A is incorrect: Fine-tuning the model to permanently memorize HR policies may seem like a fast solution, but it would require retraining or fine-tuning the model every time policies change. This contradicts the requirement of updating content quickly without the need for retraining or fine-tuning the model.

B is correct: Retrieval-augmented generation (RAG) is the appropriate pattern here because it allows the model to ground its answers in the most relevant policy snippets retrieved from the indexed store at inference time. This ensures that the answers are always based on the latest approved policy documents without the need for constant model retraining.

C is incorrect: Pure prompt engineering, where the full policy manual is pasted into the system prompt every morning, is not suitable for this scenario. It would not allow for quick updates when policies change, as it would require manual intervention to update the prompt every time a policy changes.

D is incorrect: Data masking, where policy content is removed from the prompt so the model can generalize without constraints, would not be appropriate in this case. The requirement is to ensure that answers are grounded in the latest approved policy documents, which would not be possible if the model is not provided with the necessary policy context for generating answers.

A is incorrect: Running nightly database backups for all systems is not directly related to the core benefit of generative AI for knowledge workers. While data backup is important for data security and integrity, it does not specifically address the immediate value of generative AI in enhancing productivity and efficiency for knowledge workers.

By automating the process of creating and summarizing business content, generative AI can save time, improve productivity, and enhance the quality of output for knowledge workers, making it a valuable tool for content generation and management.

D is incorrect: Provisioning and patching virtual machines in multiple regions is an important task for IT infrastructure management, but it does not directly relate to the core benefit of generative AI for knowledge workers. Generative AI is more focused on enhancing cognitive tasks, such as content creation and analysis, rather than infrastructure provisioning and management.

A is correct: RAG (Retrieval-Augmented Generation) adds the capability to retrieve relevant documents for the model without the need to retrain the entire model every time a document changes. This allows the AI system to always reflect the latest project documents by dynamically retrieving the necessary information.

B is incorrect: Training a new model on all documents is not necessary when using RAG in this kind of solution. RAG enables the system to retrieve relevant documents for the model without the need for retraining, making it unnecessary to train a new model every time a document changes.

C is incorrect: Shortening prompts to reduce latency is not directly related to what RAG adds to the solution. RAG focuses on retrieving relevant documents for the model without retraining, rather than reducing latency by shortening prompts.

D is incorrect: Encrypting project files at rest is important for data security but is not specifically related to what RAG adds to the solution. RAG's main benefit in this context is the ability to retrieve relevant documents for the model without the need for retraining.

A is incorrect: Allowing each team to choose any public AI tool with no central oversight can lead to inconsistency, lack of standardization, and potential risks related to data use, compliance, and accountability. This approach does not reflect strong governance principles for AI use as it lacks centralized control and oversight.

B is incorrect: Focusing only on model performance and ignoring regulations neglects important aspects of AI governance such as risk assessment, data use policies, and compliance requirements. Strong governance principles for AI use require a holistic approach that considers all relevant factors, not just model performance.

C is correct: Defining policies, assigning owners, and requiring risk reviews for AI projects is a strong governance approach that ensures accountability, compliance, and risk management. By establishing clear guidelines, assigning responsibility, and conducting thorough reviews, organizations can mitigate risks and ensure ethical and compliant AI use.

Strong governance principles for AI use involve establishing internal policies, guidelines, and oversight mechanisms to ensure responsible and ethical AI deployment.

A is incorrect: Prompt injection is not the correct term for the described pattern where an AI assistant queries a search or vector index before feeding the results into the model for generating a response. Prompt injection typically refers to the process of providing additional information or context to a model during training or inference.

B is correct: Retrieval-augmented generation (RAG) accurately describes the pattern where an AI assistant first queries a search or vector index, uses the results as context, and then generates a response without retraining the model. RAG is specifically designed for scenarios where the model needs to reason with up-to-date internal content.

C is incorrect: Fine-tuning involves adjusting the parameters of a pre-trained model on a specific dataset to improve performance on a particular task. While fine-tuning can be part of the overall AI assistant development process, it is not the specific pattern described in the scenario where the assistant leverages search or vector indexes for up-to-date content.

D is incorrect: Zero-shot prompting refers to a scenario where a model generates responses without any specific training examples or prompts. While zero-shot prompting is a valid technique in AI, it does not align with the described pattern of querying indexes for internal content before generating a response.
