Option B is correct because Cortex Agents orchestrate across structured and unstructured data sources, planning tasks and using tools like Cortex Analyst for structured data and Cortex Search for unstructured data. Option C is correct as 'Reflection' is a key component where the agent evaluates results after each tool use to determine next steps. Option E is correct because Cortex Agents allow the implementation of custom tools using stored procedures and user-defined functions (UDFs). Option A is incorrect; this describes Cortex Search, which is a tool that Cortex Agents can utilize, but not the primary, overarching capability of the agent itself. Option D is incorrect as this describes Cortex Fine-tuning, a separate capability for customizing LLMs, while agents use LLMs for orchestration.
