Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

Agent threads and message history APIs
Why this is correct
Threads store conversation state and message history on the service side, allowing agents to maintain context across sessions.

Why it's wrong here
While Redis can store session state, the native Azure AI Agent Service provides built-in thread management specifically designed for agent memory.

Why it's wrong here
Cosmos DB vector collections are used for semantic retrieval in RAG, not native agent thread persistence.
