit on user questions
- The time the server shuts down
Answer: A. The date training data stopped
Explanation: The knowledge cutoff is the specific date when an LLM stopped learning from new data, meaning it lacks knowledge of events occurring after that time.
Question 5: Which term describes the process of generating text by predicting the next token?
- Pre-training
- Inference
- Fine-tuning
- Embedding
Answer: B. Inference
Explanation: Inference is the operational phase where a generative LLM produces text by calculating the most likely next token based on the input sequence provided.
Question 6: What is the goal of 'Prompt Engineering'?
- Deleting old training data
- Writing new model code
- Repairing server hardware
- Designing optimized input prompts
Answer: D. Designing optimized input prompts
Explanation: Prompt engineering is the practice of carefully designing and refining input prompts to guide an LLM toward producing more accurate or desired outputs.
Question 7: What do 'vector embeddings' represent in an LLM?
- Model training dates
- Hardware power usage
- Numerical semantic meaning
- User login credentials
Answer: C. Numerical semantic meaning
Explanation: Vector embeddings are compact numerical representations that capture the semantic meaning or context of words and sentences within the model's space.
Question 8: What is 'few-shot learning' in LLM usage?
- Limiting the model to few answers
- Using a small amount of memory
- Providing examples to improve performance
- Training on only a few words
Answer: C. Providing examples to improve performance
Explanation: Few-shot learning involves providing an LLM with a small number of examples of a task to help the model better understand and perform that specific task.
Question 9: What does 'Chain-of-Thought' prompting encourage an LLM to do?
- Ignore the user's prompt
- Use more computing power
- Generate intermediate reasoning steps
- Skip the final answer
Answer: C. Generate intermediate reasoning steps
Explanation: Chain-of-Thought prompting improves reasoning by instructing the model to generate intermediate logical steps before arriving at the final answer to a problem.
Question 10: What is a 'hallucination' in the context of AI?
- An unauthorized user access
- A system crash
- A slow response time
- Making up facts not grounded in data
Answer: D. Making up facts not grounded in data
Explanation: Hallucination occurs when an AI generates information that is factually incorrect or not grounded in the provided data, essentially making up details.
