Databricks Certified Generative AI Engineer - Associate

Explanation

Option A is the correct answer because it follows Databricks' best practices for LLM deployment:

• Fine-tuning on Databricks: Databricks provides optimized environments for fine-tuning LLMs
• MLflow model registration: Enables version control, model tracking, and reproducibility
• Databricks REST API endpoint: Provides scalable, managed serving infrastructure with automatic scaling, monitoring, and security

Why other options are incorrect:

• Option B: Pre-trained models ARE suitable for Foundation Model APIs - the key is proper fine-tuning and deployment, not complete retraining
• Option C: LLMs cannot be stored as Delta tables; they are large model artifacts that require specialized serving infrastructure
• Option D: Downloading locally defeats the purpose of Databricks' managed infrastructure and doesn't provide the scalability benefits of Databricks serving endpoints

Key benefits of Option A approach:

• Automatic scaling based on traffic
• Built-in monitoring and logging
• Security and access controls
• Cost optimization through managed infrastructure
• Seamless integration with Databricks ecosystem
