NEW QUESTION # 46
A Generative AI Engineer is building a multi-turn chat app with LangGraph on Databricks. The app must persist chat history-messages, roles, timestamps, and session IDs-for many concurrent users, support SQL queries, and stay governed in Unity Catalog. The engineer also wants ACID guarantees, low-latency reads and writes, and an easy way to sync chat data into Delta tables for analytics and model training.
Which approach fits these requirements?
Answer: A
Explanation:
Lakebase provides a Postgres database suited to transactional application state, including concurrent chat- history reads and writes. A Postgres-backed LangGraph checkpoint or memory component can persist conversation state across requests and application restarts. SQL support and transactional guarantees address the application's operational requirements. Databricks also documents registering Lakebase databases in Unity Catalog and feeding Lakebase changes into Delta tables for downstream analytics. These integrations require appropriate configuration and permissions; they are not automatic simply because a table exists.
MLflow runs are intended for experiment and application tracking rather than serving as a low-latency conversation database. Per-turn Spark writes introduce unnecessary processing overhead, while driver- memory storage with periodic snapshots risks losing recent conversation state. Databricks documentation
NEW QUESTION # 47
A Generative AI Engineer is deploying an agent using Mosaic AI Model Serving. The agent needs to access various Databricks resources, including Vector Search, Databricks SQL, and Functions. They need to find the easiest and best-practice way to authenticate the deployed agent to access these resources.
What approach should they choose?
Answer: C
Explanation:
For agents deployed through Model Serving, Databricks supports automatic authentication passthrough for declared resources. The engineer records the agent's dependencies through the resources parameter when logging the model. During deployment, Databricks checks the deployer's access, creates a service principal for the agent model version, grants the required resource access, and supplies short-lived credentials.
Credential rotation is handled automatically. Supported dependencies include Vector Search indexes, SQL warehouses, and Unity Catalog functions. This approach avoids embedding secrets in source code or recording authentication tokens as model artifacts. Permissions on the serving endpoint govern access to that endpoint; they do not independently establish all downstream resource permissions. All required dependencies, including relevant underlying resources, must be declared correctly. Databricks documentation
NEW QUESTION # 48
A Generative Al Engineer is helping a cinema extend its website's chat bot to be able to respond to questions about specific showtimes for movies currently playing at their local theater. They already have the location of the user provided by location services to their agent, and a Delta table which is continually updated with the latest showtime information by location. They want to implement this new capability In their RAG application.
Which option will do this with the least effort and in the most performant way?
Answer: A
Explanation:
The task is to extend a cinema chatbot to provide movie showtime information using a RAG application, leveraging user location and a continuously updated Delta table, with minimal effort and high performance. Let's evaluate the options.
Option A: Create a Feature Serving Endpoint from a FeatureSpec that references an online store synced from the Delta table. Query the Feature Serving Endpoint as part of the agent logic / tool implementation Databricks Feature Serving provides low-latency access to real-time data from Delta tables via an online store. Syncing the Delta table to a Feature Serving Endpoint allows the chatbot to query showtimes efficiently, integrating seamlessly into the RAG agent's tool logic. This leverages Databricks' native infrastructure, minimizing effort and ensuring performance.
Databricks Reference: "Feature Serving Endpoints provide real-time access to Delta table data with low latency, ideal for production systems" ("Databricks Feature Engineering Guide," 2023).
Option B: Query the Delta table directly via a SQL query constructed from the user's input using a text-to-SQL LLM in the agent logic / tool Using a text-to-SQL LLM to generate queries adds complexity (e.g., ensuring accurate SQL generation) and latency (LLM inference + SQL execution). While feasible, it's less performant and requires more effort than a pre-built serving solution.
Databricks Reference: "Direct SQL queries are flexible but may introduce overhead in real-time applications" ("Building LLM Applications with Databricks").
Option C: Write the Delta table contents to a text column, then embed those texts using an embedding model and store these in the vector index. Look up the information based on the embedding as part of the agent logic / tool implementation Converting structured Delta table data (e.g., showtimes) into text, embedding it, and using vector search is inefficient for structured lookups. It's effort-intensive (preprocessing, embedding) and less precise than direct queries, undermining performance.
