       answer: To achieve zero message loss in AIO GA1, a minimum 3-node cluster is required. This configuration allows for one node to reboot or go offline without data loss. However, if the entire cluster goes down or enough nodes are lost to disrupt quorum, message loss may occur.

          Is MQTT with QoS 2 supported in Azure IoT Operations?
-      answer: Currently, MQTT with QOS 2 is not supported. QoS 2 provides "exactly once" message delivery, but it requires additional processing and storage overhead, which can impact performance and scalability, particularly in high-throughput IoT environments. Azure IoT Operations prioritizes QoS levels 0 and 1 for efficient message handling, balancing reliability and resource management.

           Is message persistence supported in Azure IoT Operations?
       answer: At AIO GA1, full message persistence is not going to be supported - the capability will be added post-GA. Currently, messages are held in memory with optional spill over to disk. However, if there is pod restart for any reason, messages that were written to disk cannot be restored.
