Question 1

Which vector database is most commonly used to store and retrieve embeddings in Retrieval-Augmented Generation (RAG) pipelines?

Accepted Answer

Pinecone

Answer

Pinecone is a purpose-built vector database widely used in RAG pipelines to store and perform similarity searches on embeddings.

Question 2

What is the primary role of LangChain in AI application development?

Accepted Answer

Orchestrating LLM calls, memory, and tool integrations into chains

Answer

LangChain is a framework that orchestrates LLM calls, memory management, and external tool integrations into composable chains.

Question 3

A client wants to deploy an open-source LLM on their own servers to avoid data leaving their network. Which tool best supports this use case?

Accepted Answer

Ollama

Answer

Ollama allows users to run open-source LLMs locally or on private servers, keeping data fully on-premises.

Question 4

Which technique in prompt engineering explicitly instructs a model to reason step-by-step before producing its final answer?

Accepted Answer

Chain-of-thought prompting

Answer

Chain-of-thought prompting encourages the model to show intermediate reasoning steps, improving accuracy on complex tasks.

Question 5

What does the 'temperature' parameter control in LLM inference?

Accepted Answer

The randomness or creativity of model outputs

Answer

Temperature scales the probability distribution over next tokens; higher values produce more random, creative outputs while lower values produce more deterministic ones.
