問題文

A design must choose a checkpoint store for workflows that run across multiple instances behind a load balancer. Which store is appropriate?

選択肢

1. The model deployment's own conversation store
2. A shared external database such as Azure Cosmos DB, so any instance can read the state written by another instance
3. The local file system of each instance
4. An in-memory store, since it has the lowest latency and the load balancer can be configured to send every request in a session back to the same instance, so the state is always found where it was written
