Correct answer: The prompt has exceeded the model's context window limit.

Large Language Models have a fixed 'context window' (measured in tokens) which represents the maximum amount of text they can process in a single interaction. When a conversation or document exceeds this limit, the model employs a sliding window approach, effectively 'forgetting' the earliest tokens to make room for new ones. This results in the loss of initial instructions or early document context. flowchart LR A[User Prompt + Long Doc] --> B{Exceeds Context Window?} B -- Yes --> C[Truncates Early Tokens] B -- No --> D[Processes Full Context] C --> E[Loss of Initial Instructions] D --> F[Accurate Output]

Correct answer: True

GPT stands for Generative Pre-trained Transformer. The 'Pre-trained' aspect is highly significant because it means the model has already ingested massive datasets to understand the statistical structure of human language. This foundational knowledge allows it to perform a wide variety of tasks out-of-the-box without needing to be trained from scratch for every new application.

Correct answer: The model functions by predicting the statistically most probable next token, prioritizing linguistic coherence over factual accuracy.

At their core, Large Language Models (LLMs) are complex probabilistic engines based on neural network architectures (specifically Transformers). They generate text by predicting the next most likely token (word or sub-word) based on the preceding context. Because they optimize for statistical probability and linguistic coherence rather than querying a factual database, they can easily piece together a sequence of tokens that looks completely legitimate (like a legal citation) but is entirely fabricated—a phenomenon known as hallucination.

Correct answer: It violates Data Privacy regulations (e.g., HIPAA); the mitigation is to implement an automated PII sanitization layer before data reaches the public model.

Pasting Personally Identifiable Information (PII) or Protected Health Information (PHI) into a public LLM instance is a severe violation of data privacy frameworks like HIPAA or GDPR, as public models may use input data for future training. The optimal mitigation strategy, if a public model must be used, is to implement a sanitization layer that redacts or anonymizes all sensitive data before the prompt is sent to the LLM. sequenceDiagram participant User participant Sanitizer participant Public LLM User->>Sanitizer: Prompt with PHI/PII Sanitizer->>Public LLM: Anonymized Prompt Public LLM-->>Sanitizer: Summarized Data Sanitizer-->>User: Re-identified Summary

Correct answers: The generated code may inadvertently replicate open-source code, potentially violating existing software licenses.; The company may not be able to claim exclusive copyright ownership over the AI-generated code.

LLMs are trained on vast amounts of public data, including open-source repositories. A major legal risk is that the model might generate code that closely matches copyrighted open-source code, potentially violating licenses (like GPL) if used in a closed-source commercial product.

In many jurisdictions, copyright law requires human authorship. Code generated entirely or primarily by an AI model may not be eligible for copyright protection, meaning the company might struggle to legally protect their product from being copied by competitors.

Correct answer: Explicitly instruct the model to ignore demographic markers and evaluate solely based on predefined, objective skill criteria.

LLMs can inherit biases present in their training data. In sensitive applications like hiring, ethical prompt development requires explicit instructions (constraints) directing the model to ignore names, genders, or demographic markers, and to base evaluations strictly on a provided rubric of objective skills. This helps mitigate unconscious bias in the output.