Databricks Reference: "Vector search excels for unstructured data, not structured tabular lookups" ("Databricks Vector Search Documentation").
Option D: Set up a task in Databricks Workflows to write the information in the Delta table periodically to an external database such as MySQL and query the information from there as part of the agent logic / tool implementation Exporting to an external database (e.g., MySQL) adds setup effort (workflow, external DB management) and latency (periodic updates vs. real-time). It's less performant and more complex than using Databricks' native tools.
Databricks Reference: "Avoid external systems when Delta tables provide real-time data natively" ("Databricks Workflows Guide").
Conclusion: Option A minimizes effort by using Databricks Feature Serving for real-time, low-latency access to the Delta table, ensuring high performance in a production-ready RAG chatbot.
NEW QUESTION # 49
A Generative AI Engineer is designing a RAG application for answering user questions on technical regulations as they learn a new sport.
What are the steps needed to build this RAG application and deploy it?
Answer: D
Explanation:
The Generative AI Engineer needs to follow a methodical pipeline to build and deploy a Retrieval- Augmented Generation (RAG) application. The steps outlined in option B accurately reflect this process:
* Ingest documents from a source : This is the first step, where the engineer collects documents (e.g., technical regulations) that will be used for retrieval when the application answers user questions.
* Index the documents and save to Vector Search : Once the documents are ingested, they need to be embedded using a technique like embeddings (e.g., with a pre-trained model like BERT) and stored in a vector database (such as Pinecone or FAISS). This enables fast retrieval based on user queries.
* User submits queries against an LLM : Users interact with the application by submitting their queries. These queries will be passed to the LLM.
* LLM retrieves relevant documents : The LLM works with the vector store to retrieve the most relevant documents based on their vector representations.
* LLM generates a response : Using the retrieved documents, the LLM generates a response that is tailored to the user ' s question.
* Evaluate model : After generating responses, the system must be evaluated to ensure the retrieved documents are relevant and the generated response is accurate. Metrics such as accuracy, relevance, and user satisfaction can be used for evaluation.
* Deploy it using Model Serving : Once the RAG pipeline is ready and evaluated, it is deployed using a model-serving platform such as Databricks Model Serving. This enables real-time inference and response generation for users.
By following these steps, the Generative AI Engineer ensures that the RAG application is both efficient and effective for the task of answering technical regulation questions.
NEW QUESTION # 50
Generative AI Engineer at an electronics company just deployed a RAG application for customers to ask questions about products that the company carries. However, they received feedback that the RAG response often returns information about an irrelevant product.
What can the engineer do to improve the relevance of the RAG's response?
Answer: A
Explanation:
In a Retrieval-Augmented Generation (RAG) system, the key to providing relevant responses lies in the quality of the retrieved context. Here's why option A is the most appropriate solution:
Context Relevance:
The RAG model generates answers based on retrieved documents or context. If the retrieved information is about an irrelevant product, it suggests that the retrieval step is failing to select the right context. The Generative AI Engineer must first assess the quality of what is being retrieved and ensure it is pertinent to the query.
Vector Search and Embedding Similarity:
RAG typically uses vector search for retrieval, where embeddings of the query are matched against embeddings of product descriptions. Assessing the semantic similarity search process ensures that the closest matches are actually relevant to the query.
Fine-tuning the Retrieval Process:
By improving the retrieval quality, such as tuning the embeddings or adjusting the retrieval strategy, the system can return more accurate and relevant product information.
Why Other Options Are Less Suitable:
B (Caching FAQs): Caching can speed up responses for frequently asked questions but won't improve the relevance of the retrieved content for less frequent or new queries.
C (Use a Different LLM): Changing the LLM only affects the generation step, not the retrieval process, which is the core issue here.
D (Different Semantic Search Algorithm): This could help, but the first step is to evaluate the current retrieval context before replacing the search algorithm.
Therefore, improving and assessing the quality of the retrieved context (option A) is the first step to fixing the issue of irrelevant product information.
